Four stroke engines are internal combustion engines whose pistons complete four separate “strokes” in order to convert fuel into motion. Each stroke is completed as the piston takes a full stroke along the cylinder. The four strokes in a four stroke engine cycle are as follows: Intake, compression, combustion, and exhaust. Continue reading to learn more about each stroke and how the four stroke combustion cycle works.

Otto Cycle

Nikolaus Otto was the man who invented the four stroke cycle back in the late 1800’s. For this reason, the four stroke combustion cycle is also commonly referred to as the Otto cycle. In contrast, there is a man named James Atkinson that invented a single-stroke combustion cycle, appropriately called the Atkinson cycle. This cycle is applied in modern hybrid electric technologies. As for the four stroke engine cycle, here is a breakdown of each stroke:

Intake
During the intake stroke, the intake valves open, allowing the pistons to travel down along the cylinder, increasing the cylinder’s volume, and allowing the engine to “take in” a full cylinder of air and fuel. Only a tiny drop of gasoline is mixed with air to perform this stroke.

Compression
The air and fuel mixture within the engine’s cylinders is compressed when the intake and exhaust valves close and the pistons move back to the top of the cylinders. As the pistons move up, they compress the air and fuel mixture into the cylinder heads.

Combustion
At the combustion stroke, ignition takes place. This stroke begins at the second revolution of the cycle. Once the compressed air enters the cylinder heads, the engine’s spark plug ignites this air and creates power. This combustion forces the pistons to travel back down the cylinders.

Exhaust
At the exhaust stroke, the pistons travel back up the cylinders and the exhaust valves open. This ejects the residual air fuel mixture emissions through the exhaust valves and out through the tailpipe.

Old Car Engines

When your car engine takes a turn for the worst, you may feel overwhelmed at the thought of replacing it with a new one. After all, the cost of engine replacement these days is incredibly high. In fact, you could buy a perfectly good used car for the price of some brand new car engines! Fortunately, you have the more cost-effective option of purchasing a used car engine. To make the most out of broken down car engine, sell it to an Indianapolis used auto part buyer for cash on the spot. Then apply this profit toward a new car engine!

Top 3 Applications of Aluminum Anodizing

In its natural state, aluminum has a thin protective layer of oxide that makes it resistant to damage and corrosion. The more pure the metal, the higher the resistance. But in the metals market, many aluminum commodities are manufactured with other alloying agents, such as nickel, iron, copper, and steel. This makes them more vulnerable to abrasion and corrosion. For this reason, many metal manufacturers are using a process known as anodizing to strengthen aluminum’s resistance to damage. Continue reading to learn more about the anodizing process and the top three most common applications in the metals industry.

The Process of Anodizing

Anodizing is an electrochemical process that promotes the formation of an additional, thicker layer of aluminum oxide to aluminum alloys. This provides more strength and resistance to corrosion and damage faster than it could naturally. The anodization does not strengthen the aluminum base material; it only adds an additional layer of protection that retains a higher resistance to wear and tear. It can be effective for other metals, but it has the biggest impact on aluminum. The process starts by dipping the metal object into a reservoir filled with an electrolytic solution and a cathode made of aluminum or lead. Next, an electrical current is passed through the aluminum, which is acting as the anode. This current promotes and expedites the oxidation of the aluminum.

The three most common applications for anodizing:

Corrosion Resistance

Commodities that benefit the most from anodizing are those that are at risk of corrosion. This includes commodities that are regularly submerged or in contact with water, including boats, dock structures, auto parts, plumbing, and more.

Abrasion Resistance

Non-anodized aluminum alloys are softer and more malleable than oxidized aluminum alloys. Anodizing provides additional protection against abrasion, fracture, and other forms of damage. In fact, it is so highly resistant to abrasion that aluminum oxide is often used to manufacture sandpaper.

Dyeing

Dyeing is the process of integrating color into aluminum alloy commodities, such as bikes, parts, tools, and more. Since the layer of oxide that forms from anodizing is porous, the dyeing process is easier than without the protective layer.

Tips for Cleaning Stainless Steel

Stainless steel trends are on the rise, and they’re not just for appliances anymore. Several office and household commodities are being introduced to the market in stainless steel versions. Items like countertops, backsplashes, phone cases, laptops, furniture, jewelry, electronics, and more can be bought in stainless steel. Steel finish, however appealing, is not actually stainless. In fact, one of the downsides to this type of finish is that it retains every single fingerprint that seems to come in contact with it. For this reason, it is helpful to learn some easy methods and techniques for cleaning stainless finishes, and keep your stuff shiny and finger-print free!

Stainless Steel Cleaning

Stainless steel requires more than a simple wash rag and wipe-down. It requires certain specialized products and cleaning techniques for optimal shine and protection. You won’t get far using dish detergent and water. It is best to purchase a store-bought stainless steel cleaner and polisher. These generally come in kits with the proper brush and polishing tools as well.

Now this may sound tedious, but it’s actually quite simple and only needs to be done once or twice a week. Simply apply the cream solution or polish to the surface, and then scrub in with the included abrasive. Use circular motions and adequate pressure. You are not just wiping imperfections away, you are conditioning and polishing the finish.
Once the polish is wiped in, you will notice a white powdery residue left over. Simply use a dry paper towel to clear this away. Last, use a dry microfiber cloth to wipe the surface down in circular motions, to remove any lasting streaks or marks. And you are done!

Restoring Stainless Finishes

When polishing doesn’t do the trick, or when steel items are past their prime, a professional cleaning company can restore the look of steel finishes with acid chemical treatments. These are called pickling and passivation acid treatments. They are meant to remove any free iron deposits and low chromium layers from the surface, to reveal shiny better-looking metal. This is a very popular service for commercial properties with stainless steel cleaning and restoration needs.

Interesting Facts About the Value of Platinum

Platinum is a precious metal that is sometimes referred to as the “Rich Man’s Gold” or “White Gold” because it is just as beautiful, but rarer than gold itself. Continue reading to learn why platinum is so valuable.

Precious Metal Recycling 1-888-586-5322

Precious Metal Recycling 1-888-586-5322

Attributes of Platinum

Platinum is a dense, malleable, and ductile metal with a silvery-white color and sheen. It is a chemical element that is assigned the symbol “Pt” with an atomic number of 78. It is considered a precious metal, making it more valuable in terms of profit. The word “platinum” is derived from the Spanish word, “Platina”, which means “little silver.” It is a heavy metal, heavier and denser than gold. One cubic foot weighs a little more than 1,330 pounds, and is about 11% denser than gold. That means that a 6 inch cube of platinum would weight about as much as you do!

Uses for Platinum

Platinum is a highly sought-after metal because it offers so many applications and uses. It is a nonreactive metal, and highly resistant to corrosion. That is why it is also considered to be a “noble metal”, which are metals that are resistant to corrosion and oxidation. Platinum won’t rust! This is why it is commonly used in the jewelry industry. For these same qualities, platinum is also commonly used to manufacture automotive parts (catalytic converters), laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and much more.

Scarcity of Platinum

Platinum is very scarce. In fact, it is one of the rarest elements found in the Earth’s crust. This is one of the primary reasons why it is so valuable. It is simply an economic matter of supply and demand. You see, there are approximately 130 tons of platinum being produced in the world each year. Larger amounts of steel are poured in a single day in the United States than the total production of platinum in one year! Eighty percent of the world’s platinum production comes from mines in South Africa. Aside from the Earth’s crust, there are also naturally occurring deposits in various alluvial rivers around the world.

Sell Your Platinum Today!

If you have old platinum jewelry or catalytic converters, you can sell these items to a scrap metal buyer and get paid cash on the spot. Platinum is currently doing well on the scrap metal market, so take advantage of the current economy and sell your platinum commodities while their value is on the up and up.

Do You Know What Makes Brass and Bronze Different From Each Other?

Brass and bronze metal may look similar, but there are distinctive differences between them. Learn what these differences are before recycling your metal!

For those looking to recycle a large amount of brass, you may want to take a closer look to ensure your brass pile is in fact, all brass. The price per pound for bronze is higher than brass, and often times, people make the mistake by assuming all “yellow metals” are brass. However, brass can have bronze in it as well, making it slightly more valuable. Continue reading to learn what the difference is between the two metals, and how to tell them apart from one another.

Brass

Brass is a non-ferrous alloy metal. “Non-ferrous” means that it does not contain any iron and lacks magnetic abilities. An “alloy” is a metal that is comprised of other metals. In the case of brass, copper and zinc are the majority metals, with most brass containing anywhere from 60 to 80% copper and 20 to 40% zinc. Zinc and copper combined makes for a stronger and more durable metal that has a yellow-ish tint.

Brass is commonly used in plumbing applications, including brass pipes and plumbing fixtures, turnings, shells, and more. However, it also have several other industry applications. For instance, brass is a common metal for making musical instruments like trumpets and trombones.

Bronze

Bronze is less common than brass. It is also a non-ferrous alloy made up of zinc and copper, so it is difficult to tell brass apart from bronze. The difference between the two alloys is simply the amount of copper content. Bronze has more copper content than brass, usually between 80 and 90 percent, which is why it is redder in color. Brass has less copper, so it is more yellow or gold in color. Bronze is also heavier and more dense than brass, so it is a common material for statutes and decorative objects. In order to tell brass from bronze, you need experience in the metal buying industry.

To determine the exact amounts of copper and zinc in a metal item, you would need some technology. There is a device called an XFR analyzer that can read metal. These are very expensive, and generally used by large scrap metal companies.

4 Benefits of Recycling Scrap Metal

Scrap Metal Recycling 1-888-586-5322

Scrap Metal Recycling 1-888-586-5322

Millions of tons of scrap metal are used and discarded each year. From bottles and cans, to vehicles, electronics, and more, metal is a highly useful commodity that is 100% recyclable. According to the Institute of Scrap Recycling Industries (http://www.isri.org), 150 million tons of scrap metal was recycled in 2008. This rate of metal recycling has remained strong over the years, and we are still recycling millions of tons of scrap metal today!

Continue reading to learn why metal recycling is so valuable to our environment, economy, and more!

❶ Environmental Protection

Recycling scrap metal is good for the environment for many reasons. For example, the mining of new metal ore creates larger amounts of harmful greenhouse gas emissions in comparison to making new products with recycled metal. These emissions cause air pollution to rise in metropolitan areas, and can even influence climate changes overtime. According to the National Institutes of Health, making new products using recycled metal produces 97% less mining waste and uses 40% less water!

❷ Energy Conservation

Scrap metal recycling conserves energy since there is no need to drill, refine, process, and manufacture new ore. Here’s a fun fact: According to the U.S. Environmental Protection Agency (EPA), recycling just one single aluminum soda can saves enough energy to power a 60-watt light bulb for more than four hours!

❸ Natural Resource Preservation

One of our most precious natural resources on Earth is our natural ore deposits. Unfortunately, there is only a limited amount. By recycling scrap metal, we can reduce the need to mine for new, virgin ore, thus preserving our planet’s natural resources.

❹ Economic Support

The scrap metal recycling industry is not only philanthropic in terms of the environment, it also aids the local economy by providing jobs, promoting cash flow, and allowing for economic gain. According to the National Recycling Coalition, the recycling industry generates virtually $236 billion each year, and employs more than one million workers across America.

The Discerning Attributes of Ferrous and Non-Ferrous Metal

Scrap Metal Recycling 1-888-586-5322

Scrap Metal Recycling 1-888-586-5322

There are various types of metal found all around the world, but all metals can be placed into one of two categories: ferrous or non-ferrous. The most distinguishing difference between ferrous and non-ferrous metal is iron. Iron is among the most common chemical elements on the planet, and found primarily in the Earth’s crust. When metal contains iron, regardless of how little the content, it is considered a ferrous metal. In contrast, non-ferrous metals do not contain any iron content. An easy way to remember this rule is to remember that non-ferrous means non-iron.

So how do you tell the difference between a ferrous and non-ferrous metal?

The answer is a magnet! If the magnet sticks to the metal, the metal contains iron, which would make it ferrous. You see, iron is a magnetic metal, so if a magnetic sticks, it must contain a sufficient amount of iron content. In some cases, the concentration of iron is too weak to attract a magnet, so additional equipment would be necessary in determining its true composition. Look below to learn some examples of ferrous and non-ferrous metals and their common applications.

Ferrous Metals

Wrought Iron: Composition is virtually 100% iron content. Common applications include fencing and ornamental gates.

Cast Iron: This strong but brittle metal contains mostly iron, but also contains anywhere from 2 to 6% carbon. It is commonly used to make engine blocks and sewer covers.

Mild Steel: Mild steel has a mostly iron composition, but also contains between 0.1 to 0.3% of carbon. Its primary application is engineering, but also non-specialized metal products manufacturing.

Carbon Steel: Iron metal containing 0.6 to 1.4% carbon content. It is commonly used to make metal cutting tools and tool parts, like drill bits and bushings.

Stainless Steel: A popular finish for home appliances, stainless steel contains iron, nickel, and chromium. Because it is stain and corrosion-resistant, it is commonly used to make surgical instruments and cutlery.

Non-Ferrous Metals

Copper: A naturally-occurring element, copper contains no iron content. Because of its electricity and heat-transfer attributes, it is commonly used to make electrical wiring, tubing, and plumbing pipes.

Aluminum: Aluminum contains manganese, copper, and aluminum content. It is highly malleable and lightweight, so it is commonly used in the aircraft manufacturing industry, but also for kitchenware, window frames, and more.

Lead: Also a naturally-occurring element, lead is a soft, but heavy, metal. It is primarily used to make batteries, roofing materials, and pipework.

Brass: Brass is made up of mostly copper, but contains up t0 35% zinc as well. It is commonly used to make ornamental commodities and electrical fittings.
