Applications of Cobalt Alloys

We all know the beautiful blue that radiates from raw cobalt, but have you ever heard of cobalt alloys? This alloy is a cobalt-chromium “superalloy” specifically designed for high wear resistance and superior performance in hostile environments. Therefore, cobalt alloys are resistant to cavitation, erosion, corrosion, galling, and abrasion. Read on to learn more about this metal alloy.

Cobalt Alloy and Its Applications

What are the uses for cobalt alloys?

What are Cobalt Alloys?

Cobalt alloys are used to cope with extreme wear and tear. By introducing a variety of other components, it can be specifically molded for a particular use. The different varieties of this alloy can take in an array of different elements such as

  • Nickel
  • Iron
  • Carbon
  • Magnesium
  • Sulfur
  • Silicon
  • Titanium

Then, the material is commonly used in environments with temperatures ranging from 600° to 1112°F.

Applications of Cobalt Alloys

Cobalt can be found in numerous products, such as lathes, medical tools, cast structure of dental prosthesis, and other bone replacements. Cobalt is likewise used in machine gun barrels, M2HB machine guns, poppet valves, valve seats, and the exhaust valves of an internal combustion engine.

Finally, to add to its numerous uses, there are also manufacturers that use this metal alloy in saw teeth, hard facing, and acid-resistant machine parts.

In the medical field, cobalt is oftentimes used since the radioactive isotope found in cobalt can treat malignant tumors and skin diseases. Hence, aside from cobalt alloys, cobalt in general is really helpful in the field of medicine. Additionally, cobalt is also used in adhesives and catalysts.

Outside of the medical field, it can be used as an adhesive in the production of rubber tires and catalysts in petrochemical production.

Cobalt is also used in rechargeable battery materials such as nickel-metal hydride batteries and lithium-ion batteries. However, it is widely used for lithium-ion batteries because of its positive electrode component. The presence of cobalt in lithium batteries to be more environmentally protective, has high dense energy, and wide voltage range.

Seamless Rings: Are Seamless Rings Right for You?

The process of forging seamless rings plays a significant role in the manufacturing of other important components. Forging is a technique of manufacturing strong, typically metal, components for use in machinery. The foraged items can be made for when apparatuses are required for the expansion of wind turbines or high-quality gears for mechanics. Seamless ring forging is used to manufacture durable, high-quality products.

The What And How of Seamless Rings

Materials Used

A distinguishable aspect of seamless rings is dependent on the material used. With every tool and metal component in the manufacturing industry, it’s vital they are created to be almost indestructible. This includes literal hardness, strength, and the ability to resist wear and tear as they age.

Among the three elements, the most important is the ability to withstand wear and tear. Because most of these products will be used in engines and machines, they will get beat up pretty well. These tools and components must also sustain heat as these are exposed to high temperatures.

Types of Steel

How are seamless metal rings made?

The types of steel used for seamless rings are:

  • Stainless steel
  • Alloy steel
  • Carbon steel

Stainless steels contain a higher amount of chromium than other types of steel. As a result, seamless rolled ring forgings made of this type of steel are corrosion resistant and therefore, should not rust.

Alloy steels have great strength, hardness, wear resistance, and enhanced toughness. However, additional heat treatment may be required in order to achieve these attractive properties.

Lastly, carbon steels possess properties that are similar to iron. Within carbon steels, there are additional classifications: low carbon steel, medium carbon steel, and high carbon steel. The lower the carbon content, the cheaper and easier it is to shape. 


How are seamless rings made?

The seamless ring process begins by taking a circle-shaped metal that has already been pierced to look like a doughnut, thus the ring name. The shape is then heated beyond the required temperature for recrystallization. Finally, it is shaped into the desired shape.

Castings | What are Centrifugal Castings?

A casting is a type of manufacturing process that many different industries use. The process involves pouring a liquid material into a mold that exhibits the desired shape and size of the final part. Once the liquid material turns to solid form, it is broken out of the mold to complete the casting process. Companies usually use castings to create shapes that are too complex for other methods.

There are many different types of castings. These include investment casting, sand casting, die casting, and centrifugal casting. Today we are going to discuss centrifugal casting.

What are Centrifugal Castings?

Centrifugal casting is a method of casting to produce parts that are cylindrical in shape. It is one of the best techniques for making thin-walled cylinders. Parts of this method are cast with iron, steel, stainless steel, glass, and alloys of aluminum, copper, and nickel. Some of the most common parts produced from this method of casting are pipes, flywheels and cylinder liners. The biggest benefit of using centrifugal castings is that it is one of the only methods that allows you to easily and efficiently cast a shape with rotational symmetry. Although these shapes can be cast by other means, it is much more difficult to do so without centrifugal casting.
