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.

Understanding Forged Steel

Many people have never heard of foraged steel, but little do they know it’s used all around them. Most things made out of metal can be made stronger with forged steel! Forging was originally implemented to produce different kinds of steel ends with distinct properties. Currently, hydraulic hammers, and other forging machines and processes, make it possible for the development of steel forgings.

What are Steel Forgings?

Process and Categories of Steel Forgings

Process of Producing Forged Steel

The forging process begins by heating the steel to a high temperature, making the material more malleable and ductile. Next, it will be formed to the desired shape by applying the right amount of pressure to the steel. With the precise processing methods, steel forgings make it possible for a billet of steel to permanently be shaped without compromising its quality.

Additionally, steel forgings require a forge oven, forge furnace, or any forging heating system to sufficiently deliver the precise temperature needed. Furthermore, the deformation and thermal cycle process allow for rain refinement and metallurgical recrystallization to strengthen the finished product. This process is important to improve impact toughness and quality.


Steel forgings can be divided into 3 categories: the cold, warm, or hot forging of steel. Cold steel requires room temperature forging require a room temperature forging. The process often involves a self-heating method in which temperature may reach up to 150 degrees Celsius. This category requires high forming forces and low formability.

As for warm forgings, the temperature reaches between 750 and 900 degrees Celsius. However, just like cold steel forgings, this category needs higher forming forces but only has limited formability.

Lastly, hot forgings may reach up to 1250 degrees Celsius. Since the temperature is often above the recrystallization level, this forging category only requires low forming forces and still has good formability results.

Seamless Rolled Rings | Should I Use Seamless Rolled Rings for My Project?

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. Seamless rolled rings give your forging the best strength, fatigue resistance, and freedom from inclusions. Let’s take a look at where you can find seamless rolled rings and if you should use them for your next project.


Seamless rings offer an improved strength, fatigue resistance, and freedom from inclusions. They also have a cost advantage. This forging process results in an end product that requires fewer machining operations, reduced weight and lower costs for raw materials.


Rolled Ring forgings can be commonly found in jet engines, jet turbines, helicopter gearboxes, paper mills, windmills, and other extreme environments.


The process of creating seamless ring forgings start with the punching of a hole in a thick or round piece of billet, generally made of steel. The piece is then heated, rolled, and squeezed into a ring. It can be produced in configurations ranging from flat, washer-like parts to tall, cylindrical shapes, with heights ranging from less than an inch to more than 9 feet. The simplest and most commonly used shape is a rectangular cross-section ring.

Investment Castings | Where Can I Find the Best Investment Casting?

The investment castings process can produce the most intricate shapes in pretty much any alloy. It is the only metal working process that provides the design freedom to easily cast complex intricate shapes and assemblies. Here is more information why you should use investment casting and where you can find the best investment casting.


Investment casting provides reliable process controls and repeatability that are maintained from casting to casting.

Better for the Environment

Investment castings are produced from nine wax patterns. In most cases, the wax can be reclaimed and used again. The wax pattern allows you to see your part before it’s cast, eliminating expensive and wasteful revisions. This allows for less metal to be used.

Intricate Design

When using investment casting, engineers can do a lot to customize your product. Logos, product ID’s/numbers, letters, thru holes, slots, blind holes, external and internal splines, gears, and thread profiles are just some of the intricacies that can be done.


Ferralloy works with many different casting alloys. This allows our investment castings to be used for a variety of different industries.

Lower Cost

The initial wax injection mold to produce the patterns is often lower than other casting tooling costs. As a result, you get a more cost-effective product without having to sacrifice any quality.

Investment Casting | What are the Different Methods of Machining?

Investment casting, forging, rolling, and more. There are so many ways that you can get the best out of your metal materials. Machining can do just that. Machining is a manufacturing process that cuts a component to specific dimensions that allows them to be even more precise. But, how do metalworkers machine materials?


A milling machine rotates at a very high speed. So, a metalworker will feed the workpiece into the machine and material will be cut away in small shapes. This is ideal for components that have features like holes, slots, and pockets.


Metalworkers will use a drill bit to create a circular hole. So, drilling involves a rotary cutting tool and can perform anywhere from hundreds to thousands of rotations per minute. And, the machining will cut off little chips during this process.


Boring mills can come horizontally or vertically. Then, a metalworker can place a spindle in either orientation. Workers use this method to create clean and smooth finishes.


Facing cuts the face, or surface, of a component. This requires a planar, or flat, surface. So, the piece of metal rotates around one point. This allows for a nice and smooth face surface by removing material from the end of the piece.

Forging Rings | Why Does Corrosion Occur in Metal?

When you are working on an industrial project, you need to be able to rely on your materials. And, they need to last as long as possible. But, corrosion can lessen the integrity of metal elements. So, whether you are in the market for forging rings or other metal components, here is what you should know about corrosion:

What is Corrosion?

Corrosion is a natural process that causes the deterioration of refined metals. Over time, a chemical or electrochemical reaction will cause the metal to break down. This can reduce the durability of a metal component. It will “eat” away at the surface and eventually internal structure.

What Causes Corrosion?

There is an array of chemicals that can react with metals and alloys, causing oxidation. Even oxygen can play a role in corrosion. Rust is a very common form of corrosion. For example, iron can oxidize. It will then get a burnt orange and flaky surface. This is called rust. For structural alloys, moisture in the air can lead to corrosion.

How Can I Prevent Corrosion?

The first step to preventing corrosion is by creating high-quality, corrosion-resistant materials. Metalworkers make corrosion-resistant fabrications with materials that naturally are less susceptible to chemical deterioration. A special coating can also be put on to protect from oxidation. A professional can supply a prevention recommendation.

Are You in Need of Forging Rings?

Steel Castings | What is Near Net Shape Manufacturing?

When it comes to metalworking, there are several different methods a professional can use to create durable components. Sometimes a manufacturer is able to get a product so close to its final stage that finishing is not a requirement. This is the opposite of net shape manufacturing. Learn more about near net shaping and why it may be an option for the next time you need steel castings:

What is a Near Net Shape?

A near net shape is an industrial term that refers to a particular manufacturing technique. This name means that a product that comes out of its initial production and is very close to the final shape. The final shape is also known as the net shape. Net shape manufacturing is the opposite of near net shape. Near net shape manufacturing allows there to be less traditional finishing. Finishing includes machining and grinding.

Why Would I Choose Near Net Shape Manufacturing?

Near net shape manufacturing is a great option for those looking to save money where they can. This is because near net shape manufacturing does not require finishing steps. So, when you do not need any time of machining done, you are able to save in production costs. It also takes less time to produce near net shapes.
