What Is Stellite?

In the world of machining, there are many different raw materials that can be used. While most of us have heard of aluminum or steel, one alloy that is quickly growing in popularity is that of Stellite. Let’s get into what Stellite is, and how it’s used.

What is it?

Stellite contains many different metal components and is a non-magnetic alloy. The primary metals used in Stellite are cobalt and chromium. While many people think that this sort of material is new, it’s actually been around since the early 1900s and was often used when machining cutlery. This alloy was invented by Elwood Haynes. While the trademark has switched hands over the years, Stellite is a commonly used alloy in machining parts Pittsburgh PA operations and factories.

The other factor that makes this alloy so popular is the resistance it has to weather and wear and tear. Different mixes of Stellite can be used for different applications that require stronger metals such as nickel, iron, and titanium.

Stellite is often used for applications that reside within temperatures from 600 to 1112 degrees Fahrenheit. The ability to maintain its strength at these temperatures makes it a very popular machining alloy to be used in high-heat applications and machinery.

How it’s Used

In the process of machining, this type of material is used on cutting tools. In fact, most saws and metal teeth on saws are machines and made with Stellite. Stellite can go beyond common tools and can be much more sophisticatedly used in hip replacements and even heart valves.  The basic rule of thumb is that if a metal will be subject to erosion, corrosion, or extreme heat, Stellite is a wonder material.

As you can see, Stellite is a popular machining alloy for several different reasons and it used in many commonplace applications.
