Stellite Series Cobalt-Based Alloy Powder -

Stellite Series Spherical Cobalt-Based Alloy Powder

Stellite Series Cobalt-Based Alloy Powder—Stellite series alloy is a family of cobalt-based alloys known for their exceptional hardness, wear resistance and corrosion resistance.

Stellite alloys typically contain significant amounts of chromium, tungsten and carbon, along with other elements like molybdenum or nickel, depending on the specific grade. Below Table showed chemical composition of our common Stellite series powders.

Truer spherical Stellite alloy powders can commonly used in additive manufacturing (3D printing), thermal spray coatings, and hardfacing processes depending on its particle size distribution.

We can provide different particle size according to customer’s application, such as 0-45um, 0-53um,15-45um, 15-53um, 45-105um, 53-150um or customized.It can be produced by gas atomizing process and PREP process.
