Our additive powder portfolio offers a range of metal powders with the material characteristics needed for use in industries such as aerospace, automotive, oil and gas, power generation, medical, dental, tool and die, and other general processing industries.
STELLITE™ Additive Powder
The cobalt-based Stellite™ alloys are some of the most well-known and successful alloys in the world, with outstanding “all-round” properties. They combine excellent mechanical wear resistance, especially at high temperatures, with good corrosion resistance. The Stellite™ alloys are mostly cobalt-based with additions of Cr, C, W, and/or Mo.

NISTELLE™ Additive Powder
The nickel-based Nistelle™ alloys are designed for corrosion resistance rather than wear resistance, particularly in aggressive chemical environments where their high chromium and molybdenum contents provide excellent pitting resistance. As a class, they are also generally resistant to high-temperature oxidation and hot gas corrosion.

DELCROME™ Additive Powder
The iron-based Delcrome™ alloys were developed to resist abrasive wear at lower temperatures, typically up to 200º C. These alloys also provide moderate corrosion resistance and metal to metal wear resistance.
