Over 80 Years of Tungsten Manufacturing & Processing Innovation
Kennametal manufactures tungsten & heavy metal powders using automated reduction of tungsten oxide. Kennametal’s process starts from tungsten ore (Wolframite/Scheelite), which is chemically processed into Ammonium Paratungstate (APT). APT is then converted into tungsten oxide and subsequently reduced to pure tungsten powder. Kennametal’s powders conform to some of the highest purity and PSD specifications from a wide variety of markets including: aerospace, oil & gas, energy, chemical processing, and transportation.
In addition to our portfolio of tungsten powders, Kennametal brings over 80 years of tungsten and tungsten carbide manufacturing & processing innovation dating back to when our founder, Philip M. McKenna, created the first tungsten-titanium carbide alloy for cutting tools and wear components. Our manufacturing and applications engineers take pride in carrying on Philip McKenna’s entrepreneurial spirit and delivering high performance material solutions to all of our customers.
Standard tungsten (W) metal powders are available in a wide variety of sizes (0.6-22um) at purity levels >99.9%. Applications for standard tungsten powders include: Electrical contacts, catalysts, mill products, munitions, and radiation shielding.
Crystalline tungsten (W) metal powders are available in a wide variety of sizes (+60 to -325 mesh) at purity levels >99.9%. Applications for standard tungsten powders include: Electrical contacts, products, oil & gas, munitions, and radiation shielding.
Granulated tungsten powders differ from standard W powder in that the material is processed by pressing, sintering, and crushing tungsten to produce coarser mesh size particles. Applications for standard tungsten powders include: Hardfacing Adders, wear rate modifiers, particle accelerators, and catalysts.
Tungsten metal powders are tungsten metal powders that are blended with a metal matrix (typically copper or nickel) to create a pseudo-alloy of tungsten. Tungsten metal powders are made to customer spec and are available in a wide variety of cuts with a variety of additives.
