Tungsten Carbide Powders - 88WC 12Co

Tungsten Carbide Cobalt Chrome Powder – LA-3291S-25 (-325 +15u) WC-CO-CR 86/10/4, Agglomerated and Sintered

linage logo
SKU: LA-3291S-25 Categories: ,

Appropriate for applications under 1000°F. The CoCr matrix has higher abrasion and corrosion resistance than just Co alone. Can be used as a Hard chrome replacement.

Wear resistant thermal spray coatings of tungsten carbide are used for their hardness and wear resistance. When choosing a tungsten carbide powder, the particle size and type of carbide selected are important in determining the correct material to combat various forms of erosion, abrasion and wear. Whereas the amount of metal matrix in the coating (nickel, cobalt, or alloy) will depend on the toughness and abrasion resistance required.
