Tungsten Carbide Cobalt Powder – LA-3203S-25 (-325 +15u) WC-Co 83/17, agglomerated and sintered

linage logo
SKU: LA-3203S-25 Categories: ,

These Tungsten Carbide coatings have higher toughness, ductility and fretting resistance than the 12% Cobalt variety. Appropriate for non-corrosive applications under 1000F.

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.
