88WC-12Co hard metal powders, WC-Co tungsten carbide cobalt thermal spray powder
Tungsten carbide cobalt hard metals are composites of tungsten carbide particles (either tungsten carbide alone or in combination with smaller amounts of other carbides) with metallic cobalt powder as a binder, pressed into a compact, solid form at high temperatures by a process known as “sintering.” Cobalt–tungsten carbide hard metals have properties of extreme hardness, abrasion resistance, and toughness and are used primarily in cutting tools and wear-resistant machine parts.
For the tungsten carbide cobalt thermal spray powder, we could supply 94WC-6Co, 90WC-10Co, 88WC-12Co and so on, 60nm.

Hard metals are used primarily in cutting tools, to machine tempered steel, in rock drilling bits, and in a variety of tools. They are produced by preparing tungsten carbide particles from tungsten metal or tungsten oxide and carbon, adding a mixture of
powdered cobalt metal and other compounds to produce powders of cobalt–tungsten carbide, which are then pressed, shaped, sintered, and finished as hard-metal products. The potential exists for general-population exposures to cobalt–tungsten carbide hard metals or to powders containing cobalt and tungsten carbide for persons living near facilities that manufacture or process cobalt-tungsten carbide hard metals or hard-metal products.
