Different kinds of thermal spray powder

Ni-based self-melting alloy powder, which is based on Ni and composing of Chromium, boron, silicon, carbon, copper, molybdenum and other elements. The melting point of alloy powder is low, good self-molten performance, and it’s with good properties of corrosion resistance, abrasion resistance, heat resistance, oxidation resistance and others, it’s the most widely used welding alloy powder.

WC Based Tungsten Carbide Thermal Spray Powders: High hardness, great wear-resistant, erodent-resistant and concussion-resistant, Well-proportioned grain, great apparent density and high density. Good capability of spray-welding. And there four kinds of it, depending on its elements: WC -6Co, WC -10Co-4Cr, WC -12Co, WC -17Co spray powder.

There are two kinds of Fe-based alloy powder, one kind is stainless steel, containing more nickel and chromium; the other kind is high-chromium iron, containing more chromium and carbon.

Cobalt-based self-melting alloy powder, which is based on Co and composing of Chromium, tungsten, nickel, boron, silicon and other elements. It has the characteristics of Good High Temperature Performance, good red hardness, excellent wear-resistance and oxidation resistance.

Cu-based self-melting alloy powder, which is based on Cu and composing of Nickel, chromium, boron, silicon, manganese and other elements. It’s featured by high mechanical performance, easy machining, excellent corrosion resistance and Low friction factor.
