Ni60A Thermal Spray Alloy Powder (base layer) Cr50, Cocraly, Ni20cr, Ni/Al, Nicrcoaly, Nicral

The Ni Ni60A is Ni-Cr-B-Si alloy powder with high hardness. Self fluxing, wettability and spray welding of excellent and relatively low melting point, the spray welding layer has high hardness, corrosion resistance, wear resistance, heat resistance characteristics, difficult to cutting, with wet grinding is appropriate. Suitable for oxygen acetylene flame or plasma spray welding technology, commonly used in corrosion resistance, wear resistance, and especially the sliding wear resistance of parts of the protective and repair, such as the drawing roller, a cam, a plunger, a rolling mill roller conveyor, valve and so on.
