Atomized nickel powder is widely used in nickel cadmium, nickel hydrogen batteries, filters, binders for high density and high melting point materials, powder metallurgy additives, precision alloys, special steel, stainless steel welding rods, petrochemical catalysts and new compounds, getters for electron picture tubes, high frequency or ultra high frequency magnetic materials, etc.
Nickel powder is mostly used as matrix bonding material of diamond thin-wall bits and cutting chips used in construction industry, mining diamond bits and cemented carbide bits used in oil and gas industry; Most of the tools used in metal material processing, automobile and motorcycle mechanical grinding are diamond abrasives, and the matrix material is mostly nickel powder. It includes ultrafine nickel powder, electrolytic nickel powder and reduced nickel powder.
Nickel powder is for diamond tools (metal matrix alloy powder): metal bond is one of the key factors to determine the quality of diamond saw blade, cutter head, grinding wheel, thin-wall drill and other products. After the diamond is determined, the quality of metal bond becomes the decisive factor. Cobalt powder and nickel powder can be used as the main binder, but the price of cobalt powder is higher.
In diamond tools, matrix refers to the metal sintered body that encapsulates diamond. The function of matrix is to hold the diamond and make it cut without falling off too early. The matrix is generally composed of a variety of metal elements, mainly using low melting point metal powder as binder, such as nickel powder.
