Application of Atomized Nickel Powder

       

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.
