Iron Pyrite

Iron Pyrite, distributed by Washington Mills, is specially prepared from carefully selected pure mono-crystalline iron pyrites (FeS2). The material consists of finely grained Pyrite crystal splinters, which increase the thermal conductivity, the tensile strength, and the porosity of resin-bonded grinding wheels and cut off wheels.
