Detailed introduction
Also known as refined iron ore, it is processed by water washing and flotation. It is the raw material for manufacturing iron oxide black. When used as filler for friction materials, it can replace chromite to provide friction coefficient, and its wear resistance is less than chromite. It is mainly used to reduce iron powder in the friction industry, and steel fiber plays a role in increasing friction in semi-metal friction materials, making its product coefficient stable.
