Category：

Metal minerals

Foam iron powder, also known as sponge iron powder, is a kind of iron powder added with foaming agent in a high temperature furnace above 1500 ℃ to make the iron powder become loose and porous. It is used in friction materials and can adjust the friction performance: the friction coefficient is stable, and its specific gravity is relatively light compared with the reduced iron powder. Its porous structure is conducive to reducing the brake noise of semi-metal friction material products in use.
