product details
(1) Product features: reduced iron powder, gray or black powder, also known as "double absorbent", can absorb moisture and oxygen in the air, commonly used for food preservation.
The reduced iron powder is generally formed by reduction of Fe3O4 in hydrogen or carbon monoxide gas stream under high heat condition, and its main component is loose iron. The surface of reduced iron powder is active because of its powder shape and loose microstructure. It is often used as high quality reducing agent in chemical production and laboratory operation.
(2) Product application: main additives of hard alloy, saw blade, tool, drill, and other hardware tools, solder addition, high-strength structural parts in powder metallurgy, hard alloy, diamond tools, rubber and plastic products, soft magnetic powder parts, chemical catalyst and food industries.
(3) Product specification: 80 mesh, 100 mesh, 200 mesh, 300 mesh, 400 mesh, 500 mesh, 600 mesh or according to customer requirements.
