English name: iron/iron dust/iron filings/iron powder

CAS: 7439-89-6

Molecular formula: Fe

Molecular weight: 55.85

Density: 7.86g/cm3

Production 1. Copper slag and iron powder; Iron 47 52% (average 49%), 325 mesh, specific gravity 4.1g, moisture 8-11, sulfur 0.3%, titanium 4.07%, zinc 1.65%, magnetic material 89.01.

2. Zinc slag and iron powder: iron 73.24%, zinc 0.41%, sulfur 2.09%, containing trace elements such as gold, silver, and copper inside.

Process: Zinc kiln slag is crushed by a precision mill and then separated by a magnetic separator to obtain iron powder.

Purpose:

Mainly used in powder metallurgy, manufacturing of mechanical parts, production of friction materials, antifriction materials, superhard materials, magnetic materials, lubricants and their products. Used in the electronic industry and powder metallurgy. Used as a reducing agent. Secondly, iron powder is widely used in chemical engineering, cutting, heating materials, welding rods, etc.
