It is the scrap of iron. The main uses of iron powder include:
① As the raw material of powder metallurgy products, the consumption accounts for 60~80% of the total consumption of iron powder
② As the raw material of the electrode, adding 10~70% iron powder in the coating can improve the welding process of the electrode and significantly increase the deposition efficiency
③ As a spray agent for flame cutting, when cutting steel products, iron powder is sprayed into the oxygen acetylene flame, which can improve the cutting performance, expand the range of cutting steel grades, and increase the cutting thickness
④ It can also be used as reducing agent in organic chemical synthesis, carrier of copier ink, etc.
