Iron powder

Iron powder has several uses; for example production of magnetic alloys and certain types of steels.^[1]

Iron powder is formed as a whole from several other iron particles. The particle sizes vary anywhere from 20-200 μm. The iron properties differ depending on the production method and history of a specific iron powder. There are three types of iron powder classifications: reduced iron powder, atomized powder,^[2] and electrolytic iron powder. Each type is used in various applications depending on their properties. There is very little difference in the visual appearances of reduced iron powder and atomized iron powder.^[3]

Applications

Automobiles

Most iron powders are used for automobile parts.

Engine parts

Steering parts, suspension, and brake parts

Seats and door parts

Transmission parts

Additive manufacturing

Iron powders are increasingly used as feedstock in metal additive manufacturing processes. In binder jetting, fine iron powder is selectively bonded with a liquid binder and subsequently sintered to produce complex near-net-shape parts with properties comparable to conventional powder metallurgy components.^[5] Gas-atomized spherical iron alloy powders, including stainless steel grades such as 316L and 17-4 PH, are also widely employed in laser powder bed fusion for tooling, structural, and medical applications.^[6]

Other

Iron powder is also used for the following:

Bearings and filter parts
Machine parts
Hand Warmers
High strength/wear-resistant parts
Magnetic materials
Friction parts (mainly automobile parts)^[4]
As a metal energy carrier^[7]^[8]
- Wet cycle: storage of energy and generation of hydrogen using iron powders^[9]^[10]
- Dry cycle: storage of energy, production of heat and electricity using iron powders^[11]^[12]
Oxygen scavengers – can be in small pouches separate from food or directly added to food, in which case it also serves as food fortification^[13]
