Product Overview

325 Mesh Iron Powder is a fine, high-purity iron powder (99.9% Fe) with a particle size under 44 microns. Iron has a melting point of 2,795°F (1,535°C) and a density of 0.284 lbs/in³ (7.87 g/cm³). The fine particle size gives a large reactive surface area and allows the powder to blend evenly with other metal powders, binders, and chemicals.

Fine iron powder is used in powder metallurgy and sintered parts, in metal injection molding feedstocks, and as an iron source in specialty alloy and additive manufacturing work. Its high surface area makes it an effective reducing agent and reactant in chemical processing, and it is widely used in laboratories and teaching settings. Other applications include magnetic materials and particles, oxygen absorbers, and friction and brake formulations.

Supplied as -325 mesh powder in sealed containers to protect against moisture.

Solubility Note

Fine iron powder oxidizes in humid air, store sealed and dry. Disperses readily in binders and blends uniformly with other metal powders.

-325 mesh means the powder passes through a 325 mesh screen, which has openings of about 44 microns. All particles are smaller than that size. Fine powders like this blend more evenly, sinter more readily, and react faster than coarser grades because of their larger surface area per pound.

The largest uses are powder metallurgy and sintered components, where fine iron powder is pressed and sintered into parts, and chemical processing, where its surface area makes it an effective reducing agent. It is also used in metal injection molding, magnetic products, oxygen-absorbing packets, friction materials, and laboratory and educational work.

Keep the powder in a sealed container in a cool, dry place. Fine iron powder oxidizes (rusts) when exposed to moisture, which reduces purity and changes how it flows and sinters. Like all fine metal powders, avoid creating dust clouds and keep away from ignition sources. Refer to the Safety Data Sheet for full handling guidance.
