IRON325AT: High Purity, High Density Free-Flow Iron Powder
IRON325AT is a premium, super-fine iron powder characterized by its exceptional purity and high density. Unlike standard sponge irons, IRON325AT consists of solid, dense particles with a spherical-to-irregular shape that provides excellent flow characteristics. With an iron content exceeding 99% and very low impurities, this powder is the top choice for high-precision applications where chemical purity and consistency are paramount.
Due to its high density (~3.0 g/cm³) and "free-flow" nature, it packs efficiently into molds and mixtures, making it a superior candidate for cold casting and high-end manufacturing processes.
Common Uses of IRON325AT
IRON325AT is versatile and widely used in industries requiring high-performance materials, including:
- Cold Casting & Art: The preferred choice for casting delicate, high-precision small objects where a heavy, metallic feel and ability to polish to a shine are required.
- Food & Cosmetics: Safe for specific food contact applications and use in cosmetic formulations (magnetic masks, makeup).
- MIM & Press/Sinter: Ideal for Metal Injection Molding (MIM) and Press & Sinter (P&S) applications due to its high packing density.
- Magnetic Applications: Used in the production of high-grade magnetic paints and soft magnetic composites.
- Polymers & Resins: Acts as a high-density filler to add weight and magnetic properties to plastics and rubbers.
