Iron/Chromium/Aluminium Alloy Spherical Powder (Fe81/Cr16/Al 3) comes in 14 variations that provide a range of material properties. The spherical morphology of its powder particles makes it useful for industrial applications like metal injection molding to create intricately shaped parts. At the same time the addition of chromium and aluminium to iron allows this alloy powder to achieve high strength, hardness and corrosion resistance.
