How Fe45Mn28Co12Cr15 Alloy Powder Enhances Biomedical and Cryogenic Engineering

Fe45Mn28Co12Cr15 alloy powder is an advanced austenitic alloy engineered for exceptional toughness, non-magnetic behavior, and biocompatibility. Its performance under cryogenic and biomedical conditions makes it a leading material choice for precision components produced via additive manufacturing and powder metallurgy.

Optimized Composition for Non-Magnetic and Cryogenic Use

This alloy combines 45% Fe, 28% Mn, 12% Co, and 15% Cr, providing:

• Full austenitic microstructure at all temperatures

• Excellent mechanical strength below -196°C

• Stable non-magnetic properties in medical and MRI-compatible applications

Its fully stabilized structure resists phase transformation and maintains ductility under thermal cycling.

Biocompatibility and Corrosion Resistance

The high Cr and Mn content delivers strong resistance to:

• Physiological corrosion (saline and bodily fluids)

• Pitting and crevice corrosion in chloride environments

• Oxidation in high-humidity or cleanroom atmospheres

This makes it suitable for surgical tools, orthopedic implants, and MRI-safe components.
