AM60B vs AZ91D
Side-by-side chemical composition and mechanical property comparison.
Overview
AM60B
M10602
High-purity magnesium die casting alloy optimized for energy absorption and ductility. 6% Al content provides a balance between strength and elongation (8-12%), superior to AZ91D for crash-relevant parts. Excellent corrosion resistance through strict Fe/Ni/Cu control. Not weldable. Used for automotive seat frames, steering wheel cores, instrument panel supports, pedal brackets, and wheel components where impact resistance is critical. The ductile alternative to AZ91D. DIN: 3.5662, EN: MC 21230.
AZ91D
M11916
The most widely used magnesium die casting alloy worldwide. High-purity variant (D suffix) with strict Fe, Ni, Cu limits for excellent corrosion resistance. 9% Al + 1% Zn provides good castability, strength, and dimensional stability. Density only 1.81 g/cm³ — 35% lighter than aluminum. Not weldable. Used for automotive transmission cases, engine covers, steering components, laptop and smartphone housings, power tool casings, and camera bodies. The industry standard for Mg die casting. DIN: 3.5912, EN: MC 21120.
