AM60B vs AZ31B
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.
AZ31B
M11311
The most widely used wrought magnesium alloy. Available as sheet, plate, bar, and extrusion. 3% Al + 1% Zn gives good room-temperature strength and ductility with excellent weldability (TIG/MIG). Density 1.78 g/cm³. An alternative to aluminum where weight reduction is critical. Used for aircraft fuselage panels, electronic device housings (laptops, smartphones), lightweight jigs and fixtures, vibration-damping components, and rapid prototyping. Strain-hardened tempers (H24, H26) provide higher strength. DIN: 3.5312.
