AM50A Magnesium vs. AM60B Magnesium
Both AM50A magnesium and AM60B magnesium are magnesium alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 99% of their average alloy composition in common.
For each property being compared, the top bar is AM50A magnesium and the bottom bar is AM60B magnesium.
