Magnesium Alloy AM60A vs AM60B
Magnesium Alloy · grade comparison
Magnesium Alloy AM60A and AM60B are both magnesium alloy grades. Both yield at about 130 MPa — strength does not separate them. AM60B is the more ductile: elongation 8% versus 7% for AM60A.
AM60BChoose it when the part is bent, formed or impact-loaded.
AM60A vs AM60B: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all magnesium alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

AM60A vs AM60B — frequently asked
What is the difference between AM60A and AM60B?
Magnesium Alloy AM60A and AM60B are both magnesium alloy grades. Both yield at about 130 MPa — strength does not separate them. AM60B is the more ductile: elongation 8% versus 7% for AM60A.
Which is cheaper, AM60A or AM60B?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, AM60A or AM60B?
AM60B. Its weldability rates fair (40/100) against fair (35/100) for AM60A.
