Magnesium Alloy AZ80A vs ZK60A
Magnesium Alloy · grade comparison
Magnesium Alloy AZ80A and ZK60A are both magnesium alloy grades, both high strength mg. Both yield at about 250 MPa — strength does not separate them. ZK60A is the more ductile: elongation 14% versus 11% for AZ80A, and ZK60A is harder (75 HB vs 60 HB). ZK60A runs hotter in service (150°C vs 120°C continuous) and ZK60A conducts heat better (121 W/m·K vs 78 W/m·K). On the shop floor, AZ80A welds better (fair vs poor).
AZ80AChoose it when it will be welded.
ZK60AChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
AZ80A vs ZK60A: 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.

AZ80A vs ZK60A — frequently asked
What is the difference between AZ80A and ZK60A?
Magnesium Alloy AZ80A and ZK60A are both magnesium alloy grades, both high strength mg. Both yield at about 250 MPa — strength does not separate them. ZK60A is the more ductile: elongation 14% versus 11% for AZ80A, and ZK60A is harder (75 HB vs 60 HB).
Which is cheaper, AZ80A or ZK60A?
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, AZ80A or ZK60A?
AZ80A. Its weldability rates fair (45/100) against poor (25/100) for ZK60A.
