Magnesium Alloy QE22A vs ZM10
Magnesium Alloy · grade comparison
Magnesium Alloy QE22A and ZM10 are both magnesium alloy grades. QE22A is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 140 MPa (20.3 ksi) for ZM10, about 39% more. QE22A is the more ductile: elongation 3% versus 2.5% for ZM10. QE22A runs hotter in service (250°C vs 130°C continuous) and QE22A conducts heat better (113 W/m·K vs 72 W/m·K). On the shop floor, QE22A welds better (65 vs 55 out of 100) and ZM10 sits in a lower cost tier (premium, $$$) than QE22A (high, $$$$).
QE22AChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ZM10Choose it when cost is the deciding factor.
QE22A vs ZM10: 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.

QE22A vs ZM10 — frequently asked
Is QE22A stronger than ZM10?
Yes. QE22A has a typical yield strength of 195 MPa (28.3 ksi) against 140 MPa (20.3 ksi) for ZM10 — about 39% more. Tensile strength is 260 MPa (37.7 ksi) vs 260 MPa (37.7 ksi).
Which is cheaper, QE22A or ZM10?
ZM10 is the lower-cost material: it sits in the premium tier ($$$) while QE22A is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which welds better, QE22A or ZM10?
