Magnesium Alloy QE22A vs ZE41A
Magnesium Alloy · grade comparison
Magnesium Alloy QE22A and ZE41A 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 ZE41A, about 39% more; tensile strength follows at 260 MPa (37.7 ksi) vs 205 MPa (29.7 ksi). In exchange, ZE41A is the more ductile: elongation 3.5% versus 3% for QE22A, and QE22A is harder (80 HB vs 62 HB). QE22A runs hotter in service (250°C vs 150°C continuous).
QE22AChoose it when strength drives the design, or when the part sees heat.
ZE41AChoose it when the part is bent, formed or impact-loaded.
QE22A vs ZE41A: 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 ZE41A — frequently asked
Is QE22A stronger than ZE41A?
Yes. QE22A has a typical yield strength of 195 MPa (28.3 ksi) against 140 MPa (20.3 ksi) for ZE41A — about 39% more. Tensile strength is 260 MPa (37.7 ksi) vs 205 MPa (29.7 ksi).
Which is cheaper, QE22A or ZE41A?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, QE22A or ZE41A?
ZE41A. Its weldability rates very good (70/100) against good (65/100) for QE22A.
