Wrought Magnesium Alloys
Wrought magnesium sheet, extrusion and forgings develop route-dependent texture and anisotropy, so temper, grain direction, formability and corrosion finish must accompany the alloy designation.
01
Definition and boundary
Covers mechanically worked products; excludes casting acceptance and chemistry-only substitution.
Reference information only: final acceptance is controlled by the ordered product specification, condition, dimensions and certified test results.
02
How the material system works
Rolling texture drives directionality.
Extrusion refines grains and raises directional strength.
Temper controls forming and residual stress.
03
Representative grades and systems
| Grade or system | Selection focus | Qualification |
|---|---|---|
| AZ31B-H24 | Use AZ31B-H24 only with its governing product specification and condition. | Confirm the governing product specification, delivery condition, section size and acceptance tests before treating designations as interchangeable. |
| ZK60A-T5 | Use ZK60A-T5 only with its governing product specification and condition. | Confirm the governing product specification, delivery condition, section size and acceptance tests before treating designations as interchangeable. |
| WE43 extrusion | Use WE43 extrusion only with its governing product specification and condition. | Confirm the governing product specification, delivery condition, section size and acceptance tests before treating designations as interchangeable. |
