Product Details
Rolled板材 almgcu22
Extruded板材
WE43 is one of the most successfully developed commercial rare-earth magnesium alloys to date, capable of operating at temperatures up to 250°C while delivering outstanding mechanical properties at both room and elevated temperatures, along with a relatively balanced material cost. At room temperature, its tensile strength reaches as high as 350 MPa, and even at 300°C, it still maintains a tensile strength of 170 MPa—making it well-suited to meet the performance demands of diverse applications, including helicopter transmission systems, rail transit power systems, aerospace engines, missile manufacturing, and medical-grade materials.
