High-Strength, Heat-Resistant Magnesium Rare-Earth Alloy


VW94 alloy is a high-strength, heat-resistant magnesium alloy based on the magnesium-gadolinium-yttrium-zirconium system. Typically processed through age/ solution treatment followed by aging, it is primarily used for manufacturing rolled sheets and forged components. At room temperature, its tensile strength and yield strength, as well as its high-temperature transient strength, all outperform those of the high-strength, heat-resistant magnesium alloy WE43. The alloy achieves a room-temperature strength exceeding 400 MPa and can withstand temperatures up to 350°C, making it currently one of the magnesium alloys with the best-reported mechanical properties.

Primarily used in aerospace, aviation, and defense applications where there is a strong need for weight reduction and where components must withstand extreme temperature fluctuations—such as cockpit frames, nose cones, door frames, ribs, beams, missile pylons, missile compartments, engine casings, cylinders, and gearbox housings, among other parts.
