AMS 4439 Alloy ZE41
ZE41 is a well proven magnesium casting alloy containing zinc, rare earths and zirconium. Used in the T5 condition, this medium strength magnesium alloy is ideal for high integrity castings operating at ambient temperatures or up to 300°F. In addition to displaying excellent casting characteristics, the alloy is both pressure tight and weldable.
AMS 4439 ZE41 Applications:
The proven versatility of this alloy makes it of interest to a wide range of designers dealing with aerospace, automotive, military and electronic applications. Castings in ZE41 are found in a wide range of applications including: Helicopter gearboxes, Performance car components, Video cameras, Military equipment, Computer parts, Aircraft engines, Power tools, Vibration testing equipment, Aircraft components, and Motorcycle wheels.
AMS 4439 ZE41 Weldability:
Weldable by the TIG process with filler rod of a similar composition. Castings should be heat treated after welding.
