High Strength Cast magnsium alloy billet WE43 produced by HIGH BROAD

WE43B is a high strength cast magnesium alloy, the applicable temperature can reach 300 ℃. The alloy at high temperature without the use of silver or thorium can retain its good mechanical properties.

The alloy has long-term exposure to temperatures up to 250 ℃ when the performance is very stable. WE43B has a particularly good corrosion resistance.
 

Application:The alloy retains high performance at high temperatures and is of interest to aircraft engine designers and other powertrain, helicopter transmissions, missiles, racing cars and high performance vehicles.
