Magnesium Alloy Ingot WE43A Mg Master Alloy Best Quality With ASTM Standard Production Magnesium WE43
WE43 is a high strength Magnesium Alloy which offers good mechanical properties both at ambient and elevated temperatures.The alloy mainly contains yttrium and neodymium. WE43 can be used successfully in temperatures up to 300°C and benefits from good corrosion resistance. The alloy is an excellent engineering solution in applications where weight reduction without compromising performance is required. Motorsport therefore is an obvious beneficiary as is the aerospace sector.

Heat treatment
WE43 castings requires the material to be solution treated for 8h at 525°C (977°F). Then air cooled. It can be hot water quenched as well. It can be aged for 16h at 250°C (482°F). After these processes, the material has to be air cooled.
Welding
WE43 can be welded using tungsten arc inert gas process. A filler rod of similar composition should be used.
Machining
WE43 can be easily machined using high powered tools and speed.
Applications:
Missiles
Powertransmissions
Aircraft engines
Motorsport
Helicopter rotor heads
Engine casings
Racing wheels
Gear box casings
