High strength
A20X™ is the strongest aluminium casting alloy with typical mechanical properties of A20X™ cast parts up to 475MPa UTS, 415MPa yield and 3% elongation.
Fatigue
The A20X™ casting alloy offers fatigue properties equivalent to 7050 series wrought aluminium – far superior to any other aluminium casting alloy.
Temperature
The A20X™ casting alloy can produce parts that can operate at temperatures at least 50 degrees higher than the limits of conventional aluminium casting alloys.
