Product Description

8090 aluminum lithium alloy sheet plate

8090 aluminum lithium alloy sheet plate is a medium strength damage resistant alloy with a density of 10% lower than that of 2024 and 7075 alloy, and its modulus of elasticity is 11% higher than that of the latter. It can be used for situations that require both damage resistance and low density.

The 8090 aluminum lithium alloy sheet plate has a very high low temperature strength and toughness, and the change is also more obvious than that of the conventional high strength aluminum alloy. When medium - strength 8090 alloy products are aged to peak state, they are not changed at high temperature.
