The development trend of aluminum alloy is the pursuit of high purity, high strength, high toughness and high temperature resistance. Aluminum alloy used in military industry are mainly aluminum lithium alloy, aluminum copper alloy and aluminum zinc magnesium alloy. The new aluminum lithium alloy used in the aviation industry, the aircraft is expected to decline in weight by 8% to 15%; aluminum lithium alloy will also be a spacecraft and thin-walled missile shell candidate structural material. In order to meet the rapid development of the aerospace industry, the research focus of aluminum-lithium alloy in Mingtai Aluminum R & D department is still to solve the problem of poor toughness in the thickness direction and cost reduction.

Mingtai Aluminum major military products alloy: 2017, 2A14, 2A12, 2024, 7050, 7075, 5A05 and so on.
