A new type of aluminum lithium alloy developed in the late 1990s of the United States was developed.
2297 Aluminium lithium alloy plate were developed, and its density is 5% lower than that of ordinary aluminum alloy, and its elastic modulus is 8%~10% higher. Mainly used for plate thickness more than 38mm, with excellent anti fatigue performance and good thermal stability, wall, mainly focus on the application direction of 180℃ use frame, beam and plate constructed to withstand large compressive stresses, the maximum thickness of the alloy has reached 150mm.
