铝合金

The relationship between Zr content and mechanical properties of high strength aluminum alloys was examined, and the strengthening values of several factors were calculated.

研究了高强铝合金的力学性能与Zr含量的关系，计算了合金的各种强化因素值。

Based on the microstructure and properties, the Zn content should be controlled between 9.5% and 11.5%.

综合考虑材料的组织和性能，确定喷射成形7×××系铝合金中的Zn含量应控制在

Compared with the traditional 2000 and 7000 series a-luminum alloys, 1420 Al-Li alloy decreases density by 12% and increases Young's modulus by 8%, and has excellent corrosion resistance and high temperature properties.

1420铝锂合金与传统的2000、7000系列铝合金相比，密度低12%，弹性模量高8%左右，具有优异的抗腐蚀性和高温性能。
