The magnesium content of 5A05 alloy is high, although the cold deformation can increase its strength, but the plasticity will decrease. The O state material has higher plasticity, and the plasticity of H * 4 material is moderate. Although the 5A05 alloy has high technological plasticity, cold hardening is fast during cold deformation and should be paid attention to in processing parts.
In aircraft manufacturing, the 5A05 aluminum alloy sheet profile forgings wire is usually used for manufacturing parts, such as welded pipes and liquid containers, which require high process plasticity and corrosion resistance and medium load.
