5A02/5A03/5A05 Aircraft Aerospace Aviation Aluminium Extrusion Profiles for Sale
5A02 alloy with low strength, high plasticity, cold deformation can improve its strength, but will reduce the plasticity, have good mixing performance in welding hydrogen welding, welding and friction contact, can also be welding, high corrosion resistance. The welding of medium load in aircraft manufacturing requires high technological plastic and corrosion resistant parts, such as pipes, liquid containers and slippery frames.
The melting temperature of 5A02 is 700~750ºC, and the casting temperature is 690~730ºC. Alloy wires are used as solders and rivets. The machinability of 5A02 O is not good, and it is improved in the condition of cold hardening. The 5A02 surface treatment process is equivalent to other aluminum alloys, but it is much worse than the 6063 alloy.

5A03 aluminium alloy sheet profile forgings is an alloy with moderate Mg content in 5 * * * system, with low strength and high plasticity. Cold deformation can improve its strength, but the plasticity will decrease. In aircraft manufacturing, we need to manufacture welded medium load parts, such as pipes, liquid containers and skeletons, which need high technological plasticity and high corrosion resistance.
The melting temperature of 5A03 is 700~750 ºC, and the casting temperature is 690~730ºC. 5A03 alloy has quite high corrosion resistance. The die forging temperature of 5A03 is 420~475ºC, and the deformation rate in this temperature range is more than 80%. 5A03 alloy wire does not form weld when it is made of solder, and the strength of the weld can be 90%~95% of the matrix material, and it has high plasticity at the same time. The machinability and grinding performance of the O state material are not good, and the H state material is better.

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.
