5A02 aluminum alloy sheet profile forgings wire

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 700~750℃, and the casting temperature is 690~730℃. 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.
