For a high strength hard aluminum, heat treatment can be strengthened, in the annealing, quenching and thermal state of plasticity, spot welding is good, with gas welding and argon arc welding aluminum tube has a tendency to form intergranular crack; The aluminum tube has good machinability after quenching and cold hardening, and is poor in annealing condition. Corrosion resistance is not high, often using anodic oxidation treatment and painting methods or surface cladding aluminum layer to improve corrosion resistance. can also be used as mold material.Aluminum (AL) is a light metal, its compounds in the natural distribution of a wide range of aluminum in the Earth's crust is about 400~500 billion tons, second only to oxygen and silicon, ranked third.
