Common marine grade aluminum elbows models: 1060 aluminium elbow, 6061 aluminium elbow, 6063 aluminum elbow, 6082 aluminum elbow, 5083 aluminium elbow, etc. Here we take the 6061 aluminum elbow as an example to explain its technology and chemistry Composition: 6061 aluminium elbow.
6061 aluminium elbow is a high-quality aluminum alloy produced by the heat treatment pre-stretching process. Although its strength can not be compared with that of 2XXX series or 7XXX series, its magnesium and silicon alloy have many characteristics such as excellent processability and excellent welding Features and electroplating, good corrosion resistance, high toughness and deformation after processing, the material is dense and defect-free and easy to polish, the color film is easy, excellent oxidation and other excellent features.

The main alloying elements of the 6061 aluminum elbow are magnesium and silicon and form the Mg2Si phase. If a certain amount of manganese and chromium are contained, the bad effect of iron can be neutralized; sometimes a small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing its corrosion resistance; and a small amount of conductive material Of copper to counteract the adverse effects of titanium and iron on conductivity; zirconium or titanium can refine grains and control recrystallized texture; and lead and bismuth can be added to improve machinability. Mg2Si solid solution in aluminum, the alloy has artificial aging hardening function. The main alloying elements of 6061 aluminum alloy are magnesium and silicon, with moderate strength, good corrosion resistance, weldability and good oxidation effect.
