5083-H112 precision aluminum tube is a high magnesium alloy with good strength, corrosion resistance and machinability among non-heat treatable alloys. The surface is beautiful after anodizing. Arc welding performance is good. The main alloying element in 5083 precision aluminum tube is magnesium, which has good corrosion resistance and weldability, as well as medium strength. Good corrosion resistance, good cold workability, and moderate strength.
5083 precision aluminum tube is an AL-Mg alloy aluminum plate, which is the most widely used anti-rust aluminum. This alloy has high strength, especially fatigue resistance: high plasticity and corrosion resistance, and cannot be strengthened by heat treatment. It has good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, and poor machinability. O state).
