5A06 Characteristics 
5A06 Aluminium sheet for the Al-Mg-based Rust-proof aluminum, 5A06 Aluminium sheet with high strength and corrosion stability, in the annealed state and extruded plastic is still good, with air tightness and weld seam welding of plastic still, gas welding and spot welding joint strength of 90 to 95 percent of the matrix strength; good machinability. 
5A06 use ① high magnesium Alloy, in non-heat treatable Alloy in good strength, corrosion resistance, good machinability. Surface appearance after anodization. Good arc performance.5A06 Alloy Alloy main elements of magnesium, has good corrosion resistance and weldability, and moderate intensity. Excellent corrosion resistance make 5A06 Alloy widely used marine uses such as ships, as well as automobiles, aircraft welding parts, metro and light rail, should be strictly fireproof pressure vessel (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration equipment, tower, drilling equipment, transportation equipment, missile parts, armor and so on. 
② 5A06 belong to Al-Mg-based Alloy, using a wide range, especially in the construction industry can not do without this Alloy, it is the most promising of Alloy. Good corrosion resistance, weldability, cold is better, and with moderate intensity. Alloy 5083 is the main element magnesium, has good forming properties, corrosion resistance, weldability, moderate intensity, for the manufacture of aircraft fuel tanks, pipelines, and transportation vehicles, ship sheet metal parts, instruments, lights bracket and rivets, metal products, electrical appliances, such as Shell. 
③ AL-Mn-based Alloy, it is the most widely used as a Rust-proof aluminum, high strength of this Alloy, especially with anti-fatigue strength: high ductility and corrosion resistance, heat strengthened ,, not work hardening in half When the plastic is still good, when the plastic work hardening is low, good corrosion resistance, good weldability, machinability bad, can be polished. Mainly used for high plasticity and good weldability, working in a liquid or gaseous medium low load parts, such as fuel tanks, gasoline or oil pipe, a variety of liquid containers and Other deep-drawing made with a small load parts: wire used to make rivets
