5052 aluminum for the AL-Mg alloy aluminum, is the most widely used as a rust-proof aluminum, high strength of this alloy, particularly with Fu anti-fatigue strength: high ductility and corrosion resistance can not be heat strengthened ,, in half work hardening plasticity is still good, when the plastic work hardening is low, good corrosion resistance, good weldability, machinability bad, can be polished. Density: 0.00000272 Material Name: aluminum and aluminum alloy extruded bars (≤150mm, H112, T6, O state) Standard: Range GB / T3880-2006 Features and application: ① 5052 belong to Al-Mg alloy, using a wide range, especially in the construction industry can not do without this alloy is the most promising alloys. Good corrosion resistance, weldability, cold is better, and with moderate intensity. 5052 is the main alloying elements of 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 - housing and so on. ② AL-Mn alloy, is the most widely used as a rust-proof aluminum, high strength of this alloy, especially those with fatigue strength: high ductility and corrosion resistance, heat treatment can enhance plasticity half peening 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 mailboxes, gas or oil pipe, with a variety of liquid containers and other small loads produced by deep drawing parts: wire used to make rivets.
