Aluminum-magnesium alloy, 5052 aluminum alloy belongs to the Al-Mg system of alloys, the use of a wide range, especially the construction industry can not do without this alloy, is one of the most promising alloys. It has good corrosion resistance, excellent weldability, good cold workability, and medium strength.
The main alloying element of 5052 aluminum alloy is magnesium, with good forming and processing performance, corrosion resistance, weldability, medium strength, used in the manufacture of aircraft fuel tanks, fuel lines, and transportation vehicles, ships, sheet metal parts, instrumentation, street lamps brackets and rivets, hardware, electric - ware shells and so on.
Process performance
1, molding properties
The alloy hot state process plasticity is good. Forging and die forging temperature of 420 ~ 475 ° C, in this temperature range for the deformation rate of > 80% of the thermal deformation. Its cold stamping performance is related to the state of the alloy, the cold stamping performance of the annealed (O) state is good, H32, H34 state is second best, and H36/H38 state is not good.
2,Welding performance
The alloy of gas welding, arc welding, resistance welding, spot welding, seam welding performance is good, two argon arc welding tendency to crystallization cracks. Hard brazing performance is still good, and soft brazing performance is poor. Weld strength and high plasticity, weld strength up to 90% ~ 95% of the strength of the base metal. But the gas tightness of the weld is not, recommended 5A03 alloy for solder, can improve its gas tightness, and can eliminate the tendency to crack.
3,Machining performance
The alloy annealed state of the cutting performance is not good, and cold hardening state improved.
