Mechanical properties of Mingtai Aluminum 5052 aluminum allo

Edit:Mingtai Date: 2019-05-27 15:57
The 5052 aluminum alloy belongs to the Al-Mg alloy and has a wide range of applications. Especially in the construction industry, it is inseparable from the alloy and is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability and medium strength. The main alloying element of 5052 aluminum alloy is magnesium, which has good forming and processing properties, corrosion resistance, weldability and medium strength. It is used in the manufacture of aircraft fuel tanks, oil pipes, and sheet metal parts for transportation vehicles and ships, instruments and street lamp brackets. Rivets, hardware, electric-shells, etc.
Mechanical properties of 5052 aluminum alloy
(1)
1 The alloy hot state process is good plasticity. The forging and die forging temperatures are 420 to 475 ° C, and the deformation rate is >80% thermal deformation in this temperature range.
2 The cold stamping performance is related to the alloy state. The cold stamping performance in the annealing (O) state is good, the H32 and H34 states are second, and the H36/H38 state is not good.
(2) Welding performance
1 The alloy has good gas welding, arc welding, electric resistance welding, spot welding and seam welding, and there is a tendency of crystal cracks during the argon arc welding. The brazing performance is good and the soldering performance is poor.
2 The strength and plasticity of the weld are high, and the weld strength is 90%~95% of the strength of the base metal. However, the airtightness of the weld is not high. It is recommended to use 5A03 alloy as the solder to improve the airtightness and eliminate the tendency of cracks.
(3) Machinability
The alloy has an inferior machinability in the annealed state and an improvement in the cold hardening state.
