5052 Aluminium Plate

Description

Aluminium-magnesium alloys also contain a small amount of manganese, chromium, beryllium, titanium, etc. Except for a small amount of solid solution, most of the manganese in the alloy forms Mn Al6. The role of chromium in 5052 aluminium plate is similar to that of manganese, which can improve the resistance to stress corrosion cracking, improve the strength of base metal and weld, and reduce the tendency of welding cracks, but its content generally does not exceed 0.35%.

Process Performance

1. Form-ability

A: The alloy has good process plasticity in hot state. The forging and die forging temperature is 420~475°C, and the hot deformation with a deformation rate of 80% is carried out within this temperature range.

B: The cold stamping performance is related to the alloy state. For example, the cold stamping performance in the annealed (O) state is good.

2. Welding Performance

A: The alloy has good performance in gas welding, arc welding, resistance welding, spot welding and seam welding, and crystallization cracks tend to appear in two argon arc welding. The brazing performance is still good, but the soft soldering performance is poor.

B: The strength and plasticity of the weld are high, and the strength of the weld reaches 90% to 95% of the strength of the base metal. However, the airtightness of the weld is not high. It’s recommended to adopt 5A03 alloy as the solder, which can improve its airtightness and eliminate the tendency of cracks.

3. Machining Performance

The cutting performance of the alloy is not good in the annealed state, but the cutting performance is improved in the cold work hardened state.
