5052 aluminum plate performance
5052 aluminum plate is AL-Mg series alloy aluminum plate. Magnesium is the main alloying element in 5052 alloy aluminum plate. It is the most widely used anti-rust aluminum. This alloy has high strength, especially fatigue strength: plasticity and corrosion resistance. High performance, cannot be strengthened by heat treatment, good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, poor machinability, and polishing.
Aluminum-magnesium alloy also contains a small amount of manganese, chromium, beryllium, titanium and so on. Except for a small amount of solid solution, most of the manganese in the alloy forms MnAl6. The role of chromium in 5052 aluminum plate is similar to that of manganese, which improves the resistance to stress corrosion cracking, improves the strength of the base metal and the weld seam, and reduces the tendency of welding cracks, but its content generally does not exceed 0.35%.

Process performance
⑴Forming performance
①The alloy has good hot process plasticity. The forging and die forging temperature is 420~475°C, and the thermal deformation with a deformation rate of 80% is performed within this temperature range.
②The cold stamping performance is related to the alloy state. The cold stamping performance in the annealed (O) state is good, followed by the H32 and H34 states, and the H36/H38 state is not good.
⑵Welding performance
①The alloy has good performance in gas welding, arc welding, resistance welding, spot welding, and seam welding. Crystal cracks tend to appear during two argon arc welding. The brazing performance is still good, but the soft brazing performance is poor.
②The strength and plasticity of the weld are high, and the strength of the weld 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, which can improve its airtightness and eliminate the tendency of cracks.
⑶Machining performance
The cutting performance of the alloy in the annealed state is not good, but it is improved in the cold-work-hardened state.
AL1050A aluminum alloy
What material is AL1050A? AL1050A is industrial pure aluminum, with an aluminum content of 99.5%. The aluminum alloy cannot be strengthened by heat treatment.

Aluminum plate state
1. F: Free processing state, suitable for those without special requirements for work hardening and heat treatment conditions during the forming process products, the mechanical properties of products in this state are not regulated
2. O: Annealed state, suitable for processed products that have been fully annealed to obtain the lowest strength
3. H: Work-hardened state is used to increase the strength of products through work-hardening. After work-hardened, the product can pass through (It is not necessary to go through) additional heat treatment to reduce the strength. The code name must be followed by two or three Arabic numerals
4. W: Solution heat treatment state An unstable state, only suitable for natural aging at room temperature after solution heat treatment
Alloy, the state code only indicates that the product is in the natural aging stage
5. T: Heat treatment state (different from F, O, H) It is suitable for products that have been processed (or not) hardened to a stable state after heat treatment. There must be one or more Arabic numerals behind the T code.
