Common problems in the production of 5052H32 aluminum plates
The biggest use of 5052 aluminum plates is for appearance parts or electronic accessories. Henan Mingtai Aluminum produces 5052 aluminum plates. The 5052 aluminum plates produced are complete in specifications, including 5052h32 aluminum plates, 5052h34, and 5052-o. The specifications are complete. The 5052 aluminum plates produced by Mingtai Aluminum have a thickness of 0.3-500mm and are widely used in trolley cases, fuel tank materials, LCD backplanes, tank materials, door panels, high-voltage switch housings and other fields.
Henan Mingtai Aluminum 5052h32 aluminum plate manufacturer has been deeply involved in the aluminum processing industry for 20 years. It is understood that there are often some problems in the production of 5052 aluminum plates on the market. Analyze the problems of 5052 alloy aluminum plates and propose feasible methods.
5052-h32 aluminum plate introduction
5052h32 aluminum plate belongs to Al-Mg alloy, which is a widely used rust-proof aluminum. This alloy has high strength, especially fatigue strength: high plasticity and corrosion resistance, cannot be strengthened by heat treatment, good plasticity during semi-cold hardening, low plasticity during cold hardening, good corrosion resistance, good weldability, poor machinability, and can be polished.
The performance advantages of 5052-h32 aluminum plate produced by Mingtai:
1. Used for high plasticity and good weldability
2. Good plasticity during semi-cold hardening
3. Low plasticity during cold hardening
4. Good corrosion and good weldability
5052-h32 aluminum plate is used in the field of automotive aluminum: automotive engine outer panel, bus luggage compartment panel, bus anti-slip decorative panel, automotive fuel tank aluminum plate, etc.
There are three common problems with 5052 alloy aluminum plates.
1. Surface defects on 5052 aluminum plates
The surface problems of 5052h32 aluminum plates, except for individual cases related to the blank, are mostly caused by the various machine trains during the production process.
2. 5052 alloy aluminum plates have color difference, black silk, sand holes and other defects after oxidation
There are many reasons for the black silk of 5052 alloy aluminum plates, such as the rolling oil dripped from the auxiliary machine train due to poor management, and the indentation caused by excessive pressure or tension on the plate surface. If the thin material is rolled, these dark marks will become thinner and thinner, forming dark lines or black lines. Sometimes it is even difficult to distinguish whether it is oil or marks, and there is no color difference on the surface at all, but it is very obvious after oxidation. For customers, seeing the inconsistent appearance, they must refuse. The appearance of black silk after oxidation of 5052h32 aluminum plates is the most fatal. Once this happens, there is almost no room for survival, and the losses and consequences brought are irreparable. Secondly, color difference is not allowed for products with appearance. No customer is willing to accept products with “two-faced” characteristics. To eliminate these problems of 5052h32, 5052 aluminum plate manufacturers still have to rely on the source machine series to control.
Reasons for sand holes: Sand holes are generally caused by internal structural problems. When casting billets, impurities or water vapor are not removed cleanly, or other elements are not mixed evenly. Therefore, it is required to control and detect the source link of ingot casting.
3. Performance requirements of 5052 aluminum plate: tensile strength, hardness, elongation, bending requirements, etc.
As for the performance problems of 5052h32 aluminum plate, the most common one is bending deformation. This link cannot be generalized because of the different uses of customers’ products, but generally in the annealing link, how much temperature, how long, how thick to anneal, there are standards.
