When manufacturing or processing aluminum plates or other aluminum products, cracking of aluminum plates is often encountered. What is the reason? Is there any way to prevent it?
1. Hardness of aluminum plate
The hardness of the aluminum plate is too high and it is easy to crack. This requires choosing a good aluminum material, mainly based on the trademark and conditions of the aluminum. Usually compare 1 series, 3 series and 5 series. Series 6 and 7 are too hard to bend before being annealed to the O state. This is also a quality problem with aluminum plates. Imported materials of the same type of aluminum plates are less likely to crack than domestic materials, but the price of the materials is also much more expensive.
2.Thickness of aluminum plate
An aluminum plate that is too thick is not curved. We need to understand and try to use a little aluminum sheet.
3. Bend R angle
The larger the bending angle R, the higher the success rate, and the larger the R angle, the better. Harbin Dongxing Aluminum Co., Ltd. can provide you with aluminum coated plate 5052.
4. Aluminum plate texture direction
The direction of the bend should be straight, not parallel to the direction of the aluminum plate.
5. Aluminum plate parts requiring drawings
In the case of process, it is best to bend after bending, otherwise it will increase the possibility of bending and cracking.
The continuous promotion of aluminum plates has become a new growth point for aluminum alloy consumption. At present, my country's aluminum alloy products are the main ingots of cast aluminum alloys. Although the direct supply method of aluminum recycling liquid aluminum and downstream auto parts manufacturing has developed rapidly in recent years, the types of recycled aluminum products have naturally not been expanded. High-end deformed recycled aluminum alloys are still in the exploratory stage.
Therefore, the recycled aluminum industry will continue to expand the types of recycled aluminum products through technological innovation in the recycled aluminum industry, which will be the future development direction. With the development of science and technology, aluminum plates are used more and more widely. Aluminum plates are also used in the automobile and aircraft manufacturing industries, and they will be used in more industries in the future.
