Analysis of cracking of aluminum plate often encountered

When making or processing aluminum plates or other aluminum products, the phenomenon of aluminum plate cracking is often encountered. What are the reasons for that? Is there any way to prevent it? Harbin Dong Xing Aluminum Co., Ltd is a competent and reliable Aluminum sheet manufacturer china.

1. The hardness of aluminum plate

The hardness of the aluminum plate is too high and it is very easy to crack. This requires a good selection of aluminum materials, mainly to see the trademarks and conditions of aluminum. The 1 series, the 3 series, and the 5 series are usually compared. The hardness of the 6 series and the 7 series is too high to be bent before annealing to the O state. It is also the quality of the aluminum plate, the same type of aluminum plate import material is not easy to crack than the domestic material, but the price of the material is also a lot of expensive.

2. The thickness of aluminum plate
Too thick the aluminum plate is not bending, we want to understand, try to use a little thin aluminum plate.
3. Bends the R angle
The greater the corner of the bending R, the higher the success rate, and the greater the R corner as much as possible. Harbin Dong Xing Aluminum Co., Ltd could provide you with Aluminum coating sheet 5052.

4. Aluminum plate texture direction
The direction of bending should be straight and not parallel to the direction of the aluminum plate.

5. The aluminum plate parts of the demand drawing 
In the case of the working procedure, the best is to bend after the bending, otherwise the probability of bending and cracking will be added.

The continuous promotion of aluminum plate has become a new growth point for the consumption of aluminum alloy. At present, China's aluminum product is casting Aluminum Alloy primary ingot, although in recent years, recycled aluminum liquid aluminum and the downstream automotive parts manufacturing on the direct supply mode has been rapid development, but nature does not expand the types of recycled aluminum products, regeneration of high-end deformation Aluminum Alloy is still at the exploratory stage.

Therefore, it will be the future development direction for the regenerated aluminum industry to broaden the type of recycled aluminum products by continuing scientific and technological innovation of the regenerated aluminum industry. With the development of science and technology, the application of aluminum sheet is more and more extensive. Aluminum plates are also used in automobile and aircraft manufacturing industry, and aluminum plates will also be applied to more industries in the future.
