How to Prevent Cracking of China Aluminum Strip Roll When Bending?
For many sheet metal processing companies, they will encounter the same problem, that is, the aluminum strip stock will crack after bending or burst during the anodizing process after bending, so how to avoid this problem?
1. Aluminum strip hardness
If the aluminum strip is too hard, it will be easy to crack. The hardness of China aluminum strip roll mainly depends on its alloy and tempers. We usually choose 1xxx, 3xxx and 5xxx aluminum alloy. 6xxx and 7xxx alloys are too hard, which needs annealing to be in O temper.
2. Aluminum strip thickness
For the aluminum strips, we usually only pay attention the width. For example, aluminum strip 3mm is a common specification. But if you like to bend the aluminum strip, you also need to value the aluminum strip thickness. If the aluminum strip is too thick, it will be difficult to bend.
3. The curved R angle
The larger the curved R angle, the easier the bending of aluminum strip. Therefore when you plan to bend aluminum strip, try to increase the R angle.
4. The texture direction
The bending direction should be consistent with the grain direction of the aluminum strip, otherwise, it is easy to bend.
5. For the aluminum strip which needs stretching, if the process is feasible, it is best to bend before stretching, otherwise it will increase the probability of cracking.
