Aluminum alloys 7075,60615052 can be stamped and bent, and even have deep drawing positions. The key problem is to choose the state of the material to manufacture the ideal workpiece. For example, 7075 and 606 1, don't choose the state with suffix t for bending and stretching position, but choose O state or H state freely, and the plane punching and bending position of T state have little influence. In 5052, H32/H34 soft state and semi-soft state are selected to solve the problem. All stamping and bending materials must be selected according to the actual production difficulty and product thickness. I hope this solution is useful to everyone.
