Aluminum turning parts-Automatic turning

This is a small piece of aluminum like a bowl, which is also made by automatic turning. Its size is very small and its outside diameter is only 6mm. It is obviously not for eating.
The material grades currently available for aluminum turning parts are: T6 6061 6063 hard aluminum, 7075 hard aluminum, 5056 normal aluminum rod
By the way, the 2021 aluminum rod, a kind of aluminum with relatively low hardness and relatively poor mechanical properties, is not recommended by our company for customers.
