Also, the grades of metals we're using for metal spinning are not easily obtainable and differ from the grades used in rolled/welded shells. That's the case with our medium manganese steel, but our aluminum, brass and copper are obtained in special grades as well.
Brass and copper are also annealed before and during the process of metal spinning.
