Typically most metals can be formed by the spinning process that are supplied in sheet form. There are 4 basic metal spinning methods which are hand spinning, levered compound spinning, hydraulic assisted and CNC power spinning. We do mostly levered spinning and some hand spinning. We mostly spin aluminum in many alloys up to 1/8″, copper up to .090″, brass up to .090, cold roll and hot roll steel up to 14ga and stainless steel up 16ga. Diameters are from ½″ to 30″. Some companies will spin much bigger but they are very specialized along with companies using CNC or hydraulic assisted spinning machines.
