What metals can be deep drawn? Professor Metal explores metal alloy selection for deep drawing, addressing tooling costs, finish, and deep draw percentages.
Do you have a choice or does design call for a particular alloy?
Aluminum is a good material. It is light yet strong, It is easily worked (drawn); readily accepts a host of finishes; can be washed and shipped in an as-fabricated condition without rusting and has a pleasing appearance. Tooling for aluminum is less expensive than steel.
Mild low carbon steel in the annealed condition that is of good deep draw quality can be drawn quite easily (tensile in “O” temper 45000 PSI). There are an infinite variety of other steel alloys that can be drawn in their “O” temper then heat treated for strength:
THINGS TO CONSIDER:
Other common metals that can be successfully drawn are: copper, brass and stainless steel?
The same approximate draw percentages used for steel and aluminum can be used for these metals.
