There are many metal alloys that
can be used for the production of precision metal stampings.
Generally
material is selected for one, or many, of the following characteristics:
 Electrical Conductivity – one
of the main tasks of the product may be to
provide an electrical pathway from the device attached
Thermal Conductivity – stampings
can help to disperse heat from a device.
Strength – stampings
usually need to be durable, withstanding extremes in
temperature and repeated thermal cycling
Formability – metal
stampings often have a built in component that allows
them to hold themselves, or other devices,
in place
until the next stage of the assembly process.
Economy – often
used in large quantities, metal stampings must accomplish their function
rather inexpensively.

Material may be
chosen in the appropriate thickness to match your project.
Depending on the type and function of
the stamping, material may be .006” up to .040”
