Deep drawing has always presented a problem in maintaining the smooth surface of sheet in particular with stainless steel.
Metalminotti copper alloys have been very successful in stainless steel deep drawing, thanks to their high hardness and low coefficient of friction. This permits to obtain perfect surfaces of the finished item, avoiding any seizure problems during drawing. Moreover, the low friction coefficient allows to increase the drawing depth thus boosting the production. A longer service life is assured for all items of deep drawing equipment.
The mechanical hardness of these alloys is not the result of a surface treatment, but it’s caused by the homogeneous material from the centre to the surface.
Some of Metalminotti deep drawing products:
- Blank holders
- Forming dies
