I was looking to try out using a pancake die in my hydraulic press & have read a number of places that hard or half hard copper is recommended.
I’m certainly finding that half hard copper is not readily available , except at a premium price.
So my question is -
Is using the standard sold copper ( most suppliers call it “soft”) in 20 or 22 gauge workable, as long as you DON’T anneal it ?
Does it actually have to be the premium " half hard or hard temper" ??
