Forming Issues

I've got a set up to do some forming in which a piece of metal becomes a u Shape. We used to use a Galvaneal material but due to lead issues we can no longer get it. so we've been trying other materials

issues we've seen and are a little baffled by is a an .022 galvanized sheet metal and a .048 CRS form the same and as we would expect.

But a draw quality material of .048 thickness won't hold the shape and has a lot of spring back.

Just curious for a little background data on forming and the differences in draw quality material, vs CRS, vs Galvanized.

Thanks for the help!

RE: Forming Issues

You'll have to find out exactly what alloy and temper you got when you ordered 'draw quality'.

My guess is that maybe you got an alloy that's 'bake-hardenable', and that it's been stored in the sun.

I agree with Mike the matl is most likely work harden.
therefore more spring back.
request certs on your material, look up the data sheets, is it formable?
