Copper question
Copper question
(OP)
Hi,
Ive been making bike bells from 1.5mm thick 60mm copper discs and normally they ring very loud and for quite a period of time however I just got a new batch of discs and they dont ring and basically make a thud! I ordered the discs from the same laser cutting firm and both times its been C106 copper sheet. The brass and steel discs I ordered ring the same as previously
Could someone explain to me what is going on?
Steven

RE: Copper question
1. Wrong alloy
2. Wrong condition, Were these a lot softer than the usual ones?

RE: Copper question
Is it the hardness that's the issue? I'll try to get full hard in that case
RE: Copper question
I am not sure how much the damping factors change with cold work, but the initial tone should be the same.
