Hi all,
I found a cooper seller who can cut the plates for us.C1100 copper.He computationals costs
after weightinging the cutted plates.The other seller I found computational costs with the wasted mertiarials and the costs for cutting is included. He also said there will be a little error of the plates, +0/-0.2mm.I think that will be not a problem.Who can say he can make it without any error,just perfect size.The price is RMB95(about USD15) for each “kilogram”.
But there is still a problem confusing me.The cooper has different “status”,in China,we call it “totally hard” and “half hard”.I think the cooper I bought before was “totally hard”,but this seller only can sell “half hard”.’Half hard”cooper plates can form half-moon shape easily.Anyway,I will buy some and have a try.
best,
Li
