We are using a cyanide based electrochemical etching process to etch tapered tips on a precious metal alloy wire and have discovered that each material lot behaves differently with the same etch process. These material lots will preferentially etch the grains in one lot and varying levels of the...
I am using a tempered stress relieved beryllium copper which has an ultimate strength of 200ksi. I would like to heat the parts to 400 degrees Fahrenheit for a maximum of eight hours (1 work shift) so that I may bend the parts without cracking. Is this temperature going to affect the physical...
