C37700
Forging Brass Alloy
Alloy C37700 possesses excellent machining characteristics. The machinability rating for C37700 is 90% of free cutting brass. Alloy C37700 exhibits an excellent capacity for being hot worked. Best results are obtained between 1200ºF to 1300ºF. This alloy has a poor capacity to be cold worked. If cold working is required, it is recommended that this be followed by stress relieving at 500ºF to reduce the possibility of stress corrosion cracking.
