C35300
62% Lead Alloy
C35300 is a high-leaded brass and is known as a free machining brass with good formability. C35300 is more free machining, less formable. Alloy C35300 offers the best combination of machining & formability. The machinability rating is 90%. Alloy C35300 exhibits an excellent capacity for being machined, thread rolled & formed. This alloy has a poor capacity to be hot worked. If cold working or extensive machining is necessary, it is recommended that this be followed by stress relieving at 500 degrees for 1.5 hours to reduce the possibility of stress corrosion cracking.
