It is inevitable to intentionally add lead to copper and zinc in order to obtain the excellent machinability. C6801/C6802 is an epoch new alloy, which adds Bismuth (Bi) in replacement of lead to reduce the use of hazardous substance to the environment while accomplishing the excellent machinability.
Bismuth (Bi) has always been a heavy metal substance that has extremely small impact on the human body and the environment, which has been widely used in the livelihood supplies.
