C69300 brass is a lead free and more corrosion resistant replacement to free machining 360 brass. This alloy is specifically designed to machine at almost the same rate as free machining brass, but because it is lead free, will be compliant with state laws that restrict the use of lead in plumbing fittings that come into contact with drinking water. Other uses for 693 are: PEX fittings, automotive partes, ball valves, stop valves, electric and electronic equipment parts, and both commerical & residential water faucet parts. With the removal of lead and other harmful chemicals such as Arsenic and Bismuth, this alloy is much safer for the environment than 360.
