Product Details, Specifications, and Technical Information
C693 brass round bar is a lead free and more corrosion resistant replacement to brass 360. 693 Brass is specifically designed to machine at almost the same rate as free machining brass, but because it is lead free, it will be compliant with state laws that restrict the use of lead in plumbing fittings that come into contact with drinking water. The removal of lead and other harmful chemicals such as Arsenic and Bismuth make this alloy much safer for the environment.
