C69300 - ECO BRASS
HIGH PERFORMANCE LEAD-FREE BRASS
Atlas carries
C69300 ECO Brass Rounds and Hex Bar. We will cut the material to length if required. This alloy is ideally suited for high-performance lead-free applications. Its machinability rating of 85, so it is not quite as easy to machine as C36000. Its rated good for welding, brazing, and soldering. Its excellent in hot forming, but I wouldn't go cold working it any time soon. This material is compliant with the Federal Safe Drinking Water Act.
