C69300 Lead Free Brass
As of January 4, 2014, the Safe Drinking Water Act (SDWA) requires drinking water products sold or installed for use in public water systems, as well as plumbing in facilities, to meet a weighted average of not more than 0.25 percent lead. The states of California (AB1953), Vermont (S152), Maryland and Louisiana have already instituted these requirements for products currently in the market.
C693 Lead-Free Brass has excellent dezincification corrosion resistance and excellent stress corrosion cracking resistance. One if its unique features is that it is corrosion resistant to chemicals found in water and gas. It has high strength equivalent to stainless steel. It also has good machinability, excellent hot forgeability, easily accepts solder and brazing, and has excellent polishing and plating capabilities. C69300 Lead-Free Brass is compliant with the Federal Drinking Water Act, and it also support applications following the U.S. EPA standards for antimicrobial performance.
