Lead-free brass is a copper alloy primarily composed of copper and zinc, engineered to be free of lead. This environmentally friendly material offers excellent corrosion resistance, machinability, and durability, making it ideal for potable water systems, fittings, and valves. It is compliant with stringent drinking water regulations, providing a safer alternative to traditional leaded brass. The alloy maintains good mechanical properties and can be easily fabricated and soldered, meeting the requirements for a wide range of plumbing and industrial applications.
