CUZN37PB1SN1 Naval Brass

Naval Brass Pipe / CUZN37PB1SN1 Naval Brass

CuZn37Pb1Sn1 Naval Brass is a leaded and tin-bearing copper-zinc alloy known for its excellent corrosion resistance, good machinability, and reliable mechanical strength. The addition of tin enhances resistance to seawater and dezincification, making it suitable for marine and industrial environments. It is widely used in fittings, valves, fasteners, hydraulic components, and fluid handling systems that require durability and long-term performance.
