Leaded Bronze
Leaded Bronzes and Gunmetals usually provide a good balance of corrosion resistance and strength whilst offering better machining characteristics than other Bronzes. The substantial lead content of the material gives it excellent machining qualities with medium strength and good pressure tightness. It is also not subject to dezincification. Leaded Gunmetal LG2 is a general-purpose leaded gunmetal that conforms to the requirements BS1400 – 1985 alloy LG2. LG2 has excellent resistance to superheated steam applications and has reasonable corrosion resistance to brine and seawater. This makes it the perfect fit for pressure-tight pump and valve components, pump impellers, fittings and general engineering applications.
