Common combinations include:
Steel backing + bronze lining
Steel backing + copper-lead alloy
Steel backing + aluminum-tin alloy
They are typically made through sintering, bonding, and precision machining processes to ensure strong metallurgical adhesion between the two layers.
A gunmetal flange is a pipe-fitting component made from gunmetal (a bronze alloy of copper, tin, and zinc) used to connect pipes, valves, pumps, and other equipment.
Because of their superior resistance to corrosion, especially in marine and wet environments, and their long service life under pressure and temperature variations.
