The 2.1090 bronze alloy, also known as CuSn7ZnPb, is a reliable sliding material known for its excellent emergency running properties. Composed primarily of copper, with tin, zinc, and lead, this alloy offers moderate hardness, outstanding machinability, and strong resistance to corrosion—even in marine environments. It withstands non-oxidizing acids and neutral salt solutions, though its weldability is limited. CuSn7ZnPb can be soft soldered and electrolytically polished with ease, while its suitability for brazing and mechanical polishing is moderate.
