The 2.1090 bronze alloy is known for its excellent emergency running properties and sliding capabilities. Composed of copper, tin, zinc, and lead, this material offers medium hardness, outstanding machinability, and strong corrosion resistance—even in marine environments. It withstands neutral salt solutions and non-oxidizing acids, though it has limited weldability. CuSn7ZnPb can be soft soldered and is suitable for electrolytic polishing, while its brazing and mechanical polishing properties are moderate.
