The 2.1090 bronze alloy (CuSn7ZnPb) is known for its excellent sliding properties and reliable emergency running capabilities. This material is composed of copper as the main element, with tin, zinc, and lead. It offers medium hardness, outstanding machinability, and strong corrosion resistance, including in seawater environments. The alloy is also resistant to non-oxidizing acids and neutral salt solutions. It is not well suited for welding but can be soft soldered and polished electrolytically. Its brazeability and mechanical polishability are rated as medium.
