The 2.1090 bronze alloy, also known as CuSn7ZnPb, is a high-quality sliding material valued for its reliable emergency running properties. Comprised mainly of copper with additions of tin, zinc, and lead, this alloy offers medium hardness, excellent machinability, and strong corrosion resistance, including in seawater environments. It stands up well to non-oxidizing acids and neutral salt solutions, though it has limited weldability. CuSn7ZnPb is suitable for soft soldering and electrolytic polishing, while its brazeability and mechanical polishability are moderate.
You can conveniently order bronze rods from Evek GmbH. We also offer other bronze alloys at competitive prices.
