2.1030 | CuSn8

CuSn8 belongs to the group of copper–tin alloys and is commonly known as bronze.
The alloy features excellent cold formability, good sliding properties, strong spring characteristics, and high strength.
Its good corrosion resistance makes CuSn8 suitable for many technical applications, but it is not the first choice for components with high machinability requirements.
