Project Description
W-12
EN 1982 CC483KCuSn12-C
- The W-12 is a bronze with 12% tin.
- The closest international standards are the ASTM B505 C90700 and DIN 1705 CuSn12
- Hard and tough material. High resistance to corrosion, impacts and cavitation. Good performance with high loads and pressures.
- Wisco has a large stock of rectangular bars and round solid and hollow bars with immediate availability.
