Project Description
W-Pb20
EN 1982 CC497KCuSn5Pb20-C
- A leaded tin bronze alloy with 5% tin and 20% lead.
- The Pb-20 is a copper, lead and tin bronze alloy for use in heavy load applications with little lubrication, in corrosive or dusty environments.
- The closest international standard is the ASTM B505 C94300
- Wisco has a large stock of rectangular bars and round solid and hollow bars with immediate availability.
