Hardness BHN 190

Features and Applications

• A copper phosphorous rod with 2% silver to give improved

ductility and easier flowing characteristics. It is also highly

resistant to corrosion. The rod is self fluxing on copper but a

copper flux is required on brass joints

• Electric motors, hot water cylinders, copper/brass fabrication
