Melting Point ºC 710

UTS N/mm2 500

Hardness BHN 200

Features and Applications

• A copper phosphorous rod with good electrical conductivity

and corrosion resistance. It is self-fluxing on copper. A copper

flux is required on brass joints

• Artistic foundries and general copper and brass fabrications
