COPPER-PHOSPHOROUS ALLOYS
Code Composition % Melting Range SOL Â LIQ Standard Notes
Ag Cu P Sn °C EN 1044
CuP6   94 6   710-880 CP 203 Copper-copper and copper-brass joints. For joining copper to copper no flux is necessary. Particularly good and clean joints can be obtained by using these alloys along with liquid flux spread through torch flame by vaporizer systems. Alloys with Silver are preferred for joints subject to vibrations. CuP7Sn is also available as flux-coated rod.
CuP7   93 7   710-800 CP 202
CuP8   92 8   710-750 CP 201
CuP7Sn   86 7 7 650-700 CP 302
