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. |
