Carbon Block Brazing
A brazing technique that uses silver solder to join wire ends that are heated between two rectangular electric-heated carbon electrode blocks. The silver solder alloy includes 80 percent copper, 15 percent silver and 5 percent phosphorous. The alloy melts at 640°C (1185°F) and has a flow point of 704°C (1300°F). This process requires no flux to produce optimum brazed joints.
