DESCRIPTION:
CDA #773 is a high temperature, high strength corrosion resistant alloy that is primarily used for the joining of steel to steel or carbide to steel. Due to the high flow point, we recommend the use of Engelhard Black Flux. Because of the zinc content, it is recommended that the heat cycle is kept to a minimum to prevent any vaporizing of the zinc.
