CUPROTEX 12 – Special Flux Copper

Cuprotex 12 is recommended when is necessary to reduce the content of sulfur in copper alloys. The presence of sulfur affects alloy’s ductility and tensile strength, even if the content is lower than 0.01%.  The removal of sulfur contributes to produ­ce castings with lower porosity, with higher tensile strength and reduces problems of leakage under pres­sure.
