CUPROTEX 50 – Special Flux for Foundry

Cuprotex 50 is a special flux for treating brass alloys melted in crucible or reverberatory furnaces. The product forms a protective cover on the bath surface capable to reduce gas absorption and excessive oxidation of the metal during melting.

Cuprotex 50 does not provide oxidising conditions. It reduces Zinc evaporation to a minimum.
