Slag Flux for Copper Alloys

Form: grey to yellowish, fine-grained powder
Reaction temperature: approx. 800°C

The product offered is a slag flux for copper alloys such as bronze, brass, or gunmetal.

The use of slag fluxes to optimize your melt is of enormous importance. Even with small amounts, you can optimize your melt and prevent unwanted miscasts. When used correctly, the slag flux ensures that the melt is degassed and, in a broader sense, also deoxidized. The metal content in the slag is reduced, making the melt more fluid. For zinc-containing alloys, the slag flux prevents smoke development and zinc burn-off by forming an insulating slag.

We therefore recommend its use for every melting operation. For aluminum alloys, special slag fluxes/additives exist that achieve similar effects. For low-melting alloys based on tin, lead, and bismuth, no slag fluxes are required.

Application:

The total addition amount should be about 1% of the mass to be melted. Add the slag flux to the melt at the beginning of the melting process. A small portion can be held back and added to the melt shortly before skimming. For multiple casts, you can add the larger portion of the slag flux to the residual melt in the crucible (so-called ‘furnace bear’).
