Flux for melting copper.

Copper and chromium copper should be melted under a floating flux cover to prevent both oxidation and the pickup of hydrogen from moisture in the atmosphere. Copper is one stubborn metal that has a high melting point reaching up to 1 085 c. Copper processing copper processing roasting smelting and converting. For cleaning gray and ductile iron ladles.

Alucoflux yb melting cover for copper zinc alloys containing over 8 0 zinc. In the case of copper crushed graphite should cover the melt. Keeps melting unit clean. This flux reduces metal oxidation promotes separation of dross from metal and reduces gas levels in the melt.

The conventional way of melting copper is through the use of large scale equipment for mass producing great quantities of copper such as induction furnaces and foundries. They are used in both extractive metallurgy and metal joining. In older processes the concentrate containing between 5 and 10 percent water is first roasted in a cylindrical refractory lined furnace of either the hearth or. Fluxes may have more than one function at a time.

It is manufactured by synex inc. The addition of flux provides a very desirable solution to this problem. With chromium copper the cover should be a proprietary flux made for this alloy. We also have pre mixed standard refining flux hank chapman flux flux thinner and many more special recipes for all of your melting applications.

Some of our individual flux components include. This flux is adapted to ores that may be classified as average but is so compounded as to allow the addition of. Bcs brass casting flux is a professional grade cover and drossing flux for use in brass bronze copper melting. Reduces zinc loss reduces fuming.

Alucoflux gb melting cover flux for copper and bronze alloys. Assists with slag free casting by lowering the melting point and viscosity of the slag and allowing it to rise to the surface for skimming. If the ore from which gold is to be separated out contains elements and impurities with a high melting point. Once a concentrate has been produced containing copper and other metals of value such as gold and silver the next step is to remove impurity elements.

The process becomes highly energy intensive as high temperatures are required to get the mixture melted down. Some of the earliest known fluxes were sodium carbonate potash charcoal coke borax lime lead sulfide and certain minerals containing phosphorus. Fluoride containing gray and ductile iron ladle flux. Anhydrous borax boric acid assay dense soda ash assay silica fluorspar potassium carbonate manganese dioxide and more.

This does not include the manganese bronze alloys. Gold smelting flux lowers smelting point.
