Granular Cover Flux

Granular Cover Flux is a high-efficiency protective additive designed for non-ferrous molten metals, particularly aluminum and its alloys. Its granular composition ensures even distribution across the molten surface, forming a stable barrier that minimizes oxidation, dross generation, and heat loss. Cast Chem Technology’s Granular Cover Flux offers enhanced fluidity and thermal response, allowing for faster fluxing action and superior metal cleanliness in high-volume foundry operations.

Ideal for use in automated dosing systems or manual applications, this flux delivers consistent protection and promotes effective slag separation. Its controlled melting behavior enables it to absorb impurities, prevent gas pickup, and extend crucible life. With low smoke and minimal residue formation, it ensures safer working conditions and better quality castings. It is particularly favored in processes requiring reduced turbulence and improved surface finish.
