Cover flux

Cover Flux is a specially formulated metallurgical additive used in non-ferrous metal casting to protect molten metal from oxidation and atmospheric contamination. It creates a protective layer on the molten surface, minimizing dross formation and heat loss while enhancing metal quality. Cast Chem Technology’s Cover Flux is engineered for high thermal efficiency and low smoke emission, ensuring a cleaner working environment and more consistent casting results. Suitable for aluminum and its alloys, our flux ensures smoother operations, reduced inclusions, and improved surface finish.

Designed for optimal coverage and reactivity, Cast Chem Technology’s Cover Flux plays a vital role in refining metal by absorbing non-metallic impurities and facilitating easy slag removal. Its uniform spreading behavior ensures complete surface protection, even in turbulent melts. With excellent flow characteristics and low residue formation, this flux contributes to extended crucible life, reduced rework, and improved metallurgical cleanliness. Whether in manual or automated casting setups, it delivers consistent performance and is trusted by foundries for its reliability and cost-effectiveness.
