Boric Acid Deoxidizing Casting Powder Flux for Melting Precious Metals

Boric Acid Deoxidizing Casting Powder Flux is a high-grade, super-fine flux that keeps metals cleaner during melts and pours. This flux is ideal for melting, casting, and refining metals such as gold, silver, copper, iron, sterling silver, tin, nickel, and their alloys. By actively reducing oxidation, it helps prevent scale and inclusions that can mar finishes and create costly scrap.

In addition to deoxidizing, this powder works as an antioxidant in soldering, promoting stronger, more reliable joints and longer-lasting connections. This 4-lb package delivers long-lasting performance in busy workshops.

Usage is straightforward across a range of precious and base metals, including gold, silver, copper, nickel, and common alloys. The ultra-fine formulation flows smoothly, coats surfaces evenly, and supports cleaner pours with fewer impurities.
