Overview

This flux is intended for bullet casters who want a cleaner, more controlled melt during alloy preparation. It is described as reducing dross formation and improving the fluidity of bullet alloys, while remaining non-smoking, non-fuming, flameless, and odorless. The formula is also noted as non-corrosive, which helps keep iron and steel equipment free from rust and casting pots cleaner over regular use. For hunters and reloaders who cast their own bullets, it offers a straightforward option for maintaining a more orderly casting setup without adding strong odors or visible smoke.
