YAL-766BB polishing compound is suitable for electrolytic polishing of various precision aluminum and aluminum alloy parts. Treated workpieces achieve a mirror-like finish while effectively removing burrs, burrs, mechanical marks, and residual metal ions from surface processing. Electrolytic polishing can be performed directly after degreasing CNC machining, replacing a series of processes such as grinding, polishing, alkaline etching, and acid etching. The YAL-766BB electrolytic polishing process is simple and practical. It is a superior process compared to traditional alkaline etching and tri-acid polishing, as it does not contain nitric acid and produces no toxic gases.
