Colloidal Silica / Alumina Suspensions

Used for final polishing, colloidal suspensions are mixtures of abrasive particles dispersed throughout a chemically aggressive liquid carrier. This combination provides a chemical-mechanical polishing action, resulting in deformation-free surfaces.

0.05µm Colloidal Silica/Alumina

Closer View

A unique mixture of colloidal silica and alumina with a pH of 8.5. The addition of gamma alumina allows improved mechanical polishing when compared to colloidal silica. Used to final polish both ferrous and non-ferrous metals, metal-matrix composites and various non-metallic materials.
