CoCr Cleaner is an acidic bath used for cleaning and deoxidizing cobalt/chromium alloys to render them suitable for medical and aerospace applications. It removes weld or laser scale leaving a brilliant finish, without hydrogen embrittlement or halide-induced stress cracking. CoCr Cleaner will attack base metal very slowly, and in the process polish the metal. CoCr Cleaner may also be used as a chemical polish for 300 series stainless steel. It is more reactive towards stainless steel than on CoCr.
Alkaline Descale is a strongly oxidizing surface conditioner designed to descale cobalt/chromium and other chromium based alloys before chemical polishing or electropolishing using CoCr Cleaner (RDZ-1881) or ElectroPolish Ti2 (RDZ-1676), respectively. It will convert insoluble oxides to soluble forms and thus assure uniform subsequent processing. Alkaline Descale is provided in two parts, A and B.
