Laser® EX 50 Plus is a peroxide / sulfuric acid system that replaces bichromate, chromic acid, or nitric-sulfuric acid pickles commonly used for pickling copper, brass, and bronze alloys containing iron, manganese, and /or nickel.
As a pre-pickle, Laser EX 50 Plus is an effective process that quickly dissolves heavy oxides to produce a matte surface that is well suited for subsequent metal plating, soldering, or mechanical polishing.
Laser EX 50 Plus is a concentrated peroxide solution that completely removes oxides, scales, and smuts from copper alloys and restores these metals to their original color. Inhibitors contained in this concentrate serve to minimize attack on the base metal and retard tarnish formation after processing.
