Brightening and passivation of copper and its alloys

Manufacture and Machining can result in tarnishing and oxidation occurring on the surfaces of copper and copper alloys.

The brightening treatment ‘revives’ such surfaces by eliminating the impurities and the sequent passivation treatment slows down the oxidation process caused by atmospheric agents.
