Bright Dipping
The phosphoric acid/nitric acid chemical polishing bath (bright dip) is widely used to produce specular finishes on a variety of aluminum alloys used for automotive, appliance, and architectural trim.
Caustic Etch
Caustic etching before anodizing reduces these variations and makes the appearance of the aluminum surface more attractive to the customer.
Cleaning of Aluminum Prior to Anodizing
The cleaning step which begins the journey of aluminum metal through the anodizing process is extremely critical to the success of the rest of the system.
