Anodizing is an electrochemical process that increases the wear resistance of all metal parts. Anodizing creates a hard coating that is great for many applications. Anodizing is a prominent finishing process in the medical and aerospace industries. Anodizing is a method of increasing the corrosion resistance of a metal part by forming a layer of oxide on its surface. The part that is being treated forms the anode electrode of an electrical circuit. Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does.


Anodized aluminum parts are commonly found in aircraft and architectural components, as well as consumer goods such as appliances (refrigerators, microwaves, and barbecues), sporting goods (baseball bats, golf carts, and fishing equipment) and electronics (televisions, smartphones, and computers).

Anodizing is a relatively cost efficient process, as we have access to several anodizing lines, located in both Shanghai and the Jiangsu province. We usually anodize to neutral, grey, gold or black colors. This leads the surface to be considerably harder than un-anodized metals, which becomes more resistant to scratching and abrasions, provides insulation to the aluminum surface, which in turn protects from passage of electricity, and prohibits the use of metal as a conductor, helps elongate a natural resistance against the adverse effects of corrosion in aluminum, and dye becomes absorbed into the anodic film allowing all aluminum parts to be colored decoratively.

The broad-based benefits of anodizing include:

  • It’s a very thin coating compared to paints and powders.
  • Extremely durable, hard, abrasion resistant and long lasting.
  • The coating does not peel or chip.
  • Much harder surface than paint and powders.
  • Lasts indefinitely.
  • Environmentally friendly finish.
  • Can easily be recycled.
  • Inexpensive compared to painting and powder coating.


Bright Dip: This is a chemical treatment that is done previous to aluminum parts prior to anodizing. This ultimately enhances the sheen of the metal surface resulting in a polished and clean finish. A great benefit to bright dip is that when it is applied, there are no deposits left on the surface of the part.

Barrel and Bulk: A cost effective method for the andozising process and suitable for high volumes.Usually used in the screw and fastener industry, parts like nuts, bolts, and screws can be anodized in large quantities and in a wide variety of colors. While it has a decorative and high impact look, barrel and bulk also provide great protection against corrosion.
