The Difference Between Anodizing and Conductive Oxidation
Nov 20, 2018

We are manufacturer specialined in CNC machining,lathing,turning,sheet metal fabrication...etc,with material like aluminum alloy,stainless steel,brass,steel,galvanized sheet plate and so on.

We usually requested to do surface treatment on aluminum alloy as anodizing or conductive oxidation.

Then let's talk about the difference between anodizing and conductive oxidation,which is very common in hardware parts machining. 

1) Anodizing is carried out under high voltage, it is an electrochemical reaction process; and conductive oxidation (also called chemical oxidation) does not require electricity, only need to be soaked in the syrup, it is a Kind of purification reaction.

2) Anodizing takes a long time, often taking several tens of minutes, while conductive oxidation requires only a few tens of seconds.

3) The film formed by anodization has a few micrometers to several tens of micrometers, and is hard and wear-resistant; the film formed by conductive oxidation is only 0.01-0.15 micrometers, and the wear resistance is not very good, but it is both conductive and atmospheric corrosion resistant. It is its advantage.

4) The oxide film is inherently non-conductive, but because the film formed by conductive oxidation is really thin, it is electrically conductive.

We have rich experience in making cnc machining parts with anodizing surface treatment,and our surface treatment quality is quite stable so far.

Hopefully to establish a business cooperation relationship with you via our professional skills.

With the experience and responsibility,we will improve ourselves continously and be your reliable supplier!
