What is the difference between anodic oxidation and conductive oxidation of aluminum alloy?

Nov 27, 2022

The difference between anodic oxidation and chemical conductive oxidation:

1. Different production processes:

1, anodic oxidation is the process of forming a layer of oxide film on aluminum products (anode) under the action of external current.

2, chemical conductive oxidation (also known as chemical oxidation) does not need electricity, only need to soak in the solution, is a pure chemical reaction.

2. Production time:

1. Anodizing takes a long time, and the production process takes dozens of minutes.

2, the production process of chemical conductive oxidation requires a very short time, generally in a few seconds can be completed.

Three, wear resistance:

1, the anodized film has several microns to dozens of microns, has good hardness and wear resistance, can be used in the production of kitchenware and other daily necessities.

2, chemical conductive oxidation film thickness is thin, about 0.3 ~ 0.5μm, poor wear resistance.

Four, different electrical conductivity:

1. The film produced by anodic oxidation has good insulation performance.

2, aluminum parts after chemical conductive oxidation has a certain corrosion resistance and conductivity, in electronic equipment, aluminum parts after chemical conductive oxidation can prevent electromagnetic signal interference.

V. Different scope of application:

1, anodic oxidation of casting aluminum anodic oxidation effect is not good, not suitable for complex aluminum products.

2, chemical conductive oxidation can be used for deformation of aluminum electrical parts, applied to not suitable for anodic oxidation of large parts or components.
