How to Compare Alodine and Anodizing Creatingway
Alodine coating is one of aluminum finishing, meaning the aluminum or aluminum alloy adopt chrome phosphorus technology, the parts need to dip in phosphorizing liquid, make chemical reaction on surface, thus forming one protection film, now, most of aviation aluminum alloy parts have used this alodine finishing, its main function make aluminum alloy materials isolation, have preservation effect, improve primer adhesion effect, keep parts conductivity. So alodine coating main function make parts surface have conductivity function.
Aluminum Alodine Finishing and Anodizing Finishing Information
Alodine liquid has below different types to make aluminum finishing
- alodine 600, the parts surface will be yellow after process.
- alodine 1200,1200S,, the parts surface will be gold yellow (deep yellow) after process.
- alodine 1000,1000L,10001, the parts surface will be nature after process.
- main has gold yellow and nature.
Anodizing coat has common and hard anodizing (Type II or III)
Firstly, their coating thickness is different. the anodizing finishing meanings aluminum or aluminum alloy parts under corresponding electrolytic solution and specific technology condition, due to with the addition of voltaic, will form a layer oxidation film on aluminum parts surface, then make our parts appearance is perfect.
The benefit of anodizing finishing
- Protective properties
- Enhance the binding force between organic coverage and part surface.
- Enhance the binding force between inorganic covering layer and part surface
The advantage of anodizing finishing to our parts
- Anodizing multi-colors. Like nature, black, red, blue, purple.
- After sanding, anodizing, it can cover a little bit machining line on surface to make parts appearance perfect, and protect part surface.
- The anodizing layer thickness is 2-5μm, so it will not affect part assemble function.
- The hard anodizing is similar process, but the anodizing thickness is thicker than common anodizing, it is more than 12.5-100μm.the surface protection will be better.
Currently, more and more our customers have asked us to do aluminum alodine finishing for aluminum parts, so I will suggest you to know more on them different above. Meanwhile, Creatingway also provide the others finishing service to you, more information, visit our parts finishing services.
