Chem-Film FAQs

How does chem-film treatment differ from other surface treatment methods?

Compared to other methods like anodizing and electroplating, chem-film treatment focuses more on forming a thin yet effective conversion coating to provide corrosion resistance and superior surface protection.
What is chem-film treatment?

Chem-film treatment involves a chemical reaction between chemicals and the surface of aluminum alloys to form a conversion coating, enhancing the corrosion resistance and other properties of aluminum alloys.
Does aluminum alloy retain its conductivity after chem-film treatment?

Yes, chem-film treatment typically retains the conductivity of aluminum alloy while improving corrosion resistance.
How long does the corrosion resistance effect of chem-film treatment last?

The durability of corrosion resistance depends on the specific application environment and the application of the components. In some cases, chem-film treatment can provide long-term corrosion protection.
What is the main application of chem-film?

Chem-film is mainly used in aerospace, automotive, electronics, and other fields to improve the corrosion resistance of aluminum alloys, enhance conductivity, and provide aesthetic improvements.
