High hardness and corrosion resistance, with heat resistance and dielectric strength functions, also adopted in semiconductor applications!
We would like to introduce a case where "components for humidification applications in fuel cell vehicles" were processed using sulfuric acid hard anodizing. This processing features higher hardness and corrosion resistance compared to sulfuric acid hard anodizing, as well as excellent wear resistance and fewer cracks in the anodized coating. The material used is AC4CH, with an anodized thickness of approximately 10μm, aimed at improving corrosion resistance. Please feel free to contact us if you have any inquiries. 【Case Overview】 ■ Material: AC4CH ■ Anodized Thickness: Approximately 10μm ■ Purpose: Improvement of corrosion resistance *For more details, please download the PDF or feel free to contact us.
