Over 2000 hours without red rust occurrence! Introduction of high nickel plating with high corrosion resistance surface treatment.
The "Zinc-Nickel Alloy Plating (High Nickel Type)" has excellent corrosion resistance and heat resistance among zinc-based alloy platings. It enables the trivalent chromate treatment with a black appearance, which was difficult with low to medium nickel. In salt spray tests, it demonstrates corrosion resistance exceeding 2000 hours of red rust. The heat resistance can withstand temperatures of 350°C without chromate. Additionally, since it is treated in an acidic bath, it can be plated on difficult materials such as high carbon steel and hardened steel. 【Features】 ■ Depending on the conditions, a nickel eutectic rate of 12-18% can be achieved ■ Capable of chromate colorization ■ Suitable for identification purposes of screws and similar items ■ Excellent corrosion resistance and heat resistance among zinc-based alloy platings ■ Capable of trivalent chromate treatment with a black appearance *For more details, please refer to the PDF document or feel free to contact us.
