Plating on difficult materials such as high carbon steel and hardened steel is possible using barrel plating technology in an acidic bath! *Supports from small-scale prototypes to mass production.
"High Nickel" has excellent corrosion resistance and heat resistance among zinc-based alloy coatings, and it enables the black appearance trivalent chromate treatment, which was difficult with low nickel. Since it is treated in an acidic bath using barrel plating technology, it can be plated on difficult materials such as high carbon steel and hardened steel. It mainly targets small items such as small screws, bolts, and nuts. Various coatings and paints can be applied after high nickel plating. 【Features】 ■ Excellent corrosion resistance and heat resistance ■ No red rust formation for over 2000 hours in salt spray test ■ Achievable nickel co-deposition rate of 12-18% ■ Heat resistance temperature of 350°C without chromate *For more details, please refer to the PDF document or feel free to contact us.
