Zinc-Cobalt alloy plating
The appearance is similar to hexavalent chromium plating, and it provides good plating coverage even on complex shapes. It is ideal for cost reduction from hexavalent chromium plating for small parts!
It has been used as an alternative plating to chrome plating. Since it has good adhesion for plating, it can be barrel plated even for parts with shapes like blind holes. When compared to trivalent chrome barrel plating: - Corrosion resistance (with the same substrate specifications): Trivalent chrome plating > Tin-cobalt alloy plating - Plating adhesion: Trivalent chrome plating < Tin-cobalt alloy plating - Which is more expensive: Trivalent chrome plating > Tin-cobalt alloy plating Hexavalent chrome plating has excellent film hardness and corrosion resistance, but it can only be plated using fixtures. In contrast, tin-cobalt alloy plating and trivalent chrome plating can be barrel plated, which leads to higher productivity and easier cost reduction. Each has its own characteristics, so I believe it is important to choose based on the intended use and other factors. If you could provide details about the intended use and requirements, I would be happy to suggest the most suitable surface treatment.
