Black high-nickel zinc alloy plating
Achieves 2 to 3 times the corrosion resistance of trivalent black! Significantly improves the shortcomings of trivalent black, such as "poor color tone" and "weak against scratches"!
Commonly known as "High Nickel Black," this surface treatment is achieved by applying a chemical conversion treatment to an alloy plating of 15% nickel and 85% zinc, resulting in corrosion resistance that is 2 to 3 times greater than trivalent black. This surface treatment significantly improves the shortcomings of trivalent black, such as "poor color tone" and "vulnerability to scratches."
