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."

Company information
We are plating small products such as screws and precision parts (compatible with φ0.6 mm) using a barrel. We offer various types of plating including zinc plating (trivalent white, black, red, blue, yellow, green, purple, pink / hexavalent colored chromate, hexavalent black chromate), nickel plating (glossy, matte, double nickel, copper under nickel, black nickel, stainless steel compatible), high nickel zinc alloy plating (stainless steel compatible), lead-free electroless nickel plating, tin plating, black dyeing (iron, brass, stainless steel compatible), passivation treatment, and non-chrome Kirins treatment, among others, with various combinations available. We will flexibly process according to the shape, material, surface condition, and quantity of each product. (We can process from a single screw.) Please entrust us with items that frequently cause issues with automatic plating equipment. We will finish them beautifully without any problems.
