Compared to the conventional black nickel, the Black Nickel produced by our company has a deeper color tone and very exceled in resistance to discoloration. Often used in optical components for antireflection reasons.
素材 鉄、ステン、銅、真鍮、ADC、ZDC、 AL ( A1000~A7000 )
下地処理 電解ニッケル or 無電解ニッケル
・Solidity(Hv): Hv500~700 (It becomes 900Hv or more to a heat treatment)
It plates solely with a chemical reaction and without the process of electrolyzing. Therefore, it allows to plate areas with complicated shapes where electroplating Moreover, the solidity is higher than an electric nickel, allowing it to excel in resistance.
