Alkaline zinc nickel alloy brightener BZ-617 is an alkaline zinc nickel alloy electroplating process designed to meet the market needs of up to 16% nickel alloy content.
This electroplated alloy can provide excellent corrosion-resistant appearance and tolerance to post-passivation heat treatment.
Can provide a complete range of coatings, including: color blunt, blue blunt, white blunt and black blunt.
Zn-327 produces a black decorative passivation layer with high corrosion resistance on the zinc-nickel alloy coating with a nickel content of 12-18% through a simple dipping process.
Suitable for rack plating and barrel plating, with high tolerance to zinc impurities.
Zn-325 is suitable for trivalent chromium silver-white passivation of zinc-nickel alloys, with good corrosion resistance
It is suitable for the passivation of alkaline or acid zinc-nickel layer, both rack plating and barrel plating. The resulting bright passivation layer is high temperature resistant and can support one hour at 120℃.
Zn-324 is a colorful trivalent chromium passivation film for electroplating zinc-nickel alloy workpieces. This process can produce bright, light-colored (color between yellow and green) film, and has high corrosion resistance. For traditional multicolored hexavalent chromium film passivation, this treatment provides users with a safer choice. It can be applied to hanging and rolling process applications.
Zn-323 can produce a blue passivation layer with excellent corrosion resistance on zinc-nickel alloy coatings with a nickel content of 12-15%. Through a simple dipping process, a uniform blue passivation layer can be produced with good bonding force. The sealing treatment can further improve the corrosion resistance and make the appearance of the coating change into the color of silver-stainless steel.
zinc-nickel alloy trivalent chromium black passivation agent produces a black decorative passivation layer with high corrosion resistance on the zinc-nickel alloy coating with a nickel content of 12-18% through a simple dipping process .
