Nickel Chloride, E.P. Grade for Electroplating
Also known as: Nickel(II) Chloride Hexahydrate, NiCl₂·6H₂O
Overview
Nickel Chloride, Product Overview
Nickel Chloride (NiCl₂·6H₂O) is the chloride source in nickel electroplating. In a Watts bath it works alongside Nickel Sulphate and Boric Acid: chloride ions keep nickel anodes dissolving evenly and raise bath conductivity. It is also the main component of the Wood's nickel strike, used to activate stainless steel and other passive surfaces before nickel plating. Shriji Chemicals® supplies E.P. (electroplating) grade Nickel Chloride from Dahanu Road, Maharashtra, with pan-India delivery.
Running a Nickel Sulphamate bath? Chloride is usually kept low in sulphamate electroforming, because excess chloride raises internal stress. Where a small chloride addition is used to help anodes dissolve, add it in measured amounts and monitor stress. Learn more about Nickel Sulphamate Solution.
Applications
Where Nickel Chloride is Used
Watts Nickel Bath
Chloride source alongside Nickel Sulphate, promoting even anode dissolution and higher conductivity.
Wood's Nickel Strike
High-chloride, acidic strike that activates stainless steel and other passive metals before plating.
Bright Nickel Plating
Part of bright and semi-bright nickel bath formulations for decorative and functional finishes.
All-Chloride Nickel Baths
Main nickel source in specialised all-chloride baths that run at high conductivity.
Quick Facts
FAQ
Common Questions about Nickel Chloride
What is Nickel Chloride used for in electroplating?
Nickel Chloride supplies chloride ions that keep nickel anodes dissolving evenly and raise bath conductivity. It is a standard ingredient of the Watts nickel bath and the main component of the Wood's nickel strike used to activate stainless steel before plating.
What is the difference between Nickel Chloride and Nickel Sulphate?
Both supply nickel ions. Nickel Sulphate is the main nickel source in a Watts bath, while Nickel Chloride is added mainly for its chloride, which promotes anode dissolution and improves conductivity. Higher chloride raises deposit stress, so the two are used in balance.
Can I add Nickel Chloride to a Nickel Sulphamate bath?
Only in small, controlled amounts. Excess chloride raises internal stress in sulphamate electroforming. Many low-stress operations keep chloride to a minimum and use Nickel Carbonate for nickel replenishment instead. Contact us for guidance on your bath.
