Description
Nickel(II) Fluoride Tetrahydrate Product Overview
Nickel(II) fluoride tetrahydrate (NiF2·4H2O) is a light green crystalline powder with a nickel content of about 34–35.5%. It is sparingly soluble in water.
Its main application is cold sealing of anodized aluminum: nickel fluoride baths close the pores of the anodic oxide layer at room temperature, improving corrosion resistance with lower energy use than hot water or steam sealing. It also serves as a catalyst component, in fluorination chemistry and as a raw material for other nickel and fluoride compounds.
Nickel compounds count as carcinogenic and sensitizing in the EU, so nickel fluoride is available only for professional use. Related compounds in our range also include Nickel Sulfate, Nickel(II) chloride 6-hydrate and Zirconium fluoride.
Key Applications of Nickel(II) Fluoride Tetrahydrate
Typical uses include, for example:
🔩 Anodizing
Cold sealing of anodized aluminum.
⚗️ Catalysts
Nickel as well as fluoride source for catalysts.
🧪 Fluorine Chemistry
Raw material for fluoride compounds.
🏭 Nickel Compounds
Starting material for other nickel salts.

⚠️ Safety & Handling: May cause cancer by inhalation, allergic skin and respiratory reactions, and is harmful if swallowed or inhaled; contact with acids releases hydrogen fluoride. For professional use only. Use local exhaust ventilation and wear gloves, eye protection and respiratory protection. Store locked, in tightly closed containers away from acids. Always consult the Safety Data Sheet (SDS), because it contains the full classification and handling instructions.
Frequently Asked Questions
How does nickel fluoride cold sealing work?
Nickel and fluoride ions react in the pores of the anodic aluminum oxide at room temperature, partially closing them as well as improving corrosion resistance.
Who can purchase nickel fluoride?
It is available only for professional industrial use because nickel compounds count as carcinogenic.
How can I get a price and documents?
Prices depend on quantity, packaging and destination, so please contact us with your required volume. We then send a quotation together with the CoA and SDS.
