Nickel Anodes

Nickel S-Pellets

Nickel S-Pellets™

Nickel S-Pellets™ are a high purity form of sulphur-activated nickel widely used for electroplating with titanium anode baskets. S-Pellets™ are produced by a unique carbonyl gas refining process at the Clydach Nickel Refinery in the UK.

The controlled and consistent purity of S-Pellets™ and the advantages associated with its distinctive shape and sulphur activation make this product attractive for high-end plating (e.g. high-speed engineering, electronics, electroforming) with titanium anode baskets:

  • Carbonyl refining produces the purest form of nickel available
  • Sulfur activation promotes uniform dissolution and low operating voltage, even in chloride-free plating baths
  • Unique shape prevents the formation of bridges and voids in the basket
  • Settles uniformly in basket, ensuring uniform current density and high quality deposits
  • Flows easily into regular and shaped baskets of various mesh sizes
  • Safe to handle (no sharp edges)
  • Dissolves at 100% anode efficiency in common nickel plating solutions – with or without chlorides
  • Dissolution produces minimal metallic residues
  • Proven and trusted by the world's leading electroplaters

Electrolytic Nickel S-Rounds™

Electrolytic Nickel S-Rounds™ are a high purity form of sulfur-activated nickel specifically designed for electroplating with titanium anode baskets – especially in chloride-free plating baths.

The sulphur in this product does not enter the plating solution; it forms an insoluble nickel sulphide residue, which is 100% contained using cloth anode bags, where it acts to remove unwanted copper impurities.

The controlled and consistent quality of S-Rounds™, their distinctive shape and size, and the advantages of sulfur activation make S-Rounds™ ideally suited for high-end electroplating applications (e.g. high-speed engineering, electronics, electroforming):

  • High purity
  • Sulfur activation promotes uniform dissolution and low operating voltage, even in chloride-free plating baths
  • Unique shape prevents the formation of bridges and voids in the basket
  • Unique shape ensures good solution flow and mixing through the basket
  • Settles uniformly in basket, ensuring uniform current density and high quality deposits
  • Flows easily into regular and shaped baskets of various mesh sizes
  • Safe to handle (no sharp edges)
  • Dissolves at 100% anode efficiency in common nickel plating solutions – with or without chlorides
  • Produces minimal metallic residues upon dissolution
  • Proven and trusted by the world's leading electroplaters

Depolarized® Nickel Anode Bar

For large-scale plating without anode baskets, we have DEPOLARIZED® ("decarburized") wrought nickel anodes. They are made by melting nickel and adding elements which improve anode dissolution and reduce metallic residue. When dissolved, DEPOLARIZED® nickel anodes form a light green nickel oxide film mixed with metallic particles. They are used with high pH nickel baths (above pH 4) and will remain active where other anodes become wholly or intermittently passive. Compositions are listed in the table.

Produced in a range of shapes and lengths, they can be used as principal or auxiliary anodes. Wrought DEPOLARIZED® nickel anodes dissolve with exceptional uniformity and at relatively low dissolution potentials.
