Sandelin Effect
The highest zinc coating is reached when the silicon in the steel is 0,04 to 0,12%, this range is called the ‘Sandelin Curve’.

From this graph, it can easily be seen that the addition of nickel to the zinc bath decreases the coating thickness significantly when the silicon equivalent of steel is in Sandelin range.

Why Nickel?

• Advantages of Nickel when working with reactive steels;
  • Prevents high coating thicknesses.
  • Prevents growth of Fe-Zn alloy layer.
  • Prevents dark grey coatings.
  • Prevents peeling of coating.
  • Increases the coating homogenity.
• Zinc saving from 5% to 15% in weight.
• Increases coating ductility.
• Smoother and brighter surface finish.
• Increases the fluidity of the Zn bath.
• Aesthetical coating appearance.

Why Nickel Tablet?

• Up to %30 reduction in nickel usage compared to Zinc-Nickel alloy ingots and powder Nickel applications.
  • Zinc Nikel Alloy Ingot, 1.7 kg Ni addition per ton zinc.
  • Nickel Powder 1.8 kg Ni addition per ton zinc.
  • Nickel Tablet, 1.2 kg Ni addition per ton zinc.
• The implementation is very simple and fast.
• No special expertise or tools required.
• Nickel floats on the surface of the zinc bath more than other methods, therefore does not settle down to zinc ash and dross.
• Nickel automatically dissolves in zinc bath.
• No dependency on purchasing of HG / SHG Zinc.

Why ANI METAL SmartNi?

• Others: Nickel + Wax
• ANI Metal SmartNi: Nickel + Wax + X (X is our “know-how”).
  • ANI Metal SmartNi provides a heat shield during burn-off, thus preventing consumption due to oxidation.
  • Increases the solubility in zinc.
  • Prevents precipitation, therefore helps reduce dross formation
