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 in the Si killed steel, the example is 0,26% silicon, the coating thickness increases directly proportional with time, whereas in the unkilled steel, this increase is very slow. And even after 2 minutes dipping, the coating thickness is double in Si killed steel.

Sandelin Effect

Why Nickel?

  • Reactive Steels;
    • Prevents high coating thicknesses.
    • Prevents growth of Fe-Zn alloy layer.
    • Prevents dark grey coatings.
    • Prevents peeling of coating.
    • Increase the coating homogenity.
  • Zinc saving from 5% to 15% in weight.
  • Increase coating ductility.
  • Smoother and brighter surface finish.
  • Increase the fluidity of the Zn bath.
  • Aesthetical coating appearance.

Coating with Nickel

Why Nickel Tablet?

  • Less Nickel using up to 30% compared to Zinc-Nickel alloy ingot 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, 0.75 – 1 kg Ni addition per ton Zinc.
  • Removes workmanship from the nickel joint.
  • 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 tot zinc ash and dross.
  • Nickel automatically dissolves in zinc bath.
  • No dependency on purchasing of HG / SHG Zinc.

Why ANI METAL Nickel Tablet?

  • Others: Nickel + Wax
  • ANI Metal: Nickel + Wax + X (X is our “know-how”).
    • ANI Metal tablets create more heat shield when burn off therefore they prevent consumption by oxidation.
    • Increase the solubility in zinc.
    • Prevents the precipitation to dross.
