Spa Plating’s Dull Nickel Tank Plating Solution has many useful engineering applications.

It can be used to build up worn or over-machined parts and because very thick coatings of over 2,000 microns (0.2mm) are possible, it is ideal for electroforms or building up nickel on mandrels.

The deposit is semi-matt but it can be polished easily on a buffing machine to a mirror finish.

We recommend this solution is continuously filtered through an inline filter (beaker plating) or a filter pump for larger installations.

Note: You can use the Nickel Tank Plating Calculator for help with pH adjustments of this solution. Please click on the ‘Calculator’ tab to reach this.

HS Code: 3824 99 70.

500ml beaker plating set up for dull nickel plating driven by the Microplater (white box on the bottom left) and continuously filtered through an inline cartridge filter pumped by a peristaltic pump.

Nickel continuously pumped using a peristaltic pump connected to
an online filter.

Machining a thick layer of dull nickel.

Features Benefits
Can be plated very thick. Ideal for building up worn or over-machined parts (see second video under Videos tab).
No brightener additions necessary. Easy to maintain. Just check the pH periodically.
Stress-free dull deposit easily polished. Dual function deposits decorative and corrosion resistant.
Plating with chromium results in a surface with a low coefficient of friction. Very useful for sliding parts.


Nickel Tank Plating Calculator

Amp and Time Settings

pH Control

How to use the Nickel Tank Calculator :

1. In the first box, enter the thickness that you want to plate to in microns.

2. In the second box, enter the surface area of the article in square centimetres (cm2).

3. Click the ‘Calculate’ button.

4. Read off the amp setting for your rectifier, the plating time and the amount of Nickel Tank Maintenance Brightener to add before starting the plating sequence.

5. The weight of nickel plated is shown in the final box.

How to use the pH Control Calculator :

1. Measure the pH of the Nickel Tank Plating Solution and enter the result in the box marked ‘Actual pH’.

2. Enter the pH that you wish to attain in the box marked ‘Desired pH’.

3. Finally enter the volume of the plating tank/beaker.

4. Click the ‘Calculate’ button.

5. Read off the weight of Nickel pH Adjuster to add to attain the desired pH.

  1. If a high plating factor is used, agitation will need to be increased.
  2. Higher temperatures facilitate higher plating rates (by allowing for
    higher plating factors) and lower stress deposits.
  3. Appearance of the plate at lower thickness is dull or matt turning more
    of a satin shade at thicknesses over 25 microns.
  4. The pH usually increases with usage and can be reduced using Nickel pH
    The amount of pH adjuser can be calculated using the Nickel Tank Plating Calculator.
  5. Higher current densities (plating factor) generally results in a higher rate of increase of pH.
