Is there nickel plating at 99.86%

There is no value in specifying 99.86% electroplated nickel. The thickness is not a problem.

The problem with the purity specification is that impurities are measured in 0.001% or even lower, and the effects of some impurities at those levels can be devastating to the properties of the deposit.

Hello Shania.

Try Contacting the International Nickel Company (Inco).

Inco produces high purity nickel anodes that exceed your requirements. Inco has plating expertise to help you.

Thanks Peter, but Shania might be better off fleshing out her question than drawing more parties into the confusion  🙂

The problem isn't that our readers aren't knowledgable enough (some are from Inco and Falconbridge, and others have many decades of nickel plating experience). The problem is that her abstract phrasing has lead to our inability to figure out exactly what she is really after. We can easily guess that 99.86% has something to do with 3 sigma, but we can't relate why that number should be tied to the plating purity. Thanks.
