Nickel anode (used for electrolytic coatings) is made of two types: non-passivable - NPAN brands and regular - NPA-1 and NPA-2 brands.

NPAN anodes dissolve evenly during electrolysis, without the formation of sludge, and are preferred.
Nickel anodes NPA 1 (Semi-finished anode nickel) are used for nickel plating.
The production of nickel anodes NPA 1 occurs by the hot rolling method (hot rolled), nickel grade N1 is used and cleaner (copper no more than 0.06%). Anodes are produced in the form of nickel strips of rectangular and oval sections.

The dimensions of oval anodes and the maximum deviations for them must correspond to those given in the following table:

Major and minor axes of the oval	Limit deviations along the length of the major and minor axes of the section	Anode length	Limit deviations along the length
80×35	-2.5	100	10
		400
		500
		600
80×35	±2.5	700	±10
		800
		900
		1000
		1200
		1500

The thickness and width of rectangular anodes and the maximum deviations for them must correspond to the given in the following table:

Thickness	Limit deviations in thickness	Width	Maximum deviation in width at width
			100-300	350-600
4	±0.50	100-600	±5	±10

Anodes with a rectangular cross-section are made with a width that is a multiple of 50 mm.

The surface of the anodes must be free of contaminants that make it difficult to inspect.
Films, bubbles, cavities, cracks, slag inclusions, etc. are not allowed on the surface of the anodes. delaminations, protrusions from overflowing calibers and other defects, if they are during control cleaning bring the anodes beyond the maximum deviations in thickness.
Anodes must be cut evenly. The miter cut should not take the anodes beyond the maximum dimensional deviations. On NPAN brand anodes, chips and cracks are allowed, which do not take the anodes beyond the maximum dimensional deviations.
