Process	Zinc & Nickel-plating Zinc-plating is used to improve corrosion resistance of steel components. There are 4 different methods of carrying out the process: using high cyanogen, low cyanogen, basic or low acid electrolytes. Ni-plating is used for decoration and corrosion protection of steel, Cu, Al and Mg; for leveling and smoothing out surfaces; for black coatings; for renowing worn machines components. Most Ni-plating is applied prior to Cr-plating. Two different electrolytes are used. The first, Watt's solution, is based on Ni-sulphate, Ni-chloride and boric acid. The second, Ni-sulphamate, is based on a salt-Ni-sulphamate.

Price notes	The first price on the cell refers to zinc-plating, the second one to nickel-plating. Over 5000 parts the price doesn't vary so much. The price is calculated for typical average thichnesses: 10 micron (Zn); 30 micron (Ni).
Environmental notes	High cyanogen and low cyanogen electrolytes are poisonous.
Additional info	Labour is the most important factor for pricing.
