配制方法：	Nickel-plating formulas are recommended for plating on aluminum, beryllium, thorium, uranium, and zinc. Their high pH makes them particularly desirable for plating on these active metals. Formula 2 is said to give a more ductile deposit and is not limited in thickness. The nickel deposits from these baths, however, are somewhat porous. If an impervious coat on beryllium is required, formula 2 as a strike, followed by plating in formula 4 is recommended. Formula 3 is recommended for plating on zirconium.
