Cyanide Copper Alternative
We want to plate electroless nickel directly onto zincated aluminum.
We want to plate electroless nickel directly onto zincated aluminum. Can this be done or must we first plate with a cyanide copper strike? D. D.
Yes, you can plate directly on zincated aluminum with electroless nickel. To improve adhesion, the parts should undergo a low-temperature bake after the plating is completed.
If you decide, instead, to use a copper strike, you should be aware that a number of vendors have non-cyanide alkaline copper strike baths that work very well.
