"Plating Aluminium Wheel"
I try to gold plate aluminium wheel. Is there somebody can advise me the best plating thickness and specification of plating sort. I plan to plate it with:
3. Acid dip
4. Double zincate
5. Copper cyanide strike (low free cyanide)
6. Copper cyanide bright plate
7. Bright Acid Copper
8. Bright Nickel plate
9. Brush gold plate
I already plate successful on small piece of cutting Aluminium Wheel, but I don't know what the best thickness spec plating of Copper & Nickel.
Or do you have other sort of treatment that more efficient or stronger, please help me.
Thank you very much,

Hi Anton. Suggest you get a copy of the MFSA's "Quality Metal Finishing Guide to Nickel-Chrome Coatings" from www.nasf.org. It's only a few dollars and explains all the relationships between thicknesses and corrosion resistance. You might consider electroless nickel in place of the copper cyanide strike, and I think you definitely need duplex nickel (semi-bright followed by bright). Good luck.
