Making my own Zinc Anodes?
Hello Caswell Forums,
I'm in the process of buying some CopyCad Zinc solution and brightener as I'm hoping to put together my own set-up (3 gallon). I'll be doing mostly fasteners during a automobile restoration. I have a basic power supply, and since I work on a Galvanizing line, I hope to make my own Zinc anodes (have access to 190tons of molten Zinc!). I can also get many different types of acids as well as yellow chromate solution. The nice part is that I would be able to make anodes of any size if needed.
My question is, the zinc I have access to is not absolutely pure.
It contains .125% Al and .030% Fe.
Will the percent of Aluminum and Iron present in the zinc have any real negative effect on plating that you'd know of? Does the Zinc need to be 100% pure?
Cheers, Mark.
