-----Zinc Alloy differences and plating
February 21, 2011
I'm producing a lighter and I need it to have an excellent plating that looks good and is resistant to scratches (from keys, coins, etc)
Currently we are using this zinc alloy to cast our parts:
Zinc 97-98%
Aluminum 2-3%
Magnesium 0.01%
Lead 0.005%
Potassium 0.003%
Copper 0.001%
My manufacturer is proposing to use:
Zinc 90-94%
Aluminum 3.5-4.5%
Copper 0.75-1.25%
Lead 0.005%
Potassium 0.003%
Magnesium 0.03-0.08%
Will this second alloy allow for a better plating?
What would be the plating type that will yield a better finish on this alloy ?

The increased copper will be detrimental to the plate-ability and corrosion resistance of the subsequent plating.
