Chrome Stripping [India] 

++

I would like to have some help on a cost effective system of stripping chrome - nickle - copper from our aluminium products.

The aluminium product is first coated with copper then nickle and finally chrome.

My intention is to strip the product to it aluminium base.

If you have to strip copper nickel and chrome on aluminum substrate.

1. First you have to strip chrome by using hydrochloric acid or reverse current in electroclenaer solution.

2. After stripping chrome, rinse the parts in water then transfer to nitric acid for stripping nickel and copper.

How can I remove old chrome plating from motorcycle parts? They are made of aluminum, about 30 years old. Thanks
