Metal Strippers
Stripping plated metal deposits is often a necessity due to unforeseen issues in the process. Rather than scrapping the parts and paying for them, stripping and re-plating is the best option, if possible. Some plated deposits are very difficult to remove, so it is important to share the following parameters when searching for the best chemistry to remove a metal coating:
- Type of metal coating to be stripped – Example – high phos electroless nickel, acid zinc-nickel, bright tin, etc.
- Approximate coating thickness – Example – 8 microns, 3 tenths, 1 mil, etc.
- Quantity of parts to be stripped

Description
If a metal can be plated, it can also be stripped. Often there are several different formulations to remove the same deposit, and some chemical stripping products will remove more than one type of plated metal. Here is a list of plated metals that can be stripped:
- Electroless Nickel – Low, Mid & High Phos as well as composite baths like Teflon and Boron Nitride
- Electrolytic Nickel – Bright, Semi-Bright, Sulfamate, Wood’s, Micro-Porous
- Tin – Bright, Matte, Tin-Lead, Bismuth-Tin
- Precious Metals – Gold, Silver, etc.
- Copper – Cyanide Copper, Acid Copper, Bronze Alloys
- Zinc – Alkaline, Acid Chloride
- Zinc-Nickel – Alkaline & Acid
- Alloys – Tin-Nickel, Black Nickel, Tin-Zinc
