Nickel plating is an electroplating process that adds a coating of nickel to the surface of the brass. The nickel plating provides a protective layer that can extend the life of the brass and keep it looking shiny and new for years. But sometimes, you may want to remove the nickel plating from your brass object. This can be done by using a chemical solution such as citric acid or by sandblasting. Let’s take a look at how you can strip nickel plating from brass.
Citric Acid Solution Method
The most common method of removing nickel plating from brass is to use a citric acid solution. Citric acid is a weak organic acid found naturally in citrus fruits, and it can be used to dissolve metal coatings like nickel plating. The process is fairly simple; just combine equal parts water and citric acid in a container, then submerge the brass object in the mixture. Let the object sit for 30 minutes, then remove it and rinse off any residue with warm water.
Sandblasting Method
Another way to remove nickel plating from brass is by sandblasting. Sandblasting uses compressed air to force abrasive materials against the surface of an object, which erodes away layers of material until only the desired result remains. For this method, you will need an industrial-grade sandblaster and fine-grained blasting media (e.g., aluminum oxide). Simply set up your sandblaster according to manufacturer instructions, fill it with blasting media, and direct it onto the surface of your brass object until all traces of nickel are gone. Make sure you wear safety goggles when sandblasting!
Conclusion:
Nickel plating is useful for protecting brass objects from corrosion and wear and tear over time; however, if you ever need to remove that layer of protection, there are two main ways you can do so: using citric acid or sandblasting with fine-grained blasting media. Both methods will get rid of unwanted nickel plating quickly and easily – just make sure you follow safety precautions when sandblasting! With these tips in mind, removing nickel plating from brass should be a breeze!
