Plating brass
After the brass is formed or drawn in this case it will be degreased. A quick rinse in a caustic bath, water to remove the bulk of the caustic. "Britedipped" in chromic acid rinsed again to remove the chromic acid. Bright nickel plating uses an electrolyte that is mostly nitric acid with other chemicals that enhance the finish. Tumbled in a plating barrel for the amount of time decided by engineering to achieve the desired thickness.
I did electro-plating for an electronic manufacturer for five years.
