What it is and what it does. White bronze (copper-tin) brightener is the additive system for white bronze plating, the nickel-free white finish that is used to replace bright nickel on skin-contact hardware.
- Pale blue to green-tinted clear liquid, dosed into the copper-tin electrolyte.
- White bronze gives a white deposit without nickel, which makes it the standard option for hardware that must meet nickel-release rules.
- The copper to tin ratio in the deposit sets the colour, and the additive system controls the balance and the brightness.
