Our White Bronze Brush Plating Solution plates an anti microbial layer of white bronze onto a range of different metals.
It can be used instead of nickel because it
- has a similar hardness
- has a similar colour
- can be used to plate a barrier layer between gold on to copper and its alloys
We recommend you use our platinum range of electrodes with our white bronze plating solution.
Please note: This white bronze plating solution solution is air-sensitive so when you’re not using it, keep the lid tightly shut and try to reduce the air space remaining in the bottle. You can do this by adding marbles or glass beads to the bottle or squeezing out the excess air at the top of the bottle. You can also store the solution in a special syringe that’s available on the online shop.
We recommend this solution is stored long-term between 2 – 5 °C
If you don’t follow these precautions then the tin component in the white bronze plating solution will degenerate.

- Increasing the voltage increases the plating rate. An increase of
from 3.0 volts to 3.5 volts more than doubles the plating rate.
- Increasing the voltage causes the copper to tin ratio to increase.
- If using copper electrodes, use a voltage range of 2.6 – 3.1 volts.
- Stress can be relieved by heating to 260 °C for 1 hour.
- Important note: When coming out of
long term storage, allow solution to reach room temperature before use.
- As the solution ages, the copper content of the plate increases.
- Just before plating, we recommend that the work piece be warmed
by placing it under a tap to approximately 30 °C.
- Thickness and consistency will vary over the item. Please refer to our
X-ray analysis illustrating these variations.
- Please note: This is an air-sensitive solution. When not in use,
keep the lid tightly shut and take measures to minimise the
air space remaining in the bottle. These can include adding marbles
or glass beads to the bottle or squeezing out the excess air at the
top of the bottle. You can also store the solution in a special syringe
that’s available on the online shop.
Failure to observe the above precautions will result in the degeneration
of the tin component in the solution.

to minimise air contamination.
