Cobalt Brush Plating Solution plates a very hard wearing layer that’s a lot harder than nickel and plates at three or four times the speed.
It can be used as a barrier layer, as it slows down the migration of copper into plated gold layers. An alternative barrier layer could be our white bronze or our Palladium Brush, Tank Solution, Nickel Brush or our Nickel Tank Solution.
Cobalt has a slight bluish lustre (although not as pronounced as chromium). Although it is a lot less hypoallergenic than nickel, we do not recommend it for jewellery purposes.

Our brush plating equipment is powered by our EasyPlater. It’s very straightforward to use, compact and lightweight.
