Brasses are copper and zinc alloys. The properties of electrolytic brass-plated coatings vary, depending on the content of the main alloying element, which is zinc. The chemical composition of the coating has also a determining influence on its colour, which varies from red (high copper content) to different shades of gold-yellow. The standard type of brass-plated coatings is yellow.
They are characterised by high aesthetic qualities and protect against corrosion. The anti-corrosion properties of brass-plated coatings allow for use in slightly damaging environments. Years-long analysis of the properties and applications of brass-plated coatings have shown their high rated use in products like ERICSSON nuts.
