Chrome plated brass

Material : BR
Brass is an oxidizable alloy made of copper (Cu) and zinc (Zn). Brass is a ductile, malleable material and has good resistance to corrosion. Compared to copper, it has higher values of hardness, resilience and fusibility
Treatment: CR
Galvanic chrome plating uses electroplating technology or the technique that allows covering a non-precious metal with a thin layer of a more precious or noble or passivable metal by exploiting electrolytic deposition.
In this case the brass base is previously polished and covered with trivalent chromium.
