WET-CHEMICAL ETCHING OF METALS

Copper, silver and vanadium are strongly etched by this etching mixture. Aluminium, titanium, tung-sten and nickel experience only a weak etching. The noble metals gold, platinum and palladium are not etched. Experience has shown that with copper in (electrical) contact with chromium, a greatly reduced etching rate of chromium can occur.
