Acid Etching

Acid Etching is defined as the process of cutting a hard surface such as metal using a corrosive chemical (etchant), which is usually some form of acid in order to create a design onto the metal. At Advanced Chemical Etching Ltd our preferred etchant is Ferric Chloride (FeCl3), acids dissolve metals by chemical reaction. Acid etching can be traced back as far as 1531, where the French scholar Jehan le Begue wrote a recipe for acid-etching on iron, distilling ammonium chloride, ordinary alum and ferrous sulphate in a mixture of water and vinegar. The acid etching process allows both surface etched detail and cut through areas to be produced at the same time onto metal thicknesses up to 1.5mm. Alternatively surface etched raised areas are produced onto one side only, as an example for the manufacture of metal etched paper dies, as per the photo on this page. Or detail can be surface etched into the metal surface only for etched presentation plaques or etched signage.

Unfortunately we are not able to put designs onto finished metal components or shaped metal items. All of our acid etching is performed utilsing perfectly flat sheets of metal. Please also note we are only able to acid etch metal.
