Micro Etchants

This section lists the recommended chemical solutions for the etching of specimens for metallographic examination. The solutions are used, with grinding and polishing techniques, to etch metals and alloys for microscopic examination; they provide detailed information on the structure and chemical composition of a specimen and are applicable to a wider range of metals and alloys when compared to the Macro Etch section.
This section is catalogued according to the etchants use (see left) and then tagged against each metal or alloy.
