Metallographic etchants

The attack etchants are used to examine the structure of metallic materials.

Metallographic etchants

The purpose of the micrographic analysis is to highlight the materials’ structure (inclusions, grain joins, phases…) thanks to an optical microscope. These etchants react either with preferential chemical attacks, or by colouring certain components instead of others).
