Metallographic etchants are chemicals that reveal microstructural details on a mirror-polished metal specimen. These etchants selectively etch or stain microstructural features, such as grain boundaries or metal phases, allowing for detailed study under a microscope. The products listed in this category, also known as micro etchants, are specifically designed for microscopic studies. They are milder and different from macro etchants, which are intended for visual inspections.

The selection of the optimum etchant is crucial in sample preparation. We offer all the popular metallographic etchants listed in the ASTM Standard, suitable for etching iron, carbon steel, stainless steel, superalloy, titanium, aluminum, copper, bronze, brass, and others. If you need assistance in selecting the right product for your project, please feel free to give us a call.
