Metallographic etchants are chemicals that can reveal microstructural details that would otherwise not be evident on a mirror-polished metal sample. The etchant will selectively etch or stain microstructural features, such as grain boundary or metal phases. These features can then be studied with a microscope. The products list in this category are also known as micro etchants and are designed for microscopic studies. They are milder than the macro etchants which are for visual inspections.
The selection of optimum etchant is very important in sample preparation. We carry all the popular metallographic etchants listed in the ASTM Standard for etching iron, carbon steel, stainless steel, superalloy, titanium, aluminum, copper, bronze, brass, and others. If you need help to select the right product for your project, please feel free to give us a call.
