Keller’s Reagent (AKA Keller's etch) is the most popular metallographic etchant for etching aluminum alloys, except for high silicon content aluminum. It outlines all the common constituents, and with certain aluminum alloys will reveal grain size.

This product is made with ACS reagent grade chemicals. The formula is listed in ASTM Standard E 407 as number 3 "Keller’s".

For macro etching or aluminum weld inspection, try our Caustic etching solution (contains no HF).


User Instruction:

Use by immersion only to form a surface film. This may take several minutes. Wash in a stream of warm water afterward.
