Alpha Case Etch is an aqueous 2% hydrofluoric acid (HF) solution. It is an etchant for titanium, but it also works on aluminum alloys. This product is usually used in conjunction with Kroll's Reagent to reveal the alpha case layer of a titanium alloy. The sample is usually etched with Kroll's Reagent first, then this solution. The alpha case structure, if present, will appear near the surface as a layer of white grains. 

This product is made with ACS reagent grade hydrofluoric acid. The formula is listed in ASTM standard E 407 as number 11.
