Aluminum Etch and Cleaning

Aluminum etch solution can be used for both cleaning and inspection where an alkaline bath made of sodium hydroxide (NaOH) is typically used for cleaning or etching aluminum parts. The process involves etching aluminum parts to assess the grain size, prepare the surface for subsequent FPI (pre-pen etch) and detect surface defects.
