Aluminum etching 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.
Aluminium chemical etching process
The process involves etching aluminum parts to assess the grain size, prepare the surface for subsequent FPI (pre-pen etch) and detect surface defects.

Blue Etch Anodize (BEA) Inspection
Blue Etch Anodize is a nondestructive test that can reveal minimal surface defects in titanium materials. Titanium is commonly used in critical rotating components for both aerospace and power generation industries.
Anodic Etching Inspection
Anodic etch is only applicable to stainless steel and nickel-based materials. This nickel alloy inspection method is used to detect surface defects, grain structure, grain size and more.
Non-Destructive Testing (NDT)
Find out about the range of NDT services Element uses to evaluate the properties of a material, parts, products, welds, or systems without materially affecting the integrity of the items being tested.
Element's mechanical tests show whether a material or part is suitable for its intended mechanical applications.
