Chemical Brightening
Etching
Etching produces a matt finish which will cover most extrusion lines, surface scratches and give an even coverage. If etching does not cover the extrusion lines polishing would be required to blend in the surface prior to etching.
Semi-Bright
This creates a matt finish to the aluminium but with a brighter appearance when compared to just etching.
Chemical Brightening
This delivers a bright decorative finish to the work and is often used to create a high degree of reflectivity to the surface.
As a result of their chemical make-up not all aluminium alloys are suitable for chemical brightening. If you require any advice on this subject, feel free to contact us.
The picture below show the difference in appearance when different types of aluminium alloys are used.
