Aluminium Chemical Polishing

Chemical polishing is an industrially-employed surface finishing technique used for aluminum alloys that yields high-quality results in terms of brightness, levelness, smoothness, and scale removal.
Typically, this process is utilized as a pre-treatment before plating, and is particularly effective in achieving a bright finish prior to anodizing.
