Chemical etching is a micro-machining manufacturing process to produce micron-size components by applying of a chemical etching solution to remove unwanted part in the work-piece material. In this study aluminium was etched by different chemical agents (acid and base solution). The effects of selected chemical etching agents on depth of etch as well as the etch rate was investigated for aluminium.
