Our aluminium etching process is highly repeatable and consistent, offering a cost-effective and versatile manufacturing alternative to stamping, laser cutting and waterjet cutting.

How We Etch Aluminium

Machining aluminium and its alloys has consistently presented challenges for both traditional processes and chemical etching. During etching, aluminium releases heat energy, leading to the formation of rough, granular edges. The material is also extremely reactive with certain chemical etchants, requiring meticulous control to ensure precise parts.

At Precision Micro, we have pioneered a robust, proprietary solution for etching aluminium and its alloys, producing cleaner edge profiles with enhanced accuracy and efficiency. Our chemical etching process also offers exceptional control and accuracy, ensuring optimal part performance.

Complex Geometries Without The Cost

We use low-cost digital tooling to provide a rapid, cost-effective aluminium etching service. Using digital tooling also enables us to etch intricate, complex geometries without cost penalty and tight tolerances with accuracy to ±0.020mm. Additionally, prototyping is accelerated, allowing for efficient design iterations and faster time-to-market, providing an ideal alternative to traditional machining methods such as stamping and laser cutting.

Aluminium Grades Suitable For Chemical Etching

Our aluminium etching extends from pure aluminium to a wide range of aluminium alloys, including 3003, 5052,  6061 and 7075. We also work with aluminium bronze and aluminium polyimide film which is suitable for flexible electronics applications.
