Precision Aluminum Etching Services for High-Performance Components

Aluminum Etching Overview

Xinhsen specializes in precision chemical etching of aluminum (1000-7000 series) and aluminum alloys, delivering burr-free, stress-free components with exceptional accuracy. Our proprietary etching process enables complex geometries in aluminum that are difficult or impossible to achieve with mechanical machining, making it ideal for lightweight, high-strength applications across industries.

Key Advantages
✔ Material Integrity Preservation - No heat-affected zones or mechanical stress
✔ Ultra-Thin Capability - Process aluminum foils as thin as 0.02mm
✔ Complex Geometries - Achieve intricate patterns with sharp edge definition
✔ Rapid Prototyping - Turnaround in as little as 3 working days
✔ Cost Efficiency - No hard tooling required, ideal for design iterations
