Our Aluminum CNC Machining Capabilities

As a professional aluminum CNC machining manufacturer, we integrate CNC milling, CNC turning, drilling, tapping and composite machining to meet diverse custom part requirements. Whether you need one-off prototype samples or large-scale batch production, we maintain consistent dimensional accuracy and excellent surface quality for every aluminum component. Our team strictly follows international manufacturing standards, conducting full-process quality inspection to eliminate defective products and ensure every part matches your engineering drawings and application requirements.

Premium Aluminum Alloy Materials We Process

We work with a wide range of high-quality aluminum alloys with different mechanical properties to fit various industrial scenarios. 6061 aluminum features excellent machinability, good toughness and outstanding corrosion resistance, ideal for general mechanical parts and structural components. 7075 aluminum boasts ultra-high strength and hardness, widely used for high-load aerospace and automotive precision parts. 5052 aluminum offers great ductility and anti-rust performance, perfect for thin-shell parts and electronic equipment accessories. We can also process other customized aluminum grades according to your special project demands.

Complete Post-Processing & Surface Finishes

To maximize the performance and aesthetics of aluminum CNC parts, we offer comprehensive post-processing services. Our available finishes include hard anodizing, decorative colored anodizing, mirror polishing, matte sandblasting, chemical passivation, deburring and laser marking. These treatments effectively improve the aluminum parts’ durability, scratch resistance and oxidation resistance, while meeting strict appearance standards for commercial and industrial products. All finishing processes are customizable based on your usage environment and design specifications.
