Aluminum CNC Turning Parts

In today’s advanced manufacturing landscape, aluminum CNC turning parts have become essential components across virtually every industry due to their exceptional strength-to-weight ratio, corrosion resistance, and machining efficiency. At China Metal Castings, we leverage state-of-the-art CNC turning technology to produce precision aluminum components with tolerances as tight as ±0.005mm and surface finishes reaching 0.4μm Ra. Our expertise spans from prototyping to high-volume production, serving sectors including aerospace, automotive, electronics, and medical devices.

Why Aluminum Stands Out for CNC Turned Components

Material Advantages

✔ Lightweight (Density: 2.7 g/cm³ – 1/3 that of steel)
✔ Excellent machinability (Allows cutting speeds up to 3,000 SFM)
✔ Natural corrosion resistance (Forms protective oxide layer)
✔ Superior thermal conductivity (120-240 W/m·K)
✔ Electrical conductivity (35-50% IACS)
✔ Cost-effective production (Reduced machining time vs. steel)
