Aluminum CNC Machining Service

Overview

Why Choose Us for Aluminum Parts?

Aluminum is the most popular CNC material — excellent strength-to-weight ratio, corrosion resistance, thermal and electrical conductivity, and easy machinability. We specialize in 6061-T6 (general purpose), 7075-T6 (high strength aerospace), 2024-T3 (aircraft skin), and 5052 (sheet/enclosures).

All aluminum parts can be anodized Type II (decorative) or Type III (hard coat, wear resistant) in clear, black, red, blue, gold, and other colors. Tolerance ±0.005 mm, MOQ 1 piece.

FAQ

Aluminum CNC Machining Service — Frequently Asked Questions

6061-T6 is a general-purpose alloy with good strength, weldability, and corrosion resistance. 7075-T6 is a high-strength aerospace-grade alloy with ~50% higher tensile strength, but is more expensive and harder to weld.

Yes — Type III hard coat anodizing available in black, clear, and other colors. Standard thickness 25–50 μm, hardness 60+ HRC.

0.5 mm for 6061-T6. We recommend ≥0.8 mm for 7075 to avoid chatter and ensure good surface finish.

Yes — we routinely machine custom heat sinks with fin heights up to 50 mm and fin spacing down to 2 mm.
