Machining 6061 aluminum is often the starting point for engineers who need lightweight, corrosion-resistant, and cost-effective CNC parts. The alloy offers a practical balance of strength, machinability, availability, weldability, and anodizing response. It is widely used for optical mounts, motion-stage housings, robotic frames, medical-equipment housings, fixtures, brackets, and structural components. However, choosing 6061 does not…
