FAQ
What Are the Common 6063 Aluminum Grades for CNC Machining?
6063 aluminum is commonly used in several tempers, including 6063-T5, 6063-T6, 6063-T52, and 6063-O. Each temper offers different strength, formability, and machining performance, so the right choice depends on part function, tolerance, and surface treatment needs.
6063-T5: Offers good dimensional stability and excellent anodizing performance. Commonly used for CNC machined profiles, frames, brackets, heat sink bodies, and guide rails.
6063-T6: Provides higher strength and hardness than T5. Suitable for support frames, mounting plates, equipment housings, connector parts, and structural components.
6063-T52: Balances moderate strength, formability, and surface quality. Often used for aluminum tubes, sleeves, extruded profiles, covers, and light-duty frames.
6063-O: Softer and easier to form, but lower in strength. Suitable for thin-wall parts, formed profiles, decorative covers, and components requiring bending or shaping.
What Are the Common Machining Risks of 6063 Aluminum?
Common risks of 6063 aluminum machining include thin-wall deformation, burrs, dimensional variation, tool built-up edge, clamping marks, surface scratches, and uneven anodizing results.
These issues can affect assembly accuracy, appearance, and part reliability. Proper fixture design, sharp tools, suitable cutting parameters, surface protection, and quality inspection help reduce these risks.
