FAQs

What are the most commonly used aluminum alloys, and why are they chosen?

The most popular grades are 6061 (versatile, easy to machine, corrosion-resistant, ideal for structural parts) and 7075 (high strength, commonly used in aerospace and high-load applications). Aluminum alloys are preferred for their lightweight nature, excellent strength-to-weight ratio, good machinability, and corrosion resistance—making them easier and less expensive to cut than steel.

What are the common challenges in aluminum CNC machining, and how can they be avoided?

Key challenges include built-up edge (material sticking to the tool), thermal deformation, poor surface finish, or workpiece distortion—mainly due to aluminum’s softness and high thermal conductivity. Solutions include using proper coolant, optimizing cutting parameters (higher speeds, lighter feeds), selecting coated tools, and controlling clamping forces to prevent deformation.

What are the common surface finishing options, and when should each be used?

Popular options include anodizing (improves corrosion resistance and hardness; can be colored; best for functional and decorative parts), bead blasting/polishing (enhances surface smoothness and appearance), and powder coating (provides durable, weather-resistant finish). Choose anodizing for functional protection, polishing for aesthetics, and powder coating for outdoor or high-wear applications.
