Why Choose Aluminum for CNC Machining?

Aluminum is arguably the most popular material in the CNC machining industry. It offers engineers a “sweet spot” of physical properties, making it an incredibly versatile, cost-effective, and aesthetically pleasing metal for almost any modern application.

Whether you need the versatile and highly weldable Aluminum 6061 or the aerospace-grade, ultra-high-strength Aluminum 7075, this material delivers:

Incredible Strength-to-Weight Ratio: About one-third the weight of steel, yet strong enough for demanding structural applications.
Exceptional Machinability: Allows for rapid material removal rates, keeping machining times short and manufacturing costs low.
Outstanding Surface Finishing: Takes exceptionally well to various surface treatments, including clear/color anodizing, bead blasting, and powder coating for enhanced durability and aesthetics.
Excellent Thermal & Electrical Conductivity: Perfect for heat sinks and electronic enclosures.

As your manufacturing partner, XML utilizes advanced multi-axis CNC technology to cut complex aluminum geometries with flawless precision.
