What Makes Aluminum Ideal for CNC Machining?

Aluminum is the third-most abundant element in Earth’s crust, comprising roughly 8% of its weight. As a lightweight, non-ferrous metal extracted from bauxite ore, it became commercially viable after the development of the Hall–Héroult process in 1886. Today, it remains the most widely machined non-ferrous metal in the world.

At DEK, we machine all major aluminum alloy families — from the high-strength 2xxx and 7xxx aerospace series to the versatile 5xxx and 6xxx general-purpose alloys. Our CNC milling machines, CNC lathes, and precision grinding equipment handle everything from simple aluminum cutting to multi-axis complex geometries. Combined with our certified quality processes and in-house anodizing capabilities, we deliver production-ready aluminum parts that meet the strictest industry standards.
