What is aluminium?

Aluminium is a lightweight, non-ferrous metal valued in CNC machining for its excellent machinability, corrosion resistance, and strength-to-weight ratio. Available in various alloys, it is suitable for components ranging from intricate housings to structural frames across engineering, aerospace, and electronics sectors.

Why engineers choose aluminium for CNC machining

  • Outstanding machinability: Aluminium is softer than steel and chips cleanly, which allows fast cycle times, reduced tool wear, and tight tolerances. This makes it ideal for both prototypes and high-volume runs.
  • Excellent strength-to-weight performance: Many alloys such as 6061 and 7075 provide high specific strength, enabling lightweight parts without sacrificing mechanical performance.
  • Natural corrosion resistance: Aluminium forms a self-healing oxide layer that protects surfaces, often removing the need for coatings, though anodising can further improve durability and appearance.

Specifying aluminium machining for medical applications

Aluminium is not like stainless steel: there is no one 'stand out' grade that is the first choice for medical devices. There is no '316L' of aluminium. Instead, as a purchaser of medical component machining solutions, you are confronted with a plethora of aluminium grades – any, all or none of which may suit your specific medical application. To suggest that's a challenge is an understatement. But it also offers you a great opportunity to improve quality, consistency and savings. How so? Simply this… you won't be on '316L autopilot' as sometimes occurs in the world of stainless steel medical components.
