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.
Yes. Aluminium machines very accurately and can hold tight tolerances, making it an excellent choice for components where precision and repeatability are essential.
Aluminium is widely used in aerospace, electronics, medical devices, automotive, and scientific equipment due to its combination of strength, light weight, and corrosion resistance.
Aluminium is lighter and generally easier and faster to machine than steel, which can lower production costs and reduce component weight.
However, steel may be preferred for parts requiring higher hardness or wear resistance.
Not always. Aluminium naturally forms a protective oxide layer. However, finishing processes like anodising can improve surface durability, appearance, and corrosion resistance for certain applications.
Selecting the appropriate material and grade is among the important early decisions you'll make when designing your CNC machined component. In this blog we look at the most common grades of aluminium, one of the most versatile metals, and the factors to consider to select the best grade for your next project.
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.
