Aluminum CNC Machining

Aluminum is a light-weight alloy with excellent strength-to-weight ratio, high thermal and electric conductivity, low density and natural deterioration resistance. It has superb machinability, welding and electroplating residential or commercial properties as well as great corrosion resistance.

Lightweight aluminum is a material that is easy to cut and machine, and aluminum alloys can be quickly, properly grated, pierced, and machined using CNC machining. After machining, lightweight aluminum has a low threat of contortion or issues and is very easy to polish and color.

Aluminum is among the most common materials used in the aerospace, medical, auto and motorcycle industries.

Cost-saving Design Tips

1.Design for manufacturing

The first tip to save cost when machining an aluminum alloy part is to follow design-for-manufacturing principles to limit difficult-to-machine features, such as setup numbers, inspection dimensions, tight tolerances, and deep pockets with small radii. 

2.Choose the right alloy

Using the most innovative and pricey alloy might not be needed if the part is just a prototype. 6061 T6 aluminum is a good choice.


Aluminum CNC machining is the process of using computer-controlled machines, such as a CNC mill and a CNC lathe, to shape, cut, and finish aluminum parts.
