CNC Aluminum
CNC-machined Aluminum Alloys are widely used across various industries due to their lightweight, high strength, corrosion resistance, and excellent machinability. These alloys offer superior mechanical properties while maintaining cost-effectiveness, making them an ideal choice for aerospace, automotive, electronics, and industrial applications.

Material Profile
Why Aluminum Is The CNC Baseline
This section gives the single material family enough depth without inventing unsupported mechanical data.
Light weight and high strength
Aluminum alloys have a density of about 2.7 g/cm3, much lighter than steel, while selected grades such as 7075 approach steel-like strength.
Excellent corrosion resistance
Alloys such as 5052, 5083 and 6061 are suitable for wet or marine-adjacent environments where corrosion resistance matters.
Good machinability
6061 and 5052 cut, drill and mill efficiently, supporting high-precision parts with shorter machining time and lower tooling pressure.

Available Finishes
Finishes That Make Sense For Aluminum
Keep finish cards functional and quote-oriented, with enough guidance for users to select the right callout.
Bead Blasting
Creates a uniform matte texture and is often paired with anodizing for presentation parts.
Electropolishing
Bright surface option when smoother appearance and clean reflectivity are desired.
Compare & Decide
When To Pick A Different CNC Family
A single family page still needs exits, but they should be practical substitutions rather than a full catalog.
CNC Steel Alloys
Choose when weight is less important than strength, rigidity and lower material cost.
CNC Titanium Alloys
Choose for high-performance, corrosion-resistant parts where aluminum is not strong enough.
CNC Copper Alloys
Choose when electrical or thermal conductivity is the primary requirement.
