Why Choose Aluminum for CNC Machining?
Aluminum remains one of the most popular materials for CNC machining due to its exceptional properties:
- Lightweight yet strong: With a strength-to-weight ratio superior to many metals
- Excellent machinability: Allows for high-speed machining and complex geometries
- Superior thermal conductivity: Ideal for heat dissipation applications
- Natural corrosion resistance: Especially in marine and outdoor environments
- Good electrical conductivity: Perfect for electronic components
- 100% recyclable: An environmentally friendly material choice
Our expertise in aluminum machining enables us to maximize these inherent benefits while overcoming challenges like aluminum’s tendency to stick to cutting tools and its relatively low melting point.
