CNC Machining Materials: Metals and Plastics

CNC machining is known for exceptional precision and flexibility. While the technology is vital, selecting the right material is often even more important. Metals and plastics remain the two most widely used material categories due to their favorable mechanical and chemical properties.

Why Material Selection Matters

Material choice affects:

• Machinability


• Strength and durability


• Surface finish


• Chemical resistance


• Weight and heat performance


• Cost efficiency

CNC Machined Metals

1. Aluminum

Features: Excellent machinability, lightweight, corrosion-resistant.

2. Stainless Steel

Features: High strength, temperature resistance, corrosion resistant.

3. Carbon Steel

Features: Very strong, affordable, reliable mechanical properties.

4. Brass

Features: Easy to machine, conductive, attractive finishing.

5. Copper

Features: Outstanding electrical & thermal conductivity.

6. Titanium

Features: High strength, lightweight, biocompatible.

CNC Machined Plastics

1. ABS

Features: Tough, good for prototypes, easy to machine.

2. POM (Delrin/Acetal)

Features: Low friction, dimensionally stable.

3. Nylon

Features: High strength, flexible, wear-resistant.

4. Polycarbonate

Features: Very impact-resistant, transparent.

5. PEEK

Features: High-performance plastic, heat & chemical resistant.

6. PTFE (Teflon)

Features: Extremely low friction, chemical resistant.

Metal vs. Plastic: How to Choose?

Conclusion

Choosing the right CNC machining material is essential for achieving optimal performance. Metals provide high strength and durability, while plastics offer lightweight, versatile, and cost-effective solutions. Both categories play a crucial role across industries, and the ideal selection depends on the specific application needs.
