Comment choisir le bon métal alliant vitesse d’usinage et durabilité ?

How Do I Select the Right Metal for Both Machining Speed and Durability?

Key Selection Criteria: Balancing Speed and Strength

Selecting the right metal for CNC machining involves balancing machinability (how quickly and cleanly a metal can be cut) and durability (its strength, hardness, and corrosion resistance). The ideal material depends on your part’s performance requirements, cost targets, and operating environment.

Top Metal Choices for Machining Speed and Durability

1. Aluminum 6061

   • Excellent machinability and corrosion resistance

   • Tensile strength: ~310 MPa

   • Widely used in aerospace, automotive, and robotics

   • Aluminum 6061 machining supports high feed rates with minimal tool wear

2. Brass C360

   • Highest machinability rating (100%)

   • Excellent dimensional stability and corrosion resistance

   • Ideal for precision valves, connectors, automation components, and fittings

   • Brass CNC machining delivers fast machining with tight tolerances

3. Stainless Steel SUS303

   • Moderate machinability with high wear and corrosion resistance

   • Tensile strength: 500–700 MPa

   • Common in medical devices, food processing equipment, and marine hardware

   • SUS303 machining offers better cuttability than SUS304 while maintaining strong durability

4. Titanium Ti-6Al-4V

   • Exceptional strength-to-weight ratio and top-tier corrosion resistance

   • Tensile strength: ~900 MPa

   • More difficult to machine, but required for aerospace, medical, and oil and gas components

   • Titanium CNC machining uses slower cutting speeds but provides unmatched durability

Practical Material Selection Tips

• For high-volume production with moderate strength needs: choose Aluminum 6061 or Brass C360.

• For high-strength components in demanding environments: select Stainless Steel 303/304 or Titanium Ti-6Al-4V.

• Use surface treatments like anodizing, passivation, or electropolishing to enhance corrosion and wear resistance without changing the base material.
