    Material Selection Guide for CNC Machining

    Selecting the right material is crucial for the success of any CNC machining project. This guide helps you understand common material properties.


    Metals


    Aluminum Alloys

  1. 6061: Versatile with good machinability, suitable for most applications
  2. 7075: High strength, ideal for aerospace and defense applications
  3. 2024: High fatigue strength, suitable for structural components

    4. Stainless Steel

  4. 304: General purpose with good corrosion resistance
  5. 316: Enhanced corrosion resistance for marine and chemical environments
  6. 17-4PH: Precipitation hardened with high strength

    7. Titanium Alloys

  7. Lightweight and high strength
  8. Excellent corrosion resistance
  9. More difficult to machine with higher costs

    10. Engineering Plastics


    POM (Delrin)

    Self-lubricating properties, ideal for gears and bearings


    PEEK

    Heat and chemical resistant, suitable for aerospace and medical applications


    Nylon (PA)

    Good toughness and wear resistance at lower cost
