What Materials Are Commonly Used for CNC Machining?

Q1: What metal materials are suitable for CNC machining?

Common CNC machining metals include:

• Aluminum (6061, 7075)
  
  

• Stainless steel (304, 316)
  
  

• Carbon steel
  
  

• Brass and copper
  
  

Q2: Can plastic materials be CNC machined?

Yes. CNC machining is suitable for many engineering plastics such as:

• POM (Delrin)
  
  

• Nylon
  
  

• ABS
  
  

• PTFE
  
  

Q3: How is material selection determined?

Material selection depends on:

• Mechanical strength requirements
  
  

• Corrosion resistance
  
  

• Operating environment
  
  

• Cost considerations
  
  

Q4: Can one project use multiple materials?

Yes. CNC machining supports multi-material projects, especially for assemblies or functional testing.
