C101 Machined Parts

A Guide to copper C101 CNC Milled & Turned Parts: Properties, Applications and Design Considerations

What is C101?

C101, also commonly known as CW004A is 99.9% pure copper. After silver, it is the next best conductor of electricity and therefore widely used in electronics applications. It is also used in a wide range of engineering applications due to high impact strength and ductility as well as corrosion resistance.

Main Attributes of C101:

  • Good to excellent corrosion resistance
  • Excellent electrical conductivity
  • Very good thermal conductivity
  • High ductility
  • High impact strength
  • Recyclable and sustainable
  • Poor weldability but otherwise easily joinable
  • Aesthetically pleasing
  • Distinctive smell and disagreeable taste
  • Yellowish/red metal
  • Subject to surface oxidation/patination
  • Non magnetic
  • Soft malleable metal
