Noted for being ductile and having good electrical and thermal conductivity. It forms the basis of a number of alloys e.g. brass and bronze

  • C101 - High conductivity - used in the electrical/electronic component industries.
  • C106 - available in sheet & strip in coil and tube it has excellent welding properties. It also can be offered in highly polished finishes for architectural purposes.
Material properties:
Density kg/m3 8900
Modulus of elasticity E GPa 110 to 120
Modulus of elasticity G GPa 40 to 47
Poisson's ratio v 0.33 to 0.36
Melting point C 1083
Note: These properties should be used for indication only as material properties vary from sample to sample.


Heat until it glows dull red, then cool (either slowly or by plunging it in water), the copper becomes very soft and easy to bend and work.


Not the easiest material to turn. I find turning it fast with cutting oil and very sharp tools and it will be fine.

The problem with copper is it is malleable and so flows very easily. This means cutting tools need to be sharp to avoid smearing the copper onto the part being machined.
