This material is a conductor.

  • Resistivity (rho) = 1.68 x 10^-8 ohm.m; conductivity (sigma) = 5.95 x 10^7 S/m.
  • This material falls in the conductor range.
  • Metals and most alloys sit in this range. Electrons move freely through the lattice with very little energy loss.
  • Resistivity and conductivity are exact mathematical inverses: rho = 1 / sigma. Knowing one fully determines the other.

Next stepRemember that the values shown are for 20 C. Resistivity rises with temperature in metals (positive temperature coefficient) and falls with temperature in semiconductors and insulators (negative temperature coefficient).
