Conductive material related to density

This chart illustrates the conductivity of metallic materials divised by the density. It clearly indicates the best conductive materials by weight unit. (siemens/(g/cm3))

  • In this case, Aluminium is confirmed as being one of the best material, but one has to consider also other issues than density: as by example mecanical strength, behavior against corrosion, melting point, fatigue effect in flexible structures or conductive yarns, price issue etc..
  • In composite structures or hybrids tehchnical yarns, one has also to consider the relative density of the final material
  • By example, a stainless steel has a density of 7,9 g/cm3 , but our new TIBTECH PAM/stainless fiber composite (dry impregnation) has a density of less than 4
