Notes on properties and use

   
  • chemical element (the third most abundant of all elements on earth)
  • the most abundant metallic element on earth (7.57% by mass)
  • thermal conductivity 235 W/(m*K)
 

* International Annealed Copper Standard = IACS
The relative electrical conductivity of copper has been set as being 100% IACS, with the following values derived from this for other metals:
silver = 106%, gold = 72%, iron = 17%
