Nacobre Denomination: 1100
Designation: Electrolytic Tough Pitch (ETP)

The most appreciated property of this copper is the high electrical and thermal conductivity as well as the mechanical resistance and corrosion resistance. The conductivity is measured as of 1913 under agreement of the International Annealed Copper Standards (IACS) as a percentage of the average conductivity of the high purity copper to which it was assigned a value of 100% IACS. Due to the improvement of the refination copper methods it is currently possible to get conductivity values up 102% IACS.
