IACS

International Annealed Copper Standard - a measure of electrical conductivity agreed in 1913 with “pure” Copper set as 100%. Advances in copper refining mean that now the pure Copper can attain 103% IACS. The minimum requirement for High Conductivity Copper now is 101% IACS.

Ingot Casting, Casting
