Chemical composition : Minimum requirement of Copper including Silver in 99.90%.

Physical properties :

Conductivity

- Minimum 100.0%

Resistivity varies between 0.01724   m/MS

As per International Annealed Copper Standard (IACA) At 20oC.

or SL mm2 / m

(Resistivity is iverse value of conductivity)

 

These are produced in Wire Bars, Cakes, Slabs, billets, ingots and ingots bars and shapes.

Wire bars are normally produced 54” (1.372 meters) in length.
