Electromagnetic Shield Effect Evaluation Test (I)
Although thinner than a copper sheet, Copper-Iron Alloy is superior in
electromagnetic shielding effect .
The Copper-Iron Alloy that is 57 times thinner than the copper sheet has
an equal electromagnetic shielding characteristic.

Impedance characteristic is as follows based upon IACS (International Annealed
|±0.02µΩ is obtained for standard annealed copper.
However, the electro-conductive can descend depending upon the component proportion of the iron.
