Cable and wire shielding that once was made of bronze alloy or copper now is often stainless steel or alloy steel clad on both sides with copper. The copper assists in reducing crosstalk and electrically protects the cable from lightning strikes or ground faults, while the steel strength increases resistance to gnawing rodents and reduces cost by allowing thinner gauge material to be used. And newly developed material systems offer improved attenuation performance over copper based alloys at lower cost.
