Abstract: The present invention is directed to a nickel-based alloy, such as INCOLOY or INCONEL, clad stainless steel sheath tubing material for heating elements. This clad material is designed to minimize the cost of heating elements generally constructed entirely of nickel-based alloys alone while providing necessary material requirements of weldability, hot strength, corrosion resistance, thermal shock resistance, and formability.

Abstract: An asymmetric composite cable shield for use in communications cable that includes a protective layer clad with inner and outer layers of copper or a copper alloy, in which the inner layer is thicker than the outer layer.
