An electromagnetic shielding material includes multiple strands of an electrically conductive yarn that are arranged as a braided, knitted, or woven mesh. Each strand of the electrically conductive yarn comprises one or more electrically conductive filaments; each electrically conductive filament comprises a core of a first electrically conductive material surrounded by a sheath of a second electrically conductive material different from the first electrically conductive material. The first electrically conductive material exceeds the second electrically conductive material with respect to electrical conductivity, while the second electrically conductive material exceeds the first electrically conductive material with respect to one or more of tensile strength, corrosion resistance, or one or more other mechanical or chemical properties or characteristics. In many examples, the first electrically conductive material includes copper and the second electrically conductive material includes stainless steel.
