Wire manganinadia varahina-manganese-nikela firaka (CuMnNi firaka) ampiasaina amin'ny mari-pana. Ny firaka dia miavaka amin'ny hery electromotive mafana (emf) ambany dia ambany raha oharina amin'ny varahina.
Wire manganinadia matetika ampiasaina amin'ny fanamboarana ny fenitra fanoherana, tariby mazava tsara resistors ratra, potentiometers, shunts sy ny elektrika sy elektronika singa hafa.
