Manganin filse yon alyaj kwiv-manganèz-nikèl (CuMnNi alyaj) pou itilize nan tanperati chanm. Alyaj la karakterize pa fòs elektwomotif tèmik (emf) ki ba anpil konpare ak kòb kwiv mete.
Manganin filse tipikman itilize pou fabrikasyon estanda rezistans, rezistans fil presizyon blesi, potansyomètr, shunt ak lòt konpozan elektrik ak elektwonik.
