Sreang Manganinis cóimhiotal copair-mangainéise-nicil (CuMnNi cóimhiotal) le húsáid ag teocht an tseomra. Tá fórsa electromotive teirmeach an-íseal (emf) tréithrithe ag an gcóimhiotal i gcomparáid le copar.
Sreang Manganina úsáidtear go hiondúil chun caighdeáin friotaíochta a mhonarú, friotóirí créachta sreinge cruinneas, potentiometers, shunts agus comhpháirteanna leictreacha agus leictreonacha eile.
