Sreang manganinIs cóimhiotal copair-mangainigh-nicil (cóimhiotal cumnni) é le húsáid ag teocht an tseomra. Tá an cóimhiotal tréithrithe ag fórsa leictreamaighnéadach teirmeach an -íseal (EMF) i gcomparáid le copar.
Is iondúil go n -úsáidtear sreang manganin chun caighdeáin friotaíochta a mhonarú, friotóirí créachta sreinge beachtais, poitéinsiméadair, shunts agus comhpháirteanna leictreacha agus leictreonacha eile.
