1. Kupu Whakataki
Ko nga koranu FeCrAl e whakamahia ana i roto i te whānuitanga o nga tono pāmahana teitei.
Ko Constantan [Cu55Ni45] he iti te whakarea pāmahana o te parenga me te mea he koranu parahi, he ngawari te hoko. Ko etahi atu koranu-atete tonu ko te manganin [Cu86Mn12Ni2], te Cupron [Cu53Ni44Mn3] me te Evanohm.
Ko te whanau Evanohm o te nickel-chrome alloys [Ni72Cr20Mn4Al3Si1], [Ni73Cr20Cu2Al2Mn1Si], he nui te parenga, te iti o te pāmahana o te aukati, te iti o te hikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohiko (Galvani potential) ki te whakamahana maimoatanga.
