1. Utangulizi
Aloi za fecral zinazotumiwa katika anuwai ya matumizi ya joto la juu.
Constantan [Cu55Ni45] ina mgawo wa chini wa joto na kama aloi ya shaba, inauzwa kwa urahisi. Aloi zingine za kupinga kila wakati ni pamoja na Manganin [Cu86mn12ni2], Cupron [Cu53Ni44mn3] na Evanohm.
Familia ya Evanohm ya aloi ya nickel-chrome [NI72CR20Mn4Al3si1], [NI73CR20CU2Al2mn1si], ina upinzani mkubwa, mgawo wa joto wa chini wa upinzani, nguvu ya chini ya umeme (Galvani uwezo) wakati unawasiliana na matibabu ya nguvu, na nguvu nyingi na nguvu nyingi.
