The alloy imagwiritsidwa ntchito popanga miyezo yolimbana, chivundikiro cha waya chivundikiro, ma pontiometers, amasudzulana ndi magetsi ena
ndi zigawo zamagetsi. Altoy wamkuwa uyu wandickel ali ndi mphamvu yotsika kwambiri yamagetsi (Emf) vs mkuwa, yomwe
zimapangitsa kuti zikhale zabwino kuti mugwiritse ntchito mabwalo amagetsi, makamaka DC, komwe amachititsa kuti emf itheke
zida. Zigawozo zomwe alloy iyi imagwiritsidwa ntchito nthawi zambiri imagwira ntchito kutentha kwa firiji; Chifukwa chake kutentha kwake kutentha kwa kutentha
Kutsutsana kumayendetsedwa kwa magawo 15 mpaka 35ºC.

Manganin waya wa Mamangain ndi Anoy-Manganel-nickel-nickel (CUNNI ALTOY) kuti mugwiritse ntchito kutentha kwa firiji. The alloy imadziwika ndi mafuta ocheperako otsika (Emf) poyerekeza ndi mkuwa.
Ma waya a Mamangain amagwiritsidwa ntchito popanga miyezo yolimbana, mosagwirizana ndi waya wotsutsana, opanga ma pontions, amasudzulana ndi zigawo zina zamagetsi.
