I-alloy yokumelana okunembile i-MANGANIN iphawuleka kakhulu yi-coefficient yokushisa ephansi ephakathi kuka-20 no-50 °C ngesimo se-parabolic se-R(T) curve, ukuzinza okuphezulu kokumelana kukagesi isikhathi eside, i-EMF ephansi kakhulu yokushisa uma kuqhathaniswa nethusi kanye nezakhiwo ezinhle zokusebenza.
Kodwa-ke, imithwalo ephezulu yokushisa endaweni engenawo umoya ingenzeka. Uma isetshenziselwa ama-resistor anembile anezidingo eziphezulu kakhulu, ama-resistor kufanele azinziswe ngokucophelela futhi izinga lokushisa lokusetshenziswa akufanele lidlule ku-60°C. Ukudlula izinga lokushisa lokusebenza eliphezulu emoyeni kungabangela ukukhukhuleka kokumelana okukhiqizwa yizinqubo ze-oxidizing. Ngakho-ke, ukuzinza kwesikhathi eside kungathinteka kabi. Ngenxa yalokho, ukumelana kanye ne-coefficient yokushisa yokumelana kukagesi kungashintsha kancane. Iphinde isetshenziswe njengento yokufaka esikhundleni engabizi kakhulu ye-silver solder yokufaka insimbi eqinile.
