Tlhahiso: Tsoalo ea Manganin (1892)
Tšimoloho ea6J12e simoloha morao ho qapuoeng ha Manganin ke rasaense oa Leborithane Edward Weston ka 1892.
l 1887: Weston o ile a theha Constantan, motsoako oa pele oa ho hanyetsa oa TCR o tlase.
l 1892: Manganin e ile ea hlahisoa ka mokhoa oa Cu86%, Mn12%, Ni2%.
l Katleho ea mantlha: TCR e haufi le lefela haufi le mocheso oa kamore, e netefatsang khanyetso e tsitsitseng.
l 1901–1990: Li-resistor tsa Manganin li sebelitse e le tekanyetso ea molao bakeng sa ohm United States.
Tlhahiso ena e thehile motheo oa thepa eohle ea sejoale-joale ea ho hanyetsa ka nepo.
Tsoelo-pele: Ho tloha ho Manganin ho isa ho 6J12
6J12 ke mofuta o ntlafalitsoeng le o tloaelehileng oa Manganin oa setso oa Chaena, o ntlafalitsoeng bakeng sa litlhoko tsa indasteri tsa sejoale-joale.
Lilemong tsa bo-1950: Chaena e qalile R&D e ikemetseng le ho etsa hore li-alloy tse nepahetseng li fumanehe sebakeng sa tsona ho felisa ho itšetleha ka thepa e tsoang kantle ho naha.
l 1994: Chaena e ntshitse GB/T 15018-1994, e reha semmuso motsoako o ntlafalitsoeng wa 6J12.
l Lintlafatso: Ho ekelitsoe trace Si le Fe ho ntlafatsa ho hanyetsa mocheso le ts'ebetso ea ts'ebetso.
Molemo: Botsitso bo betere dibakeng tse nang le mocheso o phahameng, mongobo o phahameng le dibakeng tse thata tsa indasteri.
