Manganin wayaZomwe zimagwiritsidwa ntchito kwambiri pazida zotsika kwambiri zokhala ndi zofunikira kwambiri, zotsutsa ziyenera kukhazikika bwino ndipo kutentha kwa ntchito sikuyenera kupitirira +60 ° C.Kupitilira kutentha kwakukulu kogwira ntchito mumpweya kungayambitse kusuntha kosunthika kopangidwa ndi oxidizing.Choncho, kukhazikika kwa nthawi yaitali kungakhudzidwe molakwika.Chotsatira chake, resistivity komanso kutentha kwa kutentha kwa magetsi kungasinthe pang'ono.Amagwiritsidwanso ntchito ngati zotsika mtengo m'malo zinthu zogulitsira siliva pakupanga zitsulo zolimba.

Mapulogalamu a Manganin:

1;Amagwiritsidwa ntchito popanga mabala osalimba kwambiri

2;Mabokosi otsutsa

3;Zotchingira zida zoyezera zamagetsi

Manganin zojambulazo ndi waya amagwiritsidwa ntchito popanga resistors, makamaka ammeter shunts, chifukwa cha pafupifupi ziro coefficient kutentha kwa mtengo kukana ndi kukhazikika kwa nthawi yaitali.Otsutsa angapo a Manganin adakhala ngati muyezo walamulo wa ohm ku United States kuyambira 1901 mpaka 1990.Manganin wayaimagwiritsidwanso ntchito ngati chowongolera magetsi m'machitidwe a cryogenic, kuchepetsa kutentha kwapakati pakati pa mfundo zomwe zimafunikira kulumikizidwa kwamagetsi.

Manganin amagwiritsidwanso ntchito poyesa mafunde amphamvu kwambiri (monga omwe amapangidwa kuchokera kuphulika kwa zophulika) chifukwa ali ndi mphamvu yocheperako koma imakhudzidwa kwambiri ndi hydrostatic pressure sensitivity.
