Alloy 290/C17200 waya alloy nickel-copper maka potentiometers/shunts

A na-amata MANGANIN nke ọma site na obere okpomọkụ dị n'etiti 20 na 50 °C yana ọdịdị parabolic nke usoro R (T), nkwụsi ike dị elu nke iguzogide eletriki ogologo oge, obere EMF okpomọkụ megide ọla kọpa na ezigbo njirimara ọrụ.
Agbanyeghị, enwere ike ibu ibu okpomọkụ dị elu n'ime ikuku na-anaghị eme ka oxidation dị. Mgbe ejiri ya maka resistors ziri ezi nwere ihe kachasị mkpa, a ga-eme ka resistors ahụ kwụsie ike nke ọma, okpomọkụ ntinye ekwesịghịkwa ịgafe 60°C. Ịgafe okpomọkụ kachasị elu na ikuku nwere ike ibute nguzogide nke usoro oxidizing na-emepụta. Ya mere, nkwụsi ike ogologo oge nwere ike imetụta adịghị mma. N'ihi ya, nguzogide yana oke okpomọkụ nke nguzogide eletriki nwere ike ịgbanwe ntakịrị. A na-ejikwa ya dị ka ihe nnọchi dị ọnụ ala maka ihe mgbakwunye ọlaọcha maka itinye ígwè siri ike.
