Alloy 290/ C17200 nickel-ọla kọpa alloy waya maka potentiometers / shunts

A na-amata nkenke na-eguzogide alloy MANGAN nke ọma site na ọnụọgụ okpomọkụ dị ala n'etiti 20 na 50 Celsius C nwere ọdịdị parabolic nke akụkụ R (T), nkwụsi ike ogologo oge nke nkwụsi ike eletrik, EMF dị ala dị ala karịa ọla kọpa na ezigbo arụ ọrụ.
Otú ọ dị, ibu ọkụ dị elu na ikuku na-adịghị oxidizing ga-ekwe omume. Mgbe a na-eji ya maka ndị na-eguzogide nkenke nke nwere ihe kachasị elu, a ga-eji nlezianya mee ka ndị na-emegide ya guzosie ike na okpomọkụ ngwa ngwa ekwesịghị gafere 60 ° C. Ịgafe oke okpomọkụ na-arụ ọrụ na ikuku nwere ike ime ka nkwụsị nkwụsị na-emepụta site na usoro oxidizing. N'ihi ya, ogologo oge nkwụsi ike nwere ike imetụta na-adịghị mma. N'ihi ya, resistivity yana ọnụọgụ ọkụ nke ọkụ eletrik nwere ike gbanwee ntakịrị. A na-ejikwa ya dị ka ihe ngbanwe dị ọnụ ala maka ihe nrịba ọlaọcha maka mgbanye ígwè siri ike.
