Ihe mgbawa Cupronickel bụ ọla kọpa nwere nickel dị ka ihe bụ isi alloying. A na-akpọ eriri ọla kọpa-nickel nke dabeere na ọla kọpa-nickel alloys nwere ihe atọ dị ka zinc, manganese, aluminum, wdg. bụ nke a na-akpọ zinc-nickel-nickel strips, manganese-nickel-nickel strips, na aluminum-nickel-nickel strips ya mere. Ọla kọpa-nickel alloy nwere ezigbo nguzogide corrosion, ike ọkara, nnukwu plasticity, enwere ike ịhazi ya site na nrụgide ọkụ na oyi.
A na-ekewa ibe ọla kọpa na-acha ọcha ụzọ ise: ibe ọla kọpa na-acha ọcha nkịtị, ibe ọla kọpa na-acha ọcha ígwè, ibe ọla kọpa ọcha nke manganese, ibe ọla kọpa na-acha ọcha zinc na ibe ọla kọpa na-acha ọcha aluminom.
Mpekere ọla kọpa na-acha ọcha nkịtị na-enwekarị akara ngosi alloy anọ dịka B0.6, B5, B19, na B30. Ndị a na-ejikarị bụ B19 na B30, ma enwere akararị karịa na usoro ọkọlọtọ America. Mpempe ọla kọpa na-acha ọcha bụ ihe ngwọta siri ike na-aga n'ihu nke Cu na Ni kpụrụ, nke nwere eriri cubic na-adabere na ihu, dịka e gosiri na foto 1-18. Mgbe okpomọkụ dị ala karịa 322 degrees, ihe osise ọla kọpa-nickel nwere mpaghara okpomọkụ dị obosara nke nhazi nke metastable, na-agbakwunye ihe atọ dị ka Fe, Cr, Sn, Ti, Co, Si, Al na Cu-Ni alloy. Etc., nwere ike ịgbanwe mejupụtara, okpomọkụ nso na ọnọdụ nke metastable decomposition, na nwekwara ike melite ụfọdụ Njirimara nke alloy.
