Ni90Cr10 bụ austenitic nickel-chromium alloy (NiCr alloy) maka ojiji na okpomọkụ ruo 1200°C (2190°F). A na-eji alloy mara elu resistivity, ezigbo oxidation resistance na ezigbo nkwụsi ike ụdị. Ọ nwere ezi ductility mgbe ojiji na magburu onwe weldability.
A na-eji Ni90Cr10 mee ihe maka ọkụ ọkụ eletrik na ngwa ụlọ na ọkụ ọkụ ụlọ ọrụ. Ngwa ndị a na-ahụkarị bụ ígwè dị larịị, igwe na-agba agba, igwe na-ekpo ọkụ mmiri, ihe na-akpụzi rọba, igwe na-ere ere, ihe tubular nwere sheashed metal na ihe katrij.
N'ihi njiri mara mma nke ukwuu nke oxide elu, Ni90C10 na-enye ndụ ọrụ dị elu ma e jiri ya tụnyere nickel-chromium alloys asọmpi.
