Ọla kọpa nickel Alloy bụ nke ọla kọpa na nickel na-emekarị. Enwere ike ịgbaze ọla kọpa na nickel ọnụ n'agbanyeghị pasent ole. Dị ka ọ na-adịkarị, resistivity nke CuNi alloy ga-adị elu ma ọ bụrụ na ọdịnaya Nickel buru ibu karịa ọdịnaya ọla kọpa. Site na CuNi6 ruo CuNi44, ihe mgbochi sitere na 0.1μΩm ruo 0.49μΩm. Nke ahụ ga-enyere ndị resistor aka imepụta ịhọrọ waya alloy kacha dabara adaba.
