CuNi2alloy panas resistance kurang digunakake digunakake ing mbobol sirkuit voltase kurang, relay kakehan termal, lan produk electrical kurang voltase liyane. Iki minangka salah sawijining bahan utama produk listrik voltase rendah. Bahan sing diprodhuksi dening perusahaan kita nduweni karakteristik konsistensi resistensi sing apik lan stabilitas sing unggul. Kita bisa nyedhiyakake kabeh jinis kawat bunder, bahan warata lan lembaran.
Paduan kasebut non-magnetik. Digunakake kanggo resistor variabel regenerator listrik lan resistor galur,
potensiometer, kabel pemanas, kabel pemanas lan tikar. Pita digunakake kanggo pemanasan bimetal. Bidang aplikasi liyane yaiku manufaktur termokopel amarga ngembangake gaya elektromotif dhuwur (EMF) sing ana hubungane karo logam liyane.
Seri paduan nikel tembaga: Konstantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi44.
