Cuprothal 294 / CuNi40 Tembaga Nikel Alloy Resistance Wire

Katrangan singkat:

Constantan Wire karo resistivity Moderate lan koefisien suhu kurang resistance karo resistance warata / kurva suhu liwat sawetara luwih akeh tinimbang "manganin". Constantan uga nuduhake ketahanan korosi sing luwih apik tinimbang man ganins. Panggunaan cenderung diwatesi ing sirkuit ac.

Kawat Constantan uga minangka unsur negatif saka termokopel tipe J kanthi wesi minangka positif; termokopel tipe J digunakake ing aplikasi perawatan panas. Uga, iku unsur negatif saka jinis T thermocouple karo OFHC Tembaga positif; termokopel tipe T digunakake ing suhu kriogenik.

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 gandhengane karo logam liyane.

Seri paduan nikel tembaga: Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi44.
