Rega Saham 1mm * 10mm 0Cr25Al5 Pita Datar Putaran Burr Strip Permukaan Cerah
1. Pambuka
Wesi FeCrAl digunakake ing macem-macem aplikasi suhu dhuwur.
Constantan [Cu55Ni45] nduweni koefisien suhu sing kurang saka resistivity lan minangka paduan tembaga, gampang disolder. Paduan tahan konstan liyane kalebu manganin [Cu86Mn12Ni2], Cupron [Cu53Ni44Mn3] lan Evanohm.
Kulawarga Evanohm saka wesi nikel-chrome [Ni72Cr20Mn4Al3Si1], [Ni73Cr20Cu2Al2Mn1Si], duwe resistance dhuwur, koefisien suhu kurang saka resistance, gaya elektromotif kurang (potensial Galvani) nalika kontak karo tembaga, kekuatan tensile dhuwur, lan uga banget stabil karo regards. kanggo perawatan panas.
