Pri Stock 1mm * 10mm 0Cr25Al5 Flat Riban Round Burr Bright Sifas Strip
1. Entwodiksyon
FeCrAl alyaj yo itilize nan yon pakèt aplikasyon pou wo-tanperati.
Constantan [Cu55Ni45] gen yon koyefisyan tanperati ki ba nan rezistans ak kòm yon alyaj kòb kwiv mete, se fasil soude.Lòt alyaj rezistans konstan gen ladan manganin [Cu86Mn12Ni2], Cupron [Cu53Ni44Mn3] ak Evanohm.
Fanmi Evanohm nan alyaj nikèl-chrome [Ni72Cr20Mn4Al3Si1], [Ni73Cr20Cu2Al2Mn1Si], gen gwo rezistans, koyefisyan rezistans tanperati ki ba, fòs elektwomotif ki ba (Galvani potansyèl) lè yo an kontak ak kòb kwiv mete, segondè fòs rupture, epi tou yo trè estab. nan tretman chalè.
