Prìs stoc 1mm * 10mm 0Cr25Al5 Flat Ribbon Round Burr Bright Surface Strip
1. Ro-ràdh
Alloidhean FeCrAl air an cleachdadh ann an raon farsaing de thagraidhean àrd-teòthachd.
Tha co-èifeachd resistivity teòthachd ìosal aig Constantan [Cu55Ni45] agus mar alloy copair, tha e furasta a shàrachadh. Am measg aloidhean seasmhach eile tha manganin [Cu86Mn12Ni2], Cupron [Cu53Ni44Mn3] agus Evanohm.
Tha an teaghlach Evanohm de aloidhean nicil-chrome [Ni72Cr20Mn4Al3Si1], [Ni73Cr20Cu2Al2Mn1Si], àrd an aghaidh, co-èifeachd teòthachd ìosal, feachd electromotive ìosal (comas Galvani) nuair a bhios iad a’ conaltradh ri copar, neart tensile àrd, agus cuideachd gu math seasmhach a thaobh airson làimhseachadh teas.
