1. Kev Taw Qhia

FeCrAl alloys siv rau ntau yam kev siv kub siab.

Constantan [Cu55Ni45] muaj qhov kub thiab txias coefficient ntawm resistivity thiab ua ib qho tooj liab alloy, yooj yim soldered. Lwm cov alloys tsis tu ncua-tiv taus suav nrog manganin [Cu86Mn12Ni2], Cupron [Cu53Ni44Mn3] thiab Evanohm.

Tsev neeg Evanohm ntawm cov hlau nickel-chrome alloys [Ni72Cr20Mn4Al3Si1], [Ni73Cr20Cu2Al2Mn1Si], muaj kev tiv taus siab, qhov kub tsis tshua muaj kev tiv taus, lub zog electromotive qis (Galvani muaj peev xwm) thaum sib cuag nrog tooj liab, lub zog tensile siab, thiab tseem ruaj khov heev thaum kho cua sov.
