Constantan Physical Properties

Waya wa nickel alloy constantan, womwe umakhala ndi mphamvu yochepa yamagetsi, yabwino yosamva kutentha komanso yosamva dzimbiri, yosavuta kukonzedwa komanso kuwotcherera. Amagwiritsidwa ntchito popanga zida zazikulu muzowonjezera zotenthetsera matenthedwe, kutsika kwapang'onopang'ono kwamagetsi, ndi zida zamagetsi. Ndichinthu chofunikiranso pazingwe zamagetsi zamagetsi. Ndizofanana ndi 's type cupronickel.

Zinthu zakuthupi za constantan ndi:
