Na Pono Kino o Constantan

Copper nickel alloy constantan wire, he haʻahaʻa ka uila resisitance, maikaʻi ka wela a me ka corrosion-kū kū'ē, maʻalahi ke hana a me ke alakaʻi welded. Hoʻohana ʻia ia e hana i nā ʻāpana koʻikoʻi o ka relay overload thermal, haʻahaʻa haʻahaʻa haʻahaʻa thermal circuit breaker, a me nā mea uila. He mea koʻikoʻi nō hoʻi ia no ke kaula hoʻomehana uila. Ua like ia me ke 'ano cupronickel.

ʻO nā waiwai kino o constantan:
