NiCr20AlSi waea/Karma/6j22 waea mo nga parenga
Ko te koranu Karma he parahi, he nickel, he konumohe me te rino hei waahanga matua. Ko te parenga he 2~3 wa teitei ake i te Manganin. He iti ake te whakarea pāmahana o te ātete (TCR), te iti o te EMF waiariki ki te parahi, he pai te pumau o te aukati mo te wa roa me te kaha anti-oxidation. Ko te awhe pāmahana mahi he whanui ake i te Manganin (-60~300ºC). He pai mo te hanga i nga huānga parenga pai me te pepa riaka.
