Nicr20sitil wire /Karma/ 6j22 silig oo loogu talagalay caabiyaha
Karma alkoy waxay ka kooban tahay naxaas, nikkel, aluminium iyo birta sida qaybaha ugu waaweyn. Cadaadiska waa 2 ~ 3 jeer ka sareeya Manganin. Waxay leedahay isbarbardhiga heerkulka hoose ee caabbinta (TCR), EMF-ga hoose ee kuleylka hoose, jiritaanka wanaagsan ee caabbinta muddo dheer iyo anti-anti-ockidis. Heerkeeda heerkulka ah wuxuu ka ballaaran yahay Manganin (-60 ~ 300ºC). Waxay ku habboon tahay sameynta walxo iska caabbinta saxda ah iyo foil adag.
