Nicr20alsi Waya / Karma / 6J22Wire fun Resistors
NiCr20AlSi waya/Karma/ 6j22 waya fun Resistors
Karma alloy jẹ ti bàbà, nickel, Aluminiomu ati Iron gẹgẹbi awọn paati akọkọ. Awọn resistivity jẹ 2 ~ 3 igba ti o ga ju Manganin. O ni iye iwọn otutu kekere ti resistance (TCR), EMF igbona kekere dipo bàbà, iduroṣinṣin to dara fun akoko pipẹ ati anti-oxidation lagbara. Iwọn iwọn otutu ti n ṣiṣẹ pọ ju Manganin (-60 ~ 300ºC). O dara fun ṣiṣe awọn eroja resistance to peye ati bankanje igara.
