cóimhiotal elcctrilyheating alúmanaim cróimiam imn. Cóimhiotal téite leictrialach alúmanaim Cróimiam. Bain úsáid as ceann de na cóimhiotail leictriteirmeacha is éadroime. Tá tréithe friotachas mór aige, comhéifeacht friotaíochta teocht beag, friotaíocht maith ocsaídiúcháin agus teocht ard (1400 céim).
Comhdhéanamh ceimiceach: GB/T1234-95
