Mafotokozedwe Akatundu
Mawaya okana awa a enameled akhala akugwiritsidwa ntchito mofala ngati zopinga wamba, magalimoto
mbali, mapiringidzo resistors, etc. ntchito kutchinjiriza processing koyenera kwambiri ntchito zimenezi, kutenga mwayi wapadera wa enamel ❖ kuyanika.
Kuphatikiza apo, tidzapanga zokutira za enamel za waya wamtengo wapatali wachitsulo monga siliva ndi waya wa platinamu polamula. Chonde gwiritsani ntchito kupanga-pa-oda.
Mtundu wa waya wopanda Alloy
Aloyi titha kuchita enamelled ndi Copper-nickel aloyi waya, Constantan waya, Manganin waya. Kama Waya, NiCr Aloyi waya, FeCrAl Aloyi waya etc aloyi waya
