Enamelled CuNi45/CuNi44/CuNi40 Copper nickel Alloy Waya
Enamelled CuNi45/CuNi44/CuNi40 Alloy Waya
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

Kugwiritsa ntchito Constantan
Constantan ndi aloyi yamkuwa-nickel yomwe imakhala ndi zowonjezera zochepa
zinthu kuti zikwaniritse zofunikira zenizeni za kutentha kokwanira kwa resistivity.Samalani
kuwongolera kusungunula ndi kutembenuka kumapangitsa kuti pakhale mapini otsika kwambiri
zonenepa kwambiri.Alloy imagwiritsidwa ntchito kwambiri popanga zotchingira zojambulazo komanso zoyezera zovuta.
