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.

1.About Nichrome waya
Nichrome alloy imaphatikizapo faifi tambala, NiCr alloy, Fe-Cr-Al alloy ndi copper nickel alloy.
Nickel chrome alloys: Ni80Cr20, Ni70Cr30, Ni60Cr15, Ni35Cr20, Ni30Cr20, Cr25Ni20, nickel Ni200 ndi Ni201
2.Main Phindu ndi Kugwiritsa Ntchito
1. Nickel-chromium, faifi tambala-chromium aloyi ndi kukana mkulu ndi khola, kukana dzimbiri, pamwamba makutidwe ndi okosijeni kukana ndi zabwino, bwino pansi pa kutentha kwambiri ndi mphamvu zivomezi, ductility wabwino, workability wabwino ndi weldability.
2.Zogulitsa zathu zimagwira ntchito kwambiri kumakampani opanga mankhwala, makina opangira zitsulo, mafakitale agalasi, mafakitale a ceramic, malo opangira zida zam'nyumba ndi zina zotero.
