Nicr30/20 Alloy Wire High kutentha aloyi
Ni30Cr20Waya wa Nichrome wa Resistance Wire, Resistance Heating Strip
Ntchito: Nichrome, aloyi wosagwiritsa ntchito maginito wa faifi tambala ndi chromium, amagwiritsidwa ntchito popanga waya wokana.
Chifukwa ali ndi resistivity mkulu ndi kukana makutidwe ndi okosijeni pa kutentha kwambiri.Akagwiritsidwa ntchito ngati chinthu chotenthetsera, waya wotsutsa nthawi zambiri amawomberedwa m'makoyilo.
Waya wa Nichrome nthawi zambiri amagwiritsidwa ntchito muzoumba ngati chothandizira mkati kuti athandizire zinthu zina zazosema dongo kuti zisunge mawonekedwe ake akadali ofewa.Waya wa Nichrome umagwiritsidwa ntchito chifukwa chokhoza kupirira kutentha kwakukulu komwe kumachitika pamene ntchito yadongo imawotchedwa mu ng'anjo.

Ntchito:
1. Amagwiritsidwa ntchito m'makampani ophulika ndi zozimitsa moto ngati bridgewire pamakina oyatsira magetsi.
2. mafakitale ndi chizolowezi otentha waya thovu odula.
3. Kuyesa mtundu wa lawi mu gawo lopanda kuwala la cation.
4. Amagwiritsidwa ntchito muzoumba monga chothandizira mkati.
Kupaka: Pali mitundu ingapo yamapaketi osinthika omwe angagwirizane ndi zomwe mukufuna.
