Kukula kokhazikika kwa waya wa Nickel alloy:

Timapereka zinthu zowoneka ngati waya, waya wosalala, strip.

Waya wowala ndi woyera-0.025mm ~ 3mm

Pickling waya: 1.8mm ~ 10mm

Waya okosijeni: 0.6mm ~ 10mm

Lathyathyathya waya: makulidwe 0.05mm ~ 1.0mm, m'lifupi 0.5mm ~ 5.0mm

Njira:

Waya:Kukonza zinthu→kusungunula→kusungunulanso→kumanga→kugudubuzikakutentha→mankhwala otentha

Zogulitsa za waya wa nichrome:

1) Anti-oxidation yabwino kwambiri komanso mphamvu zamakina pa kutentha kwakukulu;

2) High resistivity ndi otsika kutentha coefficient kukana;

3) Reelability bwino ndi kupanga ntchito;

4) Kuchita bwino kwambiri kwa kuwotcherera

Kugwiritsa ntchito magiredi onse:
