1Cr13Al4 FeCrAl alloy Bright Flat Strip / Wide Strip for Resistors Ntchito

Ma Fecral Alloys ndi Nickel-chromium alloys asankhidwa kuti akhale zinthu zotsutsana ndi zopinga zomizidwa chifukwa ma aloyi a nickel-chromium ali ndi mphamvu yamagetsi yamagetsi yomwe imagwiritsidwa ntchito kwambiri poletsa mafilimu opyapyala [1, 2].Kukaniza kwa pepala la nickel-chrome alloy film yomwe ili ndi 20% chromium imatha kukhala yokwera mpaka 2-3 kilo ohms ndikukhalabe okhazikika.Kutentha kokwanira 1 of resistance (TCR) kwa aloyi wochuluka wa nickel-chrome ndi pafupifupi 110 ppm/°C.Pophatikiza kachitsulo kakang'ono ka silicon ndi aluminiyamu ndi faifi tambala-chromium, kukhazikika kwa kutentha kumakhala bwino.

Ntchito:
Resistors ophatikizidwa mu bolodi losindikizidwa la mawaya adzakhala chothandizira kuti mapaketi ang'onoang'ono azikhala odalirika kwambiri komanso magwiridwe antchito amagetsi.Kuphatikizira ntchito yotsutsa mu gawo la laminate kumamasula malo a PWB omwe amadyedwa ndi zigawo zosiyana, zomwe zimapangitsa kuti chipangizochi chizigwira ntchito kwambiri poyika zinthu zambiri zogwira ntchito.Nickel-chromium alloys ali ndi mphamvu yolimbana ndi magetsi, zomwe zimawapangitsa kuti azigwiritsidwa ntchito mosiyanasiyana.Nickel ndi chromium zimaphatikizidwa ndi silicon ndi aluminiyamu kuti kutentha kukhazikike komanso kuchepetsa mphamvu yamafuta yokana.Chingwe chopyapyala cholimbana ndi filimu chozikidwa pa ma aloyi a nickel-chromium chayikidwa mosalekeza pamipukutu yazojambula zamkuwa kuti apange zinthu zomangira zopinga.Chigawo chopyapyala cholimbana ndi filimu chomwe chili pakati pa mkuwa ndi laminate chikhoza kukhazikitsidwa mwachisawawa kuti chipange zopinga.Mankhwala opangira etching ndiwofala munjira zopangira PWB.Poyang'anira makulidwe a aloyi, kukana kwa pepala kumayambira 25 mpaka 250 ohm/sq.amapezedwa.Pepalali lifanizira zida ziwiri za nickel-chromium pamakina awo, kufanana, kagwiridwe ka mphamvu, magwiridwe antchito amafuta, kumamatira ndikusintha kwa etching.
