Nickel Chromium NiCr Alloy
Nickel-chromium zvinhu zvinoshandiswa zvakanyanya mumaindasitiri emagetsi emagetsi, midziyo yemumba, kure-infrared zvishandiso uye zvimwe midziyo nekuda kwekusimba kwazvo kwekushisa kwekushisa uye purasitiki yakasimba. Nickel-chromium nesimbi, aluminium, silicon, kabhoni, sarufa uye zvimwe zvinhu zvinogona kugadzirwa kuita nickel-chromium alloy waya, ine yakakwirira resistivity uye kupisa kupisa uye ndiyo yemagetsi kupisa chinhu chechoto chemagetsi, simbi yemagetsi, simbi yemagetsi uye. zvimwe zvigadzirwa.
Uye zvakare, NiCr waya inowanzo shandiswa mucoil yekutsvedza rheostat kuchengetedza dunhu uye kushandura yazvino mudunhu nekushandura kupikisa kwechikamu chedunhu rekupinda, nekudaro ichichinja voltage pane conductor (chishandiso chemagetsi) chakabatana munhevedzano ne. iyo, Inoshandiswa zvakanyanya munhamba huru yemidziyo yemumba.
NiCr Alloy Series
Ni90Cr10 strip imhando yezvigadzirwa zve nickel-chromium alloy, inokodzera kushandiswa kwetembiricha inosvika 1250 ° C. Chromium yemukati inopa hupenyu hwakanaka kwazvo nguva, inowanzo shandiswa sechinhu chekudziya chevape.
Ni90Cr10 inoratidzirwa nepamusoro resistivity, yakanaka oxidation kuramba, yakanaka ductility mushure mekushandisa uye yakanakisa weldability. NiCr Alloy chinhu chakanaka chekudziya indasitiri.
Ni90Cr10 Nickel-Chromium Nickel NiCr Alloy kuramba kupisa foil strip
