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

Fecral Alloys neNickel-chromium alloys akasarudzwa kuti ave zvinhu zvinodzivirira kune zvakamisikidzwa resistor nekuti nickel-chromium alloys ane yakakwirira magetsi resistivity ayo anoshandiswa zvakanyanya kune matete firimu resistors [1, 2]. Pepa rekudzivirira renickel-chrome alloy firimu rine 20% chromium rinogona kukwira se2-3 kilo ohms uye richiramba rakagadzikana. Tembiricha coefficient 1 yekuramba (TCR) yehuwandu nickel-chrome alloy ingangoita 110 ppm/°C. Nekubatanidza chidimbu chidiki chesilicon nealuminium ine nickel-chromium, kugadzikana kwetembiricha kunowedzera kuvandudzwa.

Application:
Resistors akaiswa mune yakadhindwa wiring board ichave inogonesa miniaturizing mapakeji ane kuvimbika kwepamusoro uye nekuvandudzwa kwemagetsi. Kubatanidza iyo resistor performance mu laminate substrate inosunungura nzvimbo yePWB inopedzwa ne discrete components, zvichiita kuti kuwedzerwa kwechishandiso chishande nekuiswa kwezvimwe zvinoshanda zvinoriumba. Nickel-chromium alloys ane yakakwirira yemagetsi resistivity, iyo inoita kuti ishande kushandiswa mumhando dzakasiyana dzekushandisa. Nickel uye chromium zvakasanganiswa nesilicon nealuminium kunatsiridza kugadzikana kwetembiricha uye kudzikisa thermal coefficient yekuramba. Imwe firimu yakatetepa inodzivirira yakavakirwa pane nickel-chromium alloys yakaiswa nguva dzose pamapumburu emhangura foil kugadzira zvinhu zveyakamisikidzwa resistor application. Iyo yakatetepa firimu resitive layer yakamisikidzwa pakati pemhangura uye laminate inogona kusarudzwa yakarongedzwa kuti iite discrete resistors. Iwo makemikari etching akajairika muPWB maitiro ekugadzira. Nekudzora ukobvu hwema alloys, shizha kuramba kukosha kubva pa25 kusvika 250 ohm/sq. zvinowanikwa. Iri bepa rinofananidza maviri nickel-chromium zvinhu mune yavo etching nzira, kufanana, simba rekubata, mashandiro ekupisa, adhesion uye etching resolution.
