Application Area: It is widely used in industrial furnace, household appliances, industry furnace, metallurgy, machinery, aircraft, automotive, military and other industries producing heating elements and resistance elements.
Cov neeg tawm tsam hauv cov ntawv luam tawm hluav taws xob yuav yog ib qho kev sib koom tes rau cov minimiaturizing pob nrog kev ntseeg siab dua thiab txhim kho hluav taws xob. Kev sib xyaw ua ke resistor kev ua haujlwm rau hauv lub tshav puam frees Nickel-chromium alloys muaj hluav taws xob kub tiv thaiv, uas ua rau lawv ua tau rau kev siv ntau yam kev siv. Npib tsib xee thiab chromium yog txuam nrog silicon thiab txhuas los txhim kho qhov kub thiab txias ruaj khov thiab txo cov thermal coefficient ntawm tsis kam. Ib tug nyias zaj duab xis tiv taus txheej raws li Nickel-chromium alloys tau tso tsis tu ncua los tsim cov khoom siv rau cov ntawv thov deasator. Cov duab zaj duab puab nyias ravestive sandwiched ntawm tooj liab thiab laminate tuaj yeem xaiv etched los ua cov defreitors. Cov tshuaj lom rau etching muaj ntau nyob hauv PWM ntau cov txheej txheem. Los ntawm kev tswj cov tuab ntawm cov alloys, ntawv tiv thaiv qhov tseem ceeb los ntawm 25 txog 250 Ohm / sq. yog tau. Daim ntawv no yuav sib piv ob lub npib tsib xee-chromium-chromium cov ntaub ntawv nyob rau hauv lawv cov txheej txheem etching, kev sib dhos, fais fab kev ua tau, thermal kev ua tau zoo, kev daws teeb meem zoo nkauj thiab etching daws teeb meem.
