Hai-Nicr70 Flat HlaurauOb Chav Strip Coils Braking Resistor

Ni70Cr30yog ib qho nickel-chromium alloy (NiCr alloy) uas muaj kev tiv thaiv siab, zoo oxidation kuj thiab zoo heev daim ntawv stability. Nws yog qhov tsim nyog rau kev siv ntawm qhov kub txog li 1250 ° C, thiab tuav lub neej kev pabcuam zoo dua piv rau Hlau chromium alumium alloys.
Tej daim ntawv thov rauNi70Cr30yog cov khoom siv hluav taws xob cua sov hauv cov khoom siv hauv tsev, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob (wirewound resistors, hlau zaj duab xis resistors), tiaj tus hlau, ironing tshuab, dej rhaub, yas molding tuag, soldering hlau, hlau sheathed tubular ntsiab lus thiab cartridge ntsiab.
