Hai-Nicr70 ca hlaurauOb Chav Sawb Chev Braking resistor

Ni70CR30yog npib tsib xee-chromium alloy (NICR Alloy (NICR Alloy (NICR Alloy (NICR Alloy (NICR ALLOY) tus cwj pwm los ntawm high resistivity, zoo oxidation tsis kam thiab zoo heev daim ntawv ruaj khov. Nws yog qhov haum rau kev siv nyob rau ntawm qhov kub txog 1250 ° C, thiab tuav ib lub neej zoo tshaj piv rau cov hlau chromium alumium alumics.
Cov ntawv thov raug rau NI70CR30 yog hluav taws xob cua sov cov ntsiab lus hauv cov khoom siv hauv tsev, tshuab raj, tshuab ntxhua khaub ncaws, cov tshuab yas dhos, cov hlau nplaum, cov hlau nplaum ua thiab cartridge ntsiab.
