Nickel Chromium AlloyNi80cr20 Flat Hlau Kub Element
Ni80Cr20 yog npib tsib xee-chromium alloy (NiCr alloy) Nws tuaj yeem tsim cov xim zoo sib xws nrog cov tshuab zoo heev, hluav taws xob conductivity thiab kub oxidation tsis kam mus txog 1800 degrees F (980 degrees C), thiab nws tuav lub neej kev pabcuam zoo dua piv rau Hlau chromium alumium alloys.Nws nthuav tawm exothermic cua sov thaum siv
Daim ntawv thov:
Cov ntawv thov rau Ni80Cr20 yog hluav taws xobcua sov ntsiabs nyob rau hauv cov khoom siv hauv tsev, kev lag luam furnaces thiab resistors (wirewound resistors, hlau zaj duab xis resistors), tiaj tus hlau, ironing tshuab, dej rhaub, yas molding tuag, soldering hlau, hlau sheathed tubular ntsiab thiab cartridge ntsiab.
