Cov Cim Npe Khoom

Cov hlau tiv taus hluav taws xob feem ntau siv rau hauv cov cua sov hluav taws xob, tshwj xeeb tshaj yog NiCr. Nichrome yog nickel thiab chromium alloy uas feem ntau siv rau hauv kev tsim cov hlau tiv taus vim nws qhov siab resistivity thiab ruaj khov anti-oxidation zog ntawm qhov kub txog li 1250 ° C yog vim li cas cov hlau tiv taus zoo-haum rau kev pabcuam hauv qhov chaw kub heev uas lawv raug kev nyuaj siab thiab cua sov. Vladimir Plant ntawm Precision Alloys tau tsim cov hlau tiv taus thiab cov hlau cua sov los ntawm nws lub hauv paus. Peb lub zog yog ua cov hlau, strips, ribbon thiab ntawv ci, suav nrog NiCr alloys thiab Fe-Cr-Al alloys.
