Ni80Cr20 Hlau tiaj tiaj Nickel Chrome Alloy Rau Cov Khoom Siv Cua Sov

Cov hlau Nichrome 8020 tiaj tiaj, nrog rau 70% nickel thiab 30% chromium, yog cov khoom siv tshwj xeeb. Nws cov qauv tiaj tiaj muaj thaj chaw loj dua, ua kom cov cua sov ua haujlwm zoo thaum tswj hwm qhov kub thiab txias zoo heev. Muaj lub zog hluav taws xob siab, nws zoo meej rau cov khoom siv cua sov hauv cov khoom siv hauv kev lag luam, qhov cub, thiab lwm yam kev siv kub thiab txias. Ua tsaug rau nws txoj kev tiv thaiv oxidation thiab lub zog kho tshuab, cov hlau tiaj tiaj no ua kom muaj kev ua haujlwm tas mus li thiab lub neej ntev, ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov haujlwm cua sov thiab tiv taus.
