NiCr Alloy A tsis kam Alloy Strip Nichrome 8020 NiCr8020 Strip rau Resistor Featured Duab

NiCr Alloy Ib qho tsis kam Alloy Strip Nichrome 8020 NiCr8020 Strip rau Resistor

Kev Piav Qhia Luv:

Cr20Ni80 muaj cov khoom zoo heev. Cov khoom cua sov zoo yuav xaiv Cr20Ni80. Cr20Ni80 muaj qhov zoo ntawm kev tiv taus oxygen zoo, lub zog siab, tsis muaj hlau nplaum, emissivity siab, tiv taus corrosion zoo, tsis muaj softening, tsis deformation, thiab elongation tsawg tas mus li. Nickel-chromium, nickel, ferrochrome alloy hlau nrog hluav taws xob kub siab oxidation tsis kam, lub zog siab, tsis softening thiab ntau yam zoo. Thaum siv ntev, tib hom thiab elongation tas mus li yog me heev, uas yog ntau dua Cr10Ni90 alloy nrog cov khoom zoo heev, yog los tsim cov khoom zoo rau cov khoom hluav taws xob.
