NiCr Alloy A tsis kam Alloy Sawb Nichrome 8020 NiCr8020 Sawb rau Resistor

Lus piav qhia luv luv:

Cr20Ni80 muaj cov khoom zoo heev. Cov khoom cua kub zoo yuav xaiv Cr20Ni80. Cr20Ni80 muaj qhov zoo ntawm cov pa oxygen zoo, siab zog, tsis muaj hlau nplaum, siab emissivity, zoo corrosion kuj, tsis softening, tsis deformation, thiab tsis tshua muaj elongation. Nickel-chromium, npib tsib xee, ferrochrome alloy hlau nrog hluav taws xob kub oxidation kuj, siab zog, tsis soften thiab ib tug series ntawm zoo. Thaum siv rau lub sijhawm ntev, tib hom thiab qhov elongation mus tas li yog me me, uas yog ntau dua Cr10Ni90 alloy nrog cov khoom zoo heev, yog los tsim cov khoom zoo ntawm cov khoom siv hluav taws xob.
