Kukaniza Kwabwino kwa Oxidation NiCr 70/30 kwa Zingwe Zotenthetsera

Kufotokozera Kwachidule:

NiCr 70/30 (2.4658) ndi austenitic nickel-chromium alloy (NiCr alloy) yogwiritsidwa ntchito potentha mpaka 1250°C. Aloyi 70/30 imadziwika ndi kukana kwakukulu komanso kukana kwa okosijeni. Ili ndi ductility wabwino pambuyo ntchito ndi weldability kwambiri.


  • Gulu:NiCr 70/30
  • Kukula:akhoza makonda
  • Mawonekedwe:Kuvula
  • Kutentha kwakukulu (°C):1250
  • Kachulukidwe (g/cm³):8.1
  • Katundu Wamaginito:ayi
