Zoponya Zitsulo Zosapanga dzimbiri, Kuponyera kwa Iron Imvi, Kuponyera kwa Iron Ductile

Chitsulo Chotsika cha Aloyi Chogwiritsidwa Ntchito Poponya Zigawo

Low aloyi kuponyedwa zitsulo amatanthauza aloyi kuponyedwa zitsulo ndi mpweya zili zosakwana 0.45% ndi okwana zili zinthu zina aloyi osapitirira 5%. Chitsulo chotsika cha alloy chili ndi mphamvu zambiri, kulimba kwabwino komanso kulimba. Chitsulo chotsika cha alloy chimakhala ndi zinthu zophatikizira monga manganese, chromium, mkuwa, faifi tambala, molybdenum, ndi vanadium. Amakhala ndi mphamvu zokulirapo ndipo amatha kupeza zinthu zamakina abwinoko kudzera mu chithandizo cha kutentha. Kukana kwa dzimbiri ndi kukana kuvala kwa chitsulo chotsika cha alloy ndikwabwino kuposa chitsulo cha kaboni, chomwe chingachepetse kulemera kwa magawo ndikuwonjezera moyo wautumiki.
