Chitsulo chachitsulo sichinthu chimodzi koma ndi gawo la gulu la zipangizo zomwe zingathe kupangidwa kuti zikhale ndi katundu wambiri pogwiritsa ntchito microstructure. Chikhalidwe chodziwika bwino cha gulu ili la zipangizo ndi mawonekedwe a graphite. Muzitsulo za ductile, graphite ili mu mawonekedwe a nodule osati ma flakes monga momwe ili mu chitsulo chotuwa. Maonekedwe akuthwa a ma flakes a graphite amapangitsa kuti pakhale kupsinjika kwachitsulo mkati mwazitsulo zachitsulo komanso mawonekedwe ozungulira a tinthu tating'onoting'ono tochepa, motero amalepheretsa kupanga ming'alu ndikupereka ductility yowonjezera yomwe imapatsa aloyi dzina lake. Mapangidwe a tinthu tinatake tozungulira amatheka ndi kuwonjezera nodulizing zinthu, makamaka magnesium (onani magnesium zithupsa pa 1100 ° C ndi chitsulo amasungunuka pa 1500 ° C) ndipo, mocheperapo tsopano, cerium (nthawi zambiri mu mawonekedwe a Mischmetal). Tellurium imagwiritsidwanso ntchito. Yttrium, yomwe nthawi zambiri imakhala chigawo cha Misch zitsulo, idaphunziridwanso ngati nodulizer yotheka.
