Lapho siphonsa insimbi empunga, silandela ngokuqinile ukwakheka kwamakhemikhali nezakhiwo zemishini ngokuya nge-stardard noma izidingo ezivela kumakhasimende. Ngaphandle kwalokho, sinekhono nemishini yokuhlola ukuthi ngabe kukhona ukushiyeka okusakazayo ngaphakathi kwe-ukukhishwa kwesihlabathi sensimbi okumpunga.
Ama-alloys ayisiqulatho anokuqukethwe kwekhabhoni okungaphezu kuka-2% abizwa ngokuthi izinsimbi. Yize izinsimbi zokuphonsa zingaba nephesenti lekhabhoni phakathi kuka-2 kuye ku-6.67, umkhawulo osebenzayo uvamise ukuba phakathi kuka-2 no-4%. Lokhu kubalulekile ikakhulukazi ngenxa yezimfanelo zabo ezinhle zokulingisa.
Ukufakwa kwensimbi okumpunga zishibhile kune-ductile iron castings, kepha inamandla amancane kakhulu okuqina nokuqina kunensimbi ye-ductile. Insimbi empunga ayikwazi ukumiselela insimbi yekhabhoni, kuyilapho i-ductile iron ingathatha indawo yensimbi yekhabhoni esimweni esithile ngenxa yamandla aphezulu wokuqina, amandla wokukhiqiza nokunwebeka kwensimbi ye-ductile.
Kusukela kumdwebo we-iron-carbon equilibrium, kungabonakala ukuthi izinsimbi ezine-cementite ne-ferrite empeleni. Ngenxa yephesenti elikhudlwana lekhabhoni, inani le-cementite liphezulu okuholela ebukhuni obuphakeme kakhulu nezimfanelo zokuthamba zensimbi eyakhiwe.
