Density chimwe chezvinhu zvakawanda zvesimbi.Inoverengwa nekupatsanura huwandu nehuwandu.Simbi inouya nenzira dzakasiyana siyana.Density inoverengerwa nekupatsanura huremu nehuwandu.Kuwanda kwekabhoni simbi kunosvika 7.85 g/cm3 (0.284 lb/in3).

Pane zvakawanda zvekushandisa kwesimbi.Simbi isina tsvina, semuenzaniso, inoshandiswa pamidziyo yekuvhiya uye midziyo yemukicheni.Imhando yesimbi ine yakaderera kabhoni mazinga uye inokwana 10.5% yechromium.Izvi zvinoita kuti pave nekusaora.Imwe mhando yesimbi, chishandiso simbi, inoshandiswa kugadzira simbi yekucheka maturusi mabhiti ekubooresa nekuti yakaoma, asi ine brittle.Huwandu hwekabhoni musimbi yekabhoni inosarudza kuoma kwesimbi.Iyo yakawanda kabhoni iyo ine, iyo inowedzera kuoma kwesimbi.Carbon simbi inowanzo shandiswa kune zvikamu zvemotokari.

Simbi uye mafomu ayo akasiyana ane akawanda mashandisirwo kutenderera pasirese.Chimiro chesimbi chinoenderana nezviri mukati mayo, izvo zvinoguma nekusiyana densities.Kazhinji, iyo denser iyo simbi, iyo yakanyanya kuoma.Kusiyana kwehuwandu hwekabhoni, pakati pezvimwe zvinhu mune imwe neimwe yemhando dzesimbi zvinogadzira zvakasiyana-siyana mu densities kana chaiyo giravhiti.(Specific gravity kana hama density ireshiyo yehuwandu hwechinhu kune iyo yemvura.)

Pane zvikamu zvishanu zvakakura zvesimbi: kabhoni simbi, alloy simbi, yakakwirira-simba yakaderera-alloy simbi, Stainless simbi uye mudziyo simbi.Carbon steels ndiyo inonyanya kuwanda, ine huwandu hwakasiyana hwekabhoni, inoburitsa zvese kubva kumichina kusvika kumabhedha kusvika kumapini ebhobho.Alloy masimbi ane huwandu hwakajeka hwevanadium, molybdenum, manganese, silicon uye cooper.Alloy simbi inogadzira magiya, mapanga ekuveza uye kunyange roller skates.Simbi dzisina simbi dzine chromium, nickel pakati pezvimwe zvinhu zvealloy izvo zvinochengetedza ruvara rwazvo uye kuita ngura.Zvigadzirwa zvesimbi zvisina tsvina zvinosanganisira mapaipi, macapsules emuchadenga, midziyo yekuvhiya kumidziyo yekicheni.Chekupedzisira asi chisiri chidiki, masimbi emidziyo ane tungsten, molybdenum pakati pezvimwe zvinhu zvealloy.Zvinhu izvi zvinogadzira kusimba uye kugona kwechigadzirwa chesimbi zvigadzirwa, izvo zvinosanganisira zvikamu zvekugadzira mashandiro pamwe nemichina.
