Ukuxinana yenye yeempawu ezininzi zentsimbi.Ibalwa ngokwahlula ubunzima ngomthamo.Intsimbi iza ngeendlela ezininzi ezahlukeneyo.Uxinaniso lubalwa ngokwahlula ubunzima ngomthamo.Ubuninzi be-carbon steel bumalunga ne-7.85 g / cm3 (0.284 lb / in3).

Zininzi izinto ezisetyenziselwa intsimbi.Insimbi engenasici, umzekelo, isetyenziselwa izixhobo zotyando kunye nekhitshi.Luhlobo lwentsimbi equkethe amanqanaba ekhabhoni aphantsi kwaye ubuncinci i-10.5% yechromium.Oku kubangela ukuxhathisa ukubola.Olunye uhlobo lwensimbi, insimbi yesixhobo, isetyenziselwa izixhobo zokusika isinyithi i-drill bits kuba inzima, kodwa i-brittle.Ubungakanani bekhabhoni kwi-carbon steel bumisela ubulukhuni bentsimbi.I-carbon eninzi iqulethe, iqinile intsimbi.Intsimbi yekhabhoni isoloko isetyenziselwa iinxalenye zemoto.

Intsimbi kunye neendlela zayo ezahlukeneyo zisetyenziswa ngeendlela ezininzi kwihlabathi liphela.Ubume bensimbi buxhomekeke kumxholo wayo, obangela ukuxinana okungafaniyo.Kwiimeko ezininzi, i-denser intsimbi, inzima kakhulu.Izixa ezihlukeneyo zekhabhoni, phakathi kwezinye izinto kwiintlobo zetsimbi zetsimbi zidala ukuxinana okanye ubunzima obuthile.(Ubunzima obuthile okanye ubuninzi obuzalanayo ngumlinganiselo woxinaniso lwemathiriyeli nolo lwamanzi.)

Kukho iindidi ezintlanu eziphambili zeentsimbi: i-carbon steel, i-alloy steel, i-high-high-high-low-alloy steel, insimbi engenasici kunye nesixhobo sensimbi.Iintsimbi zekhabhoni zezona zixhaphakileyo, eziqulathe izixa ezahlukahlukeneyo zekhabhoni, zivelisa yonke into ukusuka koomatshini ukuya kutsho kwiibedsprings ukuya kwizikhonkwane ze-bobby.Iintsimbi ze-alloy zinemilinganiselo ecacileyo ye-vanadium, i-molybdenum, i-manganese, i-silicon kunye ne-cooper.Iintsimbi zealloy zivelisa iigiya, iimela zokukrola kunye nezityibilizi eziqengqelekayo.Iintsimbi ezingenazintsimbi zinechromium, nickel phakathi kwezinye izinto ezigcina umbala wazo kunye nokusabela kwirusi.Iimveliso zensimbi ezingenasici ziquka imibhobho, ii-capsules zendawo, izixhobo zotyando kwizixhobo zasekhitshini.Okokugqibela kodwa okuncinci, izixhobo zentsimbi zine-tungsten, i-molybdenum phakathi kwezinye izinto ze-alloy.Ezi zinto zidala ukomelela kunye nobuchule besixhobo seemveliso zentsimbi, ezibandakanya iinxalenye zemisebenzi yokuvelisa kunye noomatshini.
