Simintin ƙarfe na magnesium ya dace da allunan kayan aikin mota, firam ɗin kujerun mota, gidajen gearbox, kayan aikin sarrafa sitiyari, sassan injin, firam ɗin ƙofa, cibiyoyin ƙafafun, maƙallan maƙallan, gidajen kama da maƙallan jiki.

Haɗin titanium

Ana haɗa ƙarfe na titanium sabon nau'in kayan gini ne, yana da kyawawan halaye masu kyau, kamar ƙarancin yawa, ƙarfi mai yawa da taurin karyewa, ƙarfin gajiya mai kyau da juriyar ci gaban fashewa, ƙarfin juriya mai kyau na ƙarancin zafin jiki, juriya mai kyau na tsatsa, wasu ƙarfe na titanium. Matsakaicin zafin aiki shine 550°C kuma ana sa ran zai kai 700°C. Saboda haka, ana amfani da shi sosai a fannin sufurin jiragen sama, sararin samaniya, motoci, gina jiragen ruwa da sauran masana'antu kuma ya bunƙasa cikin sauri.

Gilashin titanium sun dace da ƙera maɓuɓɓugan dakatarwa na motoci, maɓuɓɓugan bawul da bawul. Idan aka kwatanta da ƙarfe mai ƙarfi mai ƙarfin 2100MPa, amfani da ƙarfe mai titanium don yin maɓuɓɓugan ganye na iya rage nauyin da ya mutu da 20%. Haka kuma ana iya amfani da ƙarfe mai titanium don ƙera ƙafafun, kujerun bawul, sassan tsarin shaye-shaye, kuma wasu kamfanoni suna ƙoƙarin amfani da faranti na titanium tsarkakakku azaman bangarorin waje na jiki. Toyota ta Japan ta ƙera kayan haɗin da aka yi da titanium. Ana samar da kayan haɗin ta hanyar ƙarfe foda tare da ƙarfe mai Ti-6A1-4V azaman matrix da TiB azaman ƙarfafawa. Kayan haɗin yana da ƙarancin farashi da aiki mai kyau, kuma an yi amfani da shi kusan a cikin sandunan haɗin injin.
