Txij ntawm qhov pom ntawm qhov chaw pom, nws yog xim hlautitaniumyog nyiaj-grey, zoo ib yam li hlau. Piv nrog cov hlau zoo tib yam, titanium muaj ntau lub zog zoo: tsis tshua muaj ntom thiab muaj zog, thiab tuaj yeem ua tau raws li cov kev xav tau ntawm lub teeb tsa thaum siv nyob rau hauv kev tsim kho. Qhov ntom ntawm titanium yog 4.54g / cm3, uas yog tsuas yog 56% ntawm cov qauv zoo tib yam steel, thiab nws lub zog yog sib npaug los yog siab dua qhov ntawm cov hlau tsis muaj zog.
Hauv cov khoom siv hlau, qhov tshwj xeeb ntawm lub zog ntawm titanium yog qhov siab, thiab kev ua tau zoo ntawm ntau cov hlau alloys zoo heev tom qab ib qho me me ntawm titanium ntxiv. Qhov saum npoo ntawm titanium tau yooj yim tsim cov yeeb yaj kiab oxide nrog cov pa hauv qhov chaw ib puag ncig, uas ua rau nws muaj kev tiv thaiv zoo hauv oxidizing acid, alkali, thiab ntsev xov xwm, tshwj xeeb tshaj yog hauv chlorine thiab dej hiav txwv. Cov tuab ntawm oxide zaj duab xis Sib txawv, xim sib txawv tuaj yeem hloov tau. Vim tias nws muaj zog tiv thaiv xeb, xav txog kev tu ncua lub sijhawm ntev, nws lub sijhawm ntev uas tau siv nyiaj yuav tsis siab tshaj lwm cov hlau, thiab nws yog qhov tshwj xeeb tshaj yog tsim rau cov chaw ib puag ncig xws li seashores, acid los nag, thiab thaj chaw volcanic.
Lub shrinkage coefficient ntawm titanium yog 8.2 × 10-3mm / m ℃ ℃, uas yog ib nrab ntawm qhov ntawd ntawm stainless hlau thiab tooj liab. Nws yog tsim rau siv nyob rau hauv thaj chaw muaj kev hloov pauv kub, thiab yog qhov zoo dua rau cov ntu nrog kev hloov qhov kub thiab txias xws li lub tsev ru tsev. Titanium yog cov khoom siv uas tsis sib txuas, nws lub ntsiab lus melting yog li 1660 ℃, thiab nws tuaj yeem tiv qhov kub siab txog 1100 ℃ hauv kev kuaj hluav taws. Raws li cov txheej txheem cov khoom, titanium alloy muaj ntau lub zog zoo dua li aluminium alloy.
