Titanium alloy tube kev ua tau zoo: titanium alloy raj yog ib hom tshiab ntawm cov hlau, kev ua haujlwm ntawm titanium muaj feem xyuam rau cov ntsiab lus ntawm carbon, nitrogen, hydrogen, oxygen thiab lwm yam impurities, cov ntsiab lus ntshiab titanium iodide impurity tsis tshaj 0 .1%, tab sis nws lub zog yog tsawg, siab plasticity. Cov khoom ntawm 99.5% kev lag luam ntshiab titanium yog: ceev ρ=4.5g / cubic centimeter, melting point 1725 degree, thermal conductivity λ=15.24W / (mK), tensile zog σb {{9} }MPa, elongation δ=25%, seem shrinkage ψ=25%, elastic modulus E=1.078 × 105MPa, hardness HB195
