Titanium strength/density ratio is better than other metals, components with

high strength, good rigity, less weight can be made out of titanium. Titanium

is applied for aircrafts engines, frames, skins, fastners and landing gears.

Compared with stainless steel, titanium alloy's corrosion is better in moisture

laden air, seawater, titanium greatly resists spot corrosion, acid corrosion

and stress corrosion. Titanium resists corrosions to alkali, chloride,

chlorinated  organic sunstances, sulphuric acid, nitric acid.

Titanium application temperature's higher than aluminium alloys. Titanium

can work in 450-500℃for long time. Titanium alloy stil prossesses high

strength  when working in 150-500℃. Titanium working temperature can

be reached to 500℃

Titanium alloys still owns its mechanical properties when working in low

or super low temperature  conditions. Titanium alloys with low-temperature

resisitance and extra low interstitial still possess  good ductility, therefore,

titanium alloy is sort of  good low temperature structural material.

Thermal conductivity of titanium is lower than carbon steel or copper,

but titanium owns very good  corrosion resistance, therefore, titanium

thickness can be greatly reduced, also the heat exchange  mode is

dropwise condensation between titanium  and steam. This kind of

mode reduces heat transfer  resistance, no fouling on

titanium  surface, which makes titanium thermal conductivity better.

Titanium is non-magnetic metal, it can't be magnetized in large magnetic

field, also titanium is  toxic-free and compatibility with blood, there,

titanium is applied in medical field.

The elastic modulus of titanium at room temperature is 106.4 GMpa, which is

57% of that of steel.
