The advantage of titanium

Excellent Corrosion Resistance

Titanium is resistant to corrosive attack by salt water or marine atmospheres. It also exhibits exceptional resistance to a broad range of acids, alkalis, natural waters and chemicals.


Superior Erosion Resistance

Titanium offers superior resistance to erosion, cavitation or impingement attack. Titanium is at least twenty times more erosion resistant than the copper-nickel alloys.


High Heat Transfer Efficiency

Under "in service" conditions, the heat transfer properties of titanium approximate those of admiralty brass and copper-nickel. There are several reasons for this:

(1) Titanium's higher strength permits the use of thinner walled equipment.
(2) There appear to be unusual and beneficial characteristics in titanium's inherent oxide film.
(3) The relative absence of corrosion in media where titanium is generally used leaves the surface bright for improved lamellar flow.
(4) Titanium's excellent erosion-corrosion resistance permits significantly higher operating velocities.


Superior Strength-to-Weight Ratios

The densities of titanium-based alloys range between 4.43 gm/cm3 and 4.85 gm/cm3. Yield strengths range from 172 MPa commercially pure (CP) Grade 1 to above 1380 MPa for heat treated beta alloys.
The combination of high strength and low density results in exceptionally favorable strength-to-weight ratios for titanium-based alloys are superior to almost all other metals. For further reading please look at
