Titanium and its alloys have proven to be technically superior and cost-effective materials of construction for a wide variety of aerospace, industrial, marine and commercial applications. In North America, approximately 70% of the titanium consumed is utilized for aerospace applications. Due to the expansion of existing applications and the development of new uses, the greatest growth will occur in the industrial, marine and commercial sectors.

 

The properties and characteristics of titanium which are important to design engineers in a broad spectrum of industries are:
Excellent Corrosion Resistance
Titanium is immune to corrosive attack by salt water or marine atmospheres. It also exhibits exceptional resistance to a broad range of acids, alkalis, natural waters and industrial 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 coppernickel alloys.
High Heat Transfer Efficiency
Under "in service" conditions, the heat transfer properties of titanium approximate those of admiralty brass and coppernickel. There are several reasons for this:
Titanium's higher strength permits the use of thinner walled equipment.
There appears to be unusual and beneficial characteristics in titanium's inherent oxide film.
The relative absence of corrosion in media where titanium is generally used leaves the surface bright and smooth for improved lamellar flow.
Titanium's excellent erosion-corrosion resistance permits significantly higher operating velocities.
Superior Strength-to-Weight Ratios
The densities of titanium-based alloys range between .160 Lb/in3 (4.43 gm/cm3) and .175 Lb/in3 (4.85 gm/cm3). Yield strengths range from 25,000 psi (172 MPa) commercially pure (CP) Grade 1 to above 200,000 psi (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. These ratios for titanium-based alloys are superior to almost all other metals and become important in such diverse applications as deepwell tubestrings in the petroleum industry and surgical implants in the medical field.
