Titanium Alloys

At NeoNickel, we offer a range of Titanium alloys that provide high strength-to-weight ratio and outstanding resistance to corrosion in the harshest working environments.

With half the density of nickel alloys, stainless alloys and duplex / super duplex alloys, titanium offers a significant cost to weight ratio for key applications in markets which include : Aerospace, Oil & Gas, FPSO production vessels (floating production storage and offloading vessels), Power Generation, Desalination, Chemical Process, Bio-Medical, Motor Sport, Sports Equipment and many other markets where material performance is critical.

Titanium alloys are also selected based on their high strength, corrosion resistance and high-temperature properties i.e. resistance to oxidation, creep, fatigue and stress-rupture failure.

There is no doubt that Titanium and its alloys play a major part in the Aerospace, Oil & Gas, Chemical Process, Power Generation, Desalination, Bio-Medical, Motorsport and Sporting Equipment industries.

Key properties of Titanium and its alloys are:

  • Low density (relatively light-weight)
  • Exceptional erosion and erosion-corrosion resistance
  • High fatigue strength in air and Chloride environments
  • High fracture toughness in air and Chloride environments
  • Low modulus of elasticity
  • Low thermal expansion coefficient
  • High melting point
  • Excellent cryogenic properties
  • Non-magnetic property
  • High intrinsic shock resistance
  • High ballistic resistance-to-density ratio
  • Nontoxic, non-allergenic and fully biocompatible
  • Very short radioactive half-life

Titanium alloy applications:

  • Motorsport-fasteners
  • Power generation – surface condensers, condenser tubing, plate heat exchangers, turbines, cryogenic vessels
  • Oil & gas – Shell and tube heat exchangers, plate heat exchangers, piping systems, valves and pumps, prop shafts, propellers, cryogenic vessels
