TITANIUM APPLICATION

itanium alloys have outstanding properties in their ligh strength to weight ratio, exceptional resistance to corrosion, non-magnetics, biocompatibility and resistance to low temperature. Titanium and its alloys have proven to be technically superior and cost-effective materials for a wide variety of aerospace, industrial, marine and commercial applications.

Application//  01
 

Metal Extraction Equipment

Hydrometallurgical extraction of metals from ores in titanium reactors is an environmentally friendly alternative to smelting processes. Extended lifespan, increased energy efficiency and greater product purity are factors promoting the usage of titanium electrodes in electro- winning and electro-refining of copper, gold, manganese and manganese dioxide.

 

 

FGD (Flue Gas Desulphurisation)

Major installations of titanium in the outlet ducts and stacks of FGD plants show the exceptional resistance titanium has to aggressive environments.Fast, cost effective installation techniques have been developed. In life cycle cost studies, titanium linings have proven to be the least expensive option.

 

Sporting Equipment

Titanium golf shafts, tennis racquet frames, pool cue shafts, and bicycle frames are currently being fabricated using alloys such as Ti-3Al-2.5V. These have the properties needed for sports applications:Good strength-to-weight ratiosGood corrosion resistanceLow modulus of elasticityDamage tolerance

 

Food, brewing and pharmaceutical

Titanium demonstrates excellent corrosion resistance, not only to various food products and pharmaceutical chemicals, but also to the cleaning agents utilized. As equipment life becomes a more critical factor in financial evaluations, titanium equipment will replace existing stainless steel apparatus. Outstanding biocompatibility offers new opportunities to the production of developing pharmaceutical products.

 

 

Gas turbine engines

Highly efficient gas turbine engines are possible only through the use of titanium-based alloys in components like fan blades, compressor blades, discs, hubs and numerous rotating parts. The key advantages of titanium- based alloys in this application include high strength/weight ratio, strength at moderate temperatures and good resistance to creep and fatigue. Currently, titanium alloys are available for sustained operation at temperature up to 600°C (1112°F). The development of titanium aluminides will allow the use of titanium in hotter sections of a new generation of engines.

Airframes

Titanium plays a critical role in weight reduction of highly-stressed parts, especially the fuselages and wings. For each ton saved, the resultant savings is 1.5 to 2 tons of added flight revenue.The most important properties titanium offers are high fatigue strength and fracture toughness. Titanium typically comprises 9% by weight of commercial airframes. This percentage is not forecast to diminish even with increasing use of carbon fiber composites. In fact, usage is increasing steadily, replacing high strength steels and aluminum.

 

Anodes

Titanium electrodes coated with precious metal or precious metal oxides are used for:Impressed current cathodic protectionChlorine productionElectroplatingMetal recoveryElectrophoresis and electro-osmosis and other applications where long term electrode stability is required.

 

Heat exchangers

The outstanding corrosion and erosion resistance of titanium provides protection against environmental pollution and contamination of process streams. The advantages titanium offers for plate and tube exchangers are:no need for corrosion allowancesno loss of fatigue strength in seawaterno requirement for corrosion protectionlow fouling factorsTitanium tubes are currently available in several extended surface configurations, including fine integral fin, roped and clad high fin. Design for corrosion resistance and optimum heat transfer with all liquid systems, condensing and evaporating is therefore possible.

 

Dental alloysThe bio-compatibility and strength of titanium make it an ideal material for dental posts and other oral prosthetics. Bone naturally adheres to the surface oxide of titanium without additional coatings.

 

 

 

Marine

Because of high strength, high toughness and exceptional erosion/corrosion resistance, titanium is currently being used for submarine ball valves, fire pumps, heat exchangers, castings, hull materials for deep sea submersibles, water jet propulsion systems, shipboard cooling and piping systems and many other components in ship designs.
