Main Uses Of Titanium Alloys

Titanium alloys are a new and important structural material used in the aerospace industry, with specific gravity, strength and service temperature between aluminum and steel, but with high specific strength and excellent resistance to seawater corrosion and ultra-low temperature performance. Titanium alloys are mainly used to make aircraft engine compressor parts, followed by rockets, missiles and high-speed aircraft structural parts. 60's, titanium and its alloys have been applied in general industry, used to make electrolysis industry electrodes, power station condenser, petroleum refining and seawater desalination of the heater as well as the environmental pollution control devices. Titanium and its alloys have become a corrosion-resistant structural material. It is also used to produce hydrogen storage materials and shape memory alloys.

Titanium alloy has the advantages of light weight, high specific strength, good corrosion resistance, it is widely used in the aviation industry, the application of titanium alloy is the engine system.

The use of titanium alloys to manufacture engine parts has many advantages. The low density of titanium alloy can reduce the inertial mass of moving parts, thus reducing friction and improving engine fuel efficiency. At the same time titanium valve springs can increase free vibration and dampen chatter.

The choice of titanium alloy can reduce the load stress of the relevant parts and reduce the size of the parts, thus reducing the mass of the engine and the whole machine. The reduction of the inertial mass of the parts makes the vibration and noise weaker, improves the performance of the engine, and increases the speed and output power of the engine. The application of titanium alloy in other parts can improve personnel comfort and aesthetics and so on. Titanium alloy plays an immeasurable role in energy saving and consumption reduction.

Titanium alloys have high strength yet low density, good mechanical properties, toughness and corrosion resistance. In addition, the process performance of titanium alloy is poor, cutting and processing difficulties, in the thermal processing, very easy to absorb impurities such as hydrogen, oxygen, nitrogen and carbon. There is also poor abrasion resistance, and the production process is complex. The needs of the aviation industry development, so that the titanium industry to an average annual growth rate of about 8%. At present, the world's annual output of titanium alloy processing materials has reached more than 40,000 tons of titanium alloys, titanium alloy number nearly 30 kinds.

The use of titanium alloy strength, super corrosion-resistant features made of high-strength springs, has been widely used in mattresses and other civilian areas. Through the use of titanium alloy technology in the mattress spring brand, which is a new type of titanium alloy spring, can conform to the body curve, to achieve the unique support effect from soft to hard, from shallow to deep, easy to enjoy a deep sleep. Moreover, after two high-temperature shaping treatments, the spring's elasticity and restoring power are effectively improved, and its durability is enhanced.
