TITANIUM ALLOY TUBE PIPE

Titanium alloy refers to a variety of alloy metals made from titanium and other metals. Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance and high heat resistance.

The properties of titanium are related to the content of carbon, nitrogen, hydrogen, oxygen and other impurities contained in titanium, and the impurity content of the purest titanium iodide is not more than 0.1%, but its strength is low and plasticity is high.The properties of 99.5% industrially pure titanium are as follows: density ρ=4.5g/cm3, melting point of 1725℃, thermal conductivity λ=15.24W/(m.K), tensile strength σb=539MPa. Elongation δ=25%, section shrinkage ψ=25%, modulus of elasticity E=1.078×105MPa, hardness HB195.

APPLICATIONS

Titanium alloy has high strength and low density, good mechanical properties, toughness and corrosion resistance. In addition, titanium alloy process performance is poor, cutting and processing difficulties, in hot processing, very easy to absorb impurities such as hydrogen, oxygen, nitrogen and carbon. There is also poor abrasion resistance, the production process is complex. The industrialized production of titanium was started in 1948. The need for the development of the aviation industry, so that the titanium industry to an average annual growth rate of about 8% development. The world's annual output of titanium alloy processing materials has reached more than 40,000 tons, titanium alloy grade nearly 30 kinds. The most widely used titanium alloy is Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).

Titanium alloys are mainly used to make aircraft engine compressor parts, followed by structural parts for rockets, missiles and high-speed aircraft.In the mid-1960s, titanium and its alloys have been applied in general industry to make electrodes for the electrolysis industry, condensers for power stations, heaters for petroleum refineries and seawater desalination as well as environmental pollution control devices, etc. Titanium and its alloys have become a kind of resistant material. 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 alloys are a new important structural material used in the aerospace industry, with specific gravity, strength and service temperature between aluminum and steel, but with higher strength than aluminum and steel and excellent resistance to seawater corrosion and ultra-low temperature performance.
