Titanium Alloy Classification

By organisation
. (1 titanium in the addition of aluminium and tin elements.2 titanium in the addition of aluminium, chromium, molybdenum and vanadium alloying elements.3 titanium in the addition of aluminium and vanadium and other elements.) Titanium alloy has high strength and low density, good mechanical properties, toughness and corrosion resistance is very good. In addition: titanium alloy process performance is poor, cutting and processing difficulties. In thermal processing, very easy to absorb hydrogen, oxygen, nitrogen, carbon and other impurities. There is also poor wear resistance, complex production process.

According to the mixed elements
Titanium is an alloy composed of other elements. The industrial production of titanium started in 1948. The development needs of the aviation industry, so that the titanium industry to an average annual growth rate of about 8% development. The world annual output of titanium alloy processing material has reached more than 40,000 tonnes, 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).
According to the use of points
Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium - molybdenum, titanium - palladium alloys, etc.), low-temperature alloys, as well as special function alloys (titanium - iron hydrogen storage materials and titanium - nickel memory alloys) and so on. The composition and properties of typical alloys are shown in the table.
