Titanium is developed in the 1950 s a kind of important structure of the metal, titanium alloy with low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic non-magnetic, welding can be adornment sex is strong, good biocompatibility, surface features, widely used in aviation, aerospace, chemical, petroleum, electric power, medical, construction, sporting goods and other fields. Many countries in the world have realized the importance of titanium alloy materials, have been studied and developed, and has been applied in practice.
Application fields of titanium and titanium alloys:
Aerospace: jet engine components, fuselage components, rockets, satellites, missiles, etc. Compressor and fan blades, discs, casings, guide blades, shafts, landing gear, flaps, choke plates, engine nacelle, bulkheads, wing spars, fuel tanks, boosters.
Chemical, petrochemical industry: used in chlor-alkali, soda, plastic, petrochemical, metallurgy, salt and other industries of electrolytic tank, reactor, steam and general industrial distillation tower, concentrator, separator, heat exchanger, pipe, electrode, etc.
Ship: submarine pressure shell, propeller, water jet propeller, seawater heat exchange system, ship pump (valves and pipes).
Marine engineering: seawater desalination pipelines, offshore oil drilling pumps, valves, pipe fittings, etc.
Biomedical: artificial joints, artificial dental implants and orthodonts, pacemakers, cardiovascular stents, surgical instruments, etc.
Sports equipment: golf head, tennis racket, badminton racket, billiard cue, mountaineering stick, ski pole, skates, etc.
Articles for daily use: eyeglass frame, watch, walking stick, fishing rod, kitchenware, digital product shell, handicraft, decoration, etc.
Construction: roof, exterior walls, decorations, signage, railings, plumbing, etc.
Automobile: exhaust and muffler systems, load-bearing springs, connecting rods, bolts, etc.
In 2011, the global consumption of commercial aviation reached 46%, military titanium accounted for 9%(mainly military aviation), and the overall aviation industry consumption of titanium accounted for more than 50%. 43% of titanium is consumed in industry and 2% in emerging markets.
The demand structure of titanium products has obvious regional differences. In North America and the European Union, especially the United States, where the aerospace and military defense industries are well developed, more than 50% of the titanium product demand comes from the aerospace and military defense sector. In Japan, industrial titanium from industries such as chemicals dominates demand. Aerospace accounts for only 2-3% of Japan's titanium demand, according to the Titanium Association of Japan. Much like Japan, the bulk of China's titanium demand comes from the chemical and energy sectors, with aerospace accounting for only 10 per cent. While China has become one of the world's largest producers and consumers of titanium, much of its production has been confined to lower-grade titanium used in bicycle frames, golf clubs or anti-corrosion pipes used in the chemical industry. However, in recent years, the amount of titanium used in aerospace has increased significantly in Asia, which shows that the titanium market has a bright future.
