New materials will be introduced second Five-light alloy and steel high-performance power

Among all the strength of titanium metal first, ductility, corrosion resistance, excellent non-magnetic and other properties, is widely used in aerospace, chemical, oil, electricity, desalination, construction, sports and leisure industries, known as the first three metals and strategic metals. According to the U.S. TIE's statistics, in addition to Russia and China, 46% of global titanium demand from the aviation industry, 43% comes from industry, 9% from the military, 2% from emerging markets.

Chinese commercial aircraft self-sufficiency rate is low at present, the aviation industry is relatively backward, aviation demand in the proportion of titanium consumption is only about 10%. In 2010, with the strategy of promoting large aircraft, commercial aircraft into the domestic stage, a conservative calculation, only the field of commercial aircraft to use titanium future size will reach 7.2-18 million tons. The field of military aircraft, the superior performance of the aircraft engine and airframe materials for more demanding, the use of titanium and composite materials, the ratio is also higher. At present, China mass-produced military aircraft quality titanium airframe and engine together accounting for 25%, while the proportion of F-22 titanium or even as high as 41%.

In the field of alloy materials listed companies, Baotaigufen (600 456) and Steel Research Gaona (300034:17.03, -0.38, ↓ -2.18) in the aviation industry in the development of the most obvious benefit. The former cooperation with foreign airlines have been the foundation of aviation titanium leader, once completed the localization of aircraft engines, performance of the company is expected to be explosive growth; the latter is the high-temperature alloys for aerospace important production base for high-temperature alloys in the cast casting, wrought superalloy turbine blades and ODS alloys, protective films in China as a monopoly.

Magnesium is the lightest of all metals, the density of aluminum 2 / 3 Ti 2 / 5, Steel 1 / 4. So when it was used for the automotive industry, in energy-saving and emission reduction will be promising. According to the study, 60 percent of car fuel consumption in vehicle weight, if 10% of car weight, fuel consumption can be reduced by 6% -8%, displacement also will be greatly reduced. Car lighter is the development trend of the automotive industry in Europe after 2011, the depot plans to the factory new car weight loss goal of 7% -8%; 2016 after the further weight loss of 7% -8%.

So far, a total of more than 60 automotive parts magnesium alloy, in which the base instrument panel, seat frames, steering wheel shaft, engine valve covers, transmission housings, intake manifolds, auto body parts such as magnesium alloy 7 the highest utilization rate. Cycling in Europe and the United States use of magnesium alloy parts 5.8-23.6 kg, China's automotive bicycle usage less than 10 kg, similar self-developed car than the average car weight of 8% -10%, while at the same weight, the poor security 2-3 level.
