High-end aluminum alloy applications high-end.High-performance aluminum alloy is an important lightweight and high-strength structural material with high tensile strength, toughness and corrosion resistance.In recent years, high-performance aluminum alloy has been widely used in aviation industry, ship, nuclear energy and civil industry, and has become one of the main structural materials in aviation industry, effectively promoting the development of China's national defense.
The domestic aviation market has huge potential.China's aviation market is huge, with 2,218 large and medium-sized aircraft on the books in 2014, almost completely monopolized by Boeing and airbus.Avic, comac, Boeing, airbus and other companies predict that China will add about 5,000 new large and medium-sized civil airliners in the next 20 years, worth about $800 billion.

Aluminum-lithium alloy leads the development of aviation technology domestic and the United States and Russia are still 30 years behind.Lithium can reduce the density of aluminum and increase the modulus of elasticity.For every 1% of lithium added to the metal, the density of aluminum decreases by about 3% and its elastic modulus increases by about 6%, making it a strong competitor to composites (CFRP).According to Boeing aircraft company tests, using aluminum-lithium alloy to make Boeing aircraft can reduce its weight by 14.6 percent, save 5.4 percent on fuel, reduce aircraft manufacturing costs by 2.1 percent, and reduce annual flight costs per aircraft by 2.2 percent.Since the cost of al-li alloys is only about 10% of that of composites (CFRP), they have a significant comparative advantage in applications.

The civilian shipping sector is in hot demand.Passenger transport, leisure tourism, official business law enforcement and other boat market aluminum alloy demand is more robust.For example, passenger ships are in urgent need of upgrading, and the market scale is very large. There are about 180 coastal passenger terminals in China, mainly distributed in hainan, shandong, guangdong, zhejiang, liaoning, fujian, jiangsu and other provinces.The total number of all aluminum alloy high-speed passenger ships in these areas is about 30.If the unit price of each ship construction is calculated at 50 million yuan, the potential ship upgrade market capacity is 1.8 billion yuan.In addition, yacht and official ship market demand is also very big, like aluminum alloy "mini cruise" and aluminum alloy super luxury yacht market in about 2.6 billion yuan, aluminum alloy high-speed law enforcement ship market even in about 20 billion yuan.
