During the 12th Five-Year Plan period, China will focus on developing high-strength light alloy materials. The goal of this project is to achieve major breakthroughs in the development of key new alloy varieties by 2015, forming a production capacity of 300,000 tons of high-end aluminum alloy materials, 20,000 tons of high-end titanium alloy materials, 150,000 tons of high-strength magnesium alloy die-casting, profiles and plates . 2014 was the sprint year for the high-strength light alloy to reach the project goal, and its sprint results are worth looking forward to.
Titanium alloy is a light alloy occupying an important position in modern high-end weapons.
According to data, in recent years, the mass of military aircraft and engine titanium produced in mass production in China has accounted for 25%, while the proportion of F-22 titanium alloy has reached 41%. Titanium metal is widely used in aerospace, chemical, petroleum, electric power and other fields due to its high strength, good ductility, corrosion resistance, and non-magnetic properties.
In addition to titanium alloys, light alloys also include aluminum alloys and magnesium alloys. Aluminum alloys were used earlier and are more popular today, often appearing in fields such as automobiles and ships.
