Aluminum and aluminum alloy seamless pipes are used in aviation industry, electric power, petrochemical industry, grain and oil machinery, automobile air conditioners, tent pillars, refrigeration, agricultural sprinkler irrigation, pressure vessels, etc.
Because it has the characteristics of environmental protection, safety, beauty, earthquake resistance, wear resistance, corrosion resistance, etc., and has good characteristics such as light weight, high specific strength, resistance to stretching, compression, bending, impact, and collision, it is used in the construction of the national economy. Indispensable and irreplaceable structural parts, non-structural parts and decorative materials.
The proposal of the "Made in China 2025" strategy further clarifies the goal of developing large aircraft. Box 5 in "Made in China 2025" in the high-end equipment innovation project (6) Vigorously promote the breakthrough development in key areas. It is necessary to "speed up the development of large aircraft, start the development of wide-body passenger aircraft in due course, encourage international cooperation in the development of heavy helicopters; promote the industrialization of trunk and regional aircraft, helicopters, unmanned aerial vehicles, and general aircraft.
As the key structural material of the aircraft's main oil circuit, aluminum tubing for aircraft fuel line must catch up with the world's advanced level to ensure the development of various fields in the country. Henan Chalco's aluminum processing equipment level, in terms of rolling equipment, three-high rolling has begun to replace two-high rolling, and the accuracy of product quality control has been greatly improved. New alloy grades such as 2017A, 2D12, 5B02, 7075, and 7A09 have been added, which are widely used in the development of aerospace, pressure vessel, electrical and other related industries.
