7050 aluminum alloy profile for high speed railway

7050 aluminum alloy has the advantages of low density, high strength, good fracture toughness and strong corrosion resistance. In recent years, it has been widely used in the manufacture of high-speed rail sleepers, aircraft fuselage frames, ship bulkheads and other important structural parts. Extrusion is one of the main forming methods of high-performance 7xxx aluminum alloy, and extrusion speed and temperature are the important process conditions that affect the microstructure and properties of the alloy.

7050 aluminum alloy profile for high speed railway

7050 aluminum alloy profile for high speed railway is a high strength heat treatable alloy with high strength, spalling corrosion resistance and stress corrosion cracking resistance. It is commonly used in the manufacture of key structural parts such as high-speed rail sleepers

7050 aluminum alloy profile for high speed railway is used to manufacture the sleeper beam of high speed railway. The sleeper beam is the key component of the bogie of high speed railway. Its stability and reliability are the necessary conditions for the safe operation of high speed railway. Therefore, the mechanical properties of the sleeper beam profile are very high, and the quality of the weld formed by extrusion of the profile must pass the strict quality inspection, It is very difficult to produce the welding defect
