Large specifications of high-performance aluminum strip usually refers to the surface quality, dimensional accuracy, version and performance requirements to meet the higher standards of aluminum deep processing products, widely used in transportation (subway, high-speed rail, etc.), aerospace, Marine ships, packaging and other national economic development and national defense construction required key basic materials.
1, the car lightweight
Aluminum alloy is widely used in various parts of the car, such as the instrument panel and engine support, aluminum wheels, suspension parts, bumper anti-collision beams, cylinders, doors and heat exchangers.
Aluminum instead of steel manufacturing cars can reduce the weight of the engine and wheels by about 30%, aluminum radiators (compared with copper products) reduce the weight of 20% to 40%, and the weight of the vehicle is reduced by 30% to 40%. This greatly improves the speed and handling of the car.
2, high-speed rail car body material
More than 85% of the material of a high-speed rail car body is extruded aluminum, and the whole car body is welded by profiles, plates, castings and forgings. High-speed rail cars not only have high requirements for rigid strength, but also have restrictions on the weight of the car. The density of aluminum alloy only accounts for 1/3 of the density of steel, but after adding certain elements to form an alloy, the strength is higher than that of steel alloy, which is naturally the best choice!
Industry experts also pointed out that high-speed trains above 300 km/h must use aluminum alloy materials, and train cars above 350 km use aluminum profiles except for the chassis.
3, aviation equipment manufacturing one of the most important metal materials
At the same strength level, aluminum alloy can provide a thicker section of the material, better buckling resistance under pressure, becoming a classic aircraft structural material. For example, high-strength aluminum alloy thick plates are used as the main load-bearing components, and the proportion of use accounts for 30% to 35% of the total aluminum consumption on the aircraft
