The application of aluminum in transportation field can not only lose weight and improve fuel efficiency, but also reduce greenhouse gas emissions. By selecting light materials, the characteristics of the materials can achieve the purpose of weight loss; in addition, the weight of the car body can be further reduced by using some processing techniques for the parts and components. For example, more complex metal aluminum porous extrusion parts, or high strength thin-wall vacuum aluminum die castings, have expanded the new design space.

Automotive:

Automotive lightweighting has become the trend of the world's automotive development. The density of aluminum is about 1/3 of that of steel. Aluminum replaces steel to make cars, which can reduce the weight of the entire vehicle by 30% to 40%. The weight of the engine can be reduced by 30%. The aluminum radiator is 20% lighter than the same copper product. 40%, aluminum wheels can reduce weight by about 50%. The lightweight body can greatly improve the speed and handling of the car, and the high-strength aluminum alloy can also bring higher safety performance.

RailTransit:

High-speed rail is a "large user of aluminum", and more than 85% of a high-speed rail car body material is aluminum extrusion. High-speed trains with a speed of over 200 kilometers per hour have high requirements for light weight, tightness, and corrosion resistance, while aluminum alloys have the characteristics of light weight, high strength, corrosion resistance, and strong plasticity, making aluminum profile car bodies absolutely suitable for rail vehicle applications. Advantages, the vehicles currently traveling on high-speed railways in China are basically aluminum profiles.

ships:

Aluminum is an advanced material for the construction of ships and marine engineering structures. The light weight, strong mechanical properties, and corrosion resistance of aluminum alloys make it the material of choice for modern ships. Aluminum alloy vessels have the advantages of high speed, long service life, high deadweight, and low maintenance costs.

aviation:

Structural weight reduction can be described as "Keke calculations" in the aerospace field, and thus the aerospace field has become an important application market for aluminum alloy materials. High-strength aluminum alloys have the advantages of low density, high strength, and good hot workability. The plates, extruded profiles, and hubs made of them have a wide range of applications in aerospace components.
