The transportation industry is an inevitable part of life and one of the important factors to improve the quality of life and the quality of life. The current transportation industry mainly includes airplanes, trains, high-speed rail, subways, cars, trucks, motorcycles and bicycles, and ships. Transportation aluminum profiles
are required for support in these transportation tools. Let's analyze: the development and application of transportation aluminum profiles in railway, automobile, motorcycle and bicycle and shipbuilding industry.
In today's era, high speed, energy saving, safety, comfort and environmental protection are important issues in the transportation industry, and lightweight is the most effective way to achieve the above goals. After years of comparative research, the use of transportation aluminum profiles to make transportation tools, especially high-speed modern vehicles and ships, is more scientific, advanced and economical than wood, plastic, composite materials, weathering steel and stainless steel. Therefore, the application of transportation aluminum profiles in the transportation industry is gradually gaining popularity.
In industrially developed countries, the amount of transportation aluminum profiles used in the transportation industry accounts for about 30% of the total consumption of aluminum, of which the amount of transportation aluminum profiles used in automobiles accounts for about 15%. Mainly used in the manufacture of car body structural parts, doors and windows and shelves, engine parts, cylinder blocks, cylinder heads, air conditioners, radiators, body panels, skin panels and hubs, as well as various passenger ships, fishing vessels and various business vessels, the superstructure of special ships, mounting panels, bulkheads, skin panels, engine parts, etc. At present, some industrially developed countries have developed all-aluminum automobiles, all-aluminum motorcycles, bicycles, all-aluminum speedboats and racing boats, all-aluminum high-speed passenger car boxes and subway vehicles, and the transportation industry has become the largest user of aluminum profiles.
