Applications of Aluminum extrusion in train construction
aluminum in the railway industry
Aluminum in train construction ; Metal metals are used in industries including the transportation industry. In the transportation industry, it is also less used in some cases where automobiles are used, for example in the transportation industry compared to the air and rail transportation industries. Trains are used in the train manufacturing industry to such an extent that it can be said that they are used in all parts of train construction, especially freight trains.

Advantages of using aluminum in train construction :
The reason for the widespread use of aluminum in the construction of trains is due to the special properties of aluminum, including:
1- Low weight of aluminum: Light weight of aluminum is an important feature in the widespread use of aluminum, because the light weight of aluminum and its use in the structure of the train body reduces the weight of the train, followed by increasing train speed – reducing fuel consumption and ultimately increasing life. It becomes a train.
- High ductility: The ductility property has made it possible for train designers and builders to use aluminum in the construction of trains to convert metal into a desired shape and design, which in itself is the most beautiful structure of the train and at the same time its strength. it helps.
- Recyclability of aluminum: Aluminum has a higher recyclability than other metals, and this property has made the use of aluminum less harmful to the environment.
- Corrosion resistance: Aluminum is corrosion resistant in that when aluminum is exposed to air, a surface protective layer is formed on it and thus is protected from corrosion, which is an important feature of aluminum. Has become a widely used metal in various industries; Also, due to this feature, aluminum is used in the construction of trains, which increases the efficiency and life of the train and reduces the maintenance costs of the train.
- Strength to weight ratio: High strength to low weight ratio is another reason for the widespread use of aluminum in train construction.

History of the use of aluminum in the construction of trains
Before the use of aluminum in the construction of trains, wood and cast iron were used. This trend continued for several years, but due to the high corrosion properties of cast iron, its use was rarely reduced in the construction of trains; then the use of aluminum It was considered in the construction of the train.
Aluminum was first used in the construction of trains in 1894, and later the use of aluminum in the railway industry increased, so that in the 1930s aluminum was used more in the construction of trains, but in the 1940s until many years rarely. Aluminum was used to build the train.
Around the 1940s, aluminum was rarely used in train construction for many years; this trend continued until in 1980, aluminum became the main metal in train construction as the main metal in the rail transport industry; For this reason, it can be said that the use of aluminum in the construction of trains is almost 50 years old.

Application of aluminum in train construction:
Aluminum is composed of various alloys. Aluminum is used in the construction of trains in various parts, and each type of alloy is used for different parts due to its properties. 5000-6000 and 7000 series alloys, including aluminum alloys in train construction can be mentioned.
Aluminum is used in the construction of trains for parts such as the walls of the body of passenger and freight trains, because the use of aluminum in the body reduces the overall weight of the train, in which case the train can carry more cargo; On the other hand, this reduces the fuel consumption of the train.

One of the advantages of using aluminum in train construction is that with the expansion of rail transport and increasing the speed of trains, the use of aircraft for routes that can be traveled by train has been reduced, and this has reduced the entry of greenhouse gases into the Earth’s atmosphere. have given.
