Xingfa's Aluminium Extruded Products Applied in Metro System

Aluminium alloy is transformed through aluminium extrusion profiles into a remarkable diversity of goods for both the consumer and industrial markets. There are several applications for aluminium extruded products in electronics, automotive, public transit, telecommunications, solar/renewable energy, and other industries.

 

Benefits of Applying Aluminium Extruded Products in Metro System?

Aluminium extruded products were originally used in the aviation industry, which is an important part of the transportation industry. As metro speeds increased, aluminium alloy began to be used in the manufacture of the metro system.

So why do people apply aluminium extruded products in the metro system? Here are some significant reasons:

1. Lightweight

Aluminium extruded products can greatly reduce the net weight of the subway and, at the same time, meet the safety requirements in terms of strength and stiffness. Generally speaking, aluminium body is 30%~50% lighter than steel. Increasing the proportion of aluminium used in the vehicle can effectively make the vehicle lightweight.

2. Excellent Shaping Qualities

Aluminium extruded products are easy to process, manufacture and maintain due to their excellent shaping quality. Subway vehicle manufacturing technology is becoming mature as aluminum welding technology has been improving.

3. High Strength

Commonly, aluminium has typical tensile strength between 40 MPa to 700 MPa. This means subways made of aluminium extrusion profiles can meet the safety requirements in the aspect of strength and rigidity.

4. Corrosion Resistance

Aluminium extrusion profiles are corrosion-resistant. A dense oxide film is easily formed on the surface of aluminium extruded products, which has good oxidation resistance in the atmosphere. Therefore, the corrosion resistance of aluminum alloy car body is better than that of steel, especially on the components that are not easy to be painted, such as the box structure and some beams and columns inside, the advantages of aluminum counterparts are obvious.

5. Recyclable

Last but not least, aluminium extruded products are 1000% recyclable, and during the recycling process, they retain all of the original properties. Therefore, it is more cost-effective to use recycled metal than prime metal during production.

Xingfa Aluminium Extruded Profiles for Metro

Although structural aluminium extrusion applications can be more expensive than other options, such as steel tubes, they can be produced more quickly and are ultimately more affordable because labor expenses are reduced, which is why we recommend aluminium extruded profiles for the metro system.

 

The finished item of Xingfas aluminium profiles for metro can be utilized independently or quickly linked with another metal component. And they dont corrode since it has a surface oxide coating on them naturally. It is also a perfect conductor of heat and electricity and can withstand high temperatures without emitting poisonous gases. There are various surface finishing of this aluminium extruded profiles for you to choose from. For example, mill finished, anodizing, electrophoresis, powder coating, PVDF, wood finish, etc.

 

Aluminiums structural integrity is quite tough while being light, though not on the same level as case-hardened steel, which is why it is used in aircraft and construction applications. Different aluminium extrusion alloys have varied qualities and advantages. Therefore its important to investigate several alloy kinds to determine which one is appropriate for a project.
