Aluminum Alloy - Prospective Trend For Automobile Manufacturing

BlogDate: 07-09-2023 by: Ngan Le

Exhaust fumes from factories and vehicles have increased global environmental pollution. The application of aluminum alloys in manufacturing industries, specifically the automobile industry, has significantly reduced fuel consumption. Therefore, the manufacturers can control the amount of smoke emitted from the factory, contributing to the future development of green production trends for the automotive industry.

Learn about aluminum alloys in automobile manufacturing

In today's automotive industry, aluminum alloy has begun to appear and is seen as a green solution to replace the defects in previous automobile manufacturing. Aluminum is vital, not inferior to steel, and aluminum is much lighter than steel.

The primary aluminum alloys used to manufacture cars include 1100, 2024, 3003, 3004, 3105, 4032, 5005, 5052, 5083, 5182, 5251, 5754, 6016, 6061, 6181, 7003, and 7046. Aluminum alloys are commonly used in the automotive industry, including aluminum of the 6000 system; aluminum of the 7000 system is also preferred in many cases.

Each type of aluminum alloy has its characteristics and symbolic numbers that classify the chemical element associated with aluminum. Alloys in the 5xxx system will be a reaction between aluminum and magnesium, similar to the 6xxx alloy will be a combination of aluminum, magnesium, and silicon, and finally, the 7xxx type includes aluminum, zinc, and magnesium.


Automotive aluminum alloy applications

In the past, aluminum alloys were used rarely in automobile manufacturing. Mainly, aluminum made some small parts of the car structure. However, the popularity of aluminum alloys is becoming more widespread because aluminum's durability has been gradually appreciated through production activities.

Aluminum is the first choice in chassis cars: many manufacturers are now taking advantage of aluminum's lightweight to produce frames and replace iron in the past. Being constituted by aluminum alloy on the chassis has dramatically improved the vehicle's performance while ensuring the durability of the vehicle.

Car interior: Aluminum is also a bright and glossy material, so choosing aluminum alloy for a car interior will bring a high aesthetic when interiors are always in new and glossy condition.

Since 2014, a series of cars with 100% all-aluminum constitution has been seen. Many car manufacturers have used aluminum alloy to produce the entire chassis structure with many different aerodynamic shapes. Famous car manufacturers participating in this list, mentioned as Ford, BMW, and Mercedes... have quickly joined this trend.


Some advantages of aluminum alloy

Support the car to accelerate and break the speed

Aluminum is proven to be 40% lighter than steel, so every kilogram of aluminum alloy is equivalent to a weight loss of 1kg for cars created with traditional steel back in the day. The vehicle's weight significantly supports the vehicle in breaking through speed, and the braking distance will become shorter, providing high safety when driving.

Reduce waste emissions

Aluminum is considered a material that creates less waste than other materials because investing in the production of aluminum alloys for cars will help businesses save a lot of money in disposing of waste.

Aluminum is also a recyclable material that can be recycled continuously without changing its internal properties. When a vehicle has reached the end of its useful life, the aluminum material manufactured in the car can still be reused for other purposes.

Outstanding corrosion resistance and durability

Aluminum alloy is essentially a combination of aluminum and additional elements, including manganese and silicon. This is considered an excellent anti-corrosion chemical reaction when it has the effect of diffusing oxidizing agents. As a result, cars made of aluminum alloy possess remarkable heat-resistant and anti-corrosion properties, thus extending the vehicle's life cycle.


Enhance safety

Aluminum alloy is beneficial for cars with high power as it absorbs shock very well. Thanks to this great advantage, manufacturers can design concentrated force absorption positions on the car's body to avoid the situation where all the force will be concentrated on the driver.

In addition, aluminum is also helpful for impact resistance to other parts of the vehicle thanks to its good force absorption. This contributes to increasing the vehicle's safety in the collision case while other parts of the vehicle remain in their original shape.

The increasing demand for cars has led many businesses to wonder how to increase vehicle production while saving costs. Aluminum alloy is the correct answer to that question. Experts confirm that car manufacturers will gradually use aluminum alloys in their models in the next ten years.
