Throughout the history of cars, trucks and other vehicles, aluminum has always been an indispensable material, but it is still surprising to understand how new electric vehicles rely on aluminum alloys. This just shows that even after 100 years, aluminum is still experiencing a huge innovation that is vital to industry.

Overview of electric vehicles

Although gasoline power vehicles have existed for more than a century, commercial sales of electric vehicles, also known as EV, have only developed recently. With the dual threats of climate change and peak oil prices, the more sustainable internal combustion engine (ICE) alternatives have become many research and development themes. Aluminum plays an important role in the transformation.

Battery -driven electric vehicles do not rely on gasoline, but have large, charged battery units to provide energy required for driving cars. Today's electric vehicle mileage ranges from 80 miles to 300 miles, depending on the model, researchers are constantly improving these numbers. Compared with gasoline vehicles, the carbon footprint of electric vehicles in its life cycle is much lower and contributes to a more environmentally friendly earth.

It is estimated that from 2010 to 2019, the number of electric vehicles on the road increased from 17,000 to more than 7 million vehicles.

Is aluminum for electric vehicles?

Like traditional cars, aluminum is also a popular material for modern electric vehicles. Both internal combustion engines and electric vehicle manufacturers need to reduce the weight of the vehicle. Internal combustion engine cars and truck manufacturers are working hard to meet the CAFE (average fuel economy) standard for fuel efficiency, while electric vehicle manufacturers are trying to improve their mileage before charging. The less the required electricity is required, the farther the distance between the vehicle will be driving after the battery is charged.

The advantage of aluminum on electric vehicles is not just weight. Aluminum is better than steel and other metals. This is the key consideration of the highly sensitive electrical component of electric vehicles. Most of the electric cables of electric vehicles also depend on aluminum wires.

Another factor in using aluminum is that it has a more environmentally friendly life cycle, especially when it is easy to recover. Electric vehicles are rated based on the carbon emissions of the entire life cycle, so manufacturers are willing to invest in more sustainable materials such as aluminum.

Tesla has invested a lot of funds in the new aluminum casting technology, allowing them to cast the entire car framework as a single component. The chassis of Tesla Model 3 will be produced by a single -piece framework in the front and rear, and the structural battery box is connected to both. This chassis system includes several parts, which were previously stammered and tightened with welding and other methods; it will eliminate 370 components. The robots required for assembly will also be reduced from about 1,000 to about 300.

The Idra Group of Italy produces 5,500 tons and 6,200 tons of die -casting pressure machines to cast these frameworks. One of the maximum innovations required by these machines is the SHOT system to provide melting aluminum into the mold; it can inject 220 pounds into the cavity in 60-100 milliseconds.

Due to the above reasons, it is estimated that electric vehicles and plug -in hybrid vehicles use 25%more aluminum than traditional cars.

What aluminum alloy is used for electric vehicles?

Generally speaking, aluminum alloy found in traditional cars can also be found in electric cars. The body of electric vehicles is usually made of popular 6XXX series alloys such as 6061, 6016 and 6111. High -resistant corrosion alloys are also common, such as 5182 and 5754. Son and hollow material profiles are also proven to be an indispensable asset in the design and construction of electric vehicles and charging stations. Squeezing is also a popular solution for the application of electric vehicle battery shells.

But in order to further promote the possibility of electric vehicles, new alloys are needed. This is why many of the most advanced electric vehicles, such as Tesla, have adopted a revolutionary new alloy specifically designed for this. For example, the company applied for a patent of a new alloy in 2020 with a yield strength of the alloy A356, but the conductivity was 100.1.

Your sustainable metal partner

Aluminum alloy, due to its continuous progress, has become a durable, adaptability, and high -quality choice for the electric vehicle market. In the case of sustainability and efficiency, it is meaningful to use the most sustainable and cost -effective materials. In terms of reliability and professionalism, cooperation with metal suppliers is also worth it.
