The lightweight of automobiles has become a trend in the development of automobiles worldwide.

The density of aluminum is about one-third of that of steel. Replacing steel with aluminum in manufacturing cars can reduce the weight of the entire vehicle by 30% to 40%, manufacturing engines can reduce weight by 30%, aluminum radiators are 20% to 40% lighter than the same copper products, and aluminum wheels can reduce weight by about 50%.

The lightweight body of the car can greatly improve its speed and handling ability, and high-strength aluminum alloy can also bring higher safety performance.
