Energy effiency is the today’s consumer demand. And aluminum can play an important role in driving this change.
In August 2012, the U.S. government set higher Corporate Average Fuel Economy (CAFE) standards, mandating an average fuel economy of 54.5 miles per gallon for the 2025 model year. Because the use of aluminum provides significant weight reductions for automakers, many car companies are now moving to aluminum to achieve these goals. In fact, in 2009, aluminum’s use in road vehicles offset more than 90 percent of all greenhouse gas emissions associated with aluminum production in North America.
And this is why the aluminum alloy parts are used more and more widely in the world.The automotive industry is moving towards expanding the application of light-weight aluminum alloy castings for various components that previously made from steels or cast irons, for example, more than 50% of new cars in North America are now equipped with aluminum alloy wheels.
