Aluminum is a very light metal. During the 44 years from 1944 to 1988, the world’s aluminum production has increased by 19 times. The development of aluminum is so fast that aluminum itself has many advantages.聽(also known as aluminum is often producing and living. In The field, generation of steel is replaced by copper and wood, and an important form of aluminum application development is "instead of".

The

In the short-term development of aluminum, demand as has a huge role in promoting, such as the production of aircraft during the World War II to promote the rapid development of aluminum, from 1940 to 1943, the annual output of aluminum increased extremely 230,000 tons to 1.46 million tons, and 1960 Aluminum increased from 4.46 million tons to 10.2 million tons in 1970, which was due to to widespread use of aluminum substitute steel in the construction industry.

The automobile industry is an important pillar industry in the developed countries. A new direction in the current fierce competition in the automobile industry is that the automobile is "lightweight"—"aluminum substitute steel" is an unnecessary trend:

The

1, saving energy. 100kg aluminum can replace steel 200kg, can save 8%; 300kg can save 24%.

The

2, environmental protection, due to the difficulty of recycling of plastic substitute steel, garbage caused by the car has become a disaster, good recycling of aluminum, metal recycling is extremely important, aluminum can be recycled more than 85%.

The

For a period of time in the future, the automotive aluminum industry will become a new direction of development, and technological progress should be accelerated, with new aluminum materials to meet the automotive industry's lightweight needs.
