Cans promote the development of aluminum plate production for cans
Although Chinas cans market is still in an oversupply situation due to the lack of standardization in the market, compared with developed countries, Chinas per capita consumption of cans is still very low, averaging only 4 cans per person per year, while the United States has reached 380 cans per person. This shows that with the enhancement of our countrys overall national strength and the improvement of peoples living standards, as well as the rise of a new round of high tide of aluminum processing investment, this situation will soon be reversed, and there is still broad room for the development of the aluminum cans market. The increase in demand for cans is also bound to promote the development of aluminum plate production for cans. In the next few years, the demand for aluminum for cans in our country will continue to increase. With the progress of cans production technology and aluminum processing technology and the intensification of market competition, reducing material cost and improving material performance are the eternal goals pursued by the development of cans production technology. The international community has begun to study the integrated alloy of tank body, cap and pull ring in order to further improve the recycling rate of materials, reduce costs and improve environmental protection benefits. In terms of processing methods, developed countries have begun to use continuous casting and rolling technology to produce aluminum alloy materials for cans, further reducing processing costs.


Due to backward production technology and equipment, 95 % of Chinas aluminum for cans has been dependent on imports, which costs a lot of foreign exchange every year. From 1991 to 1996, China imported 347,800 tons, of which 100,000 tons in 1995 and 120,000 tons in 1996, with an average annual growth rate of 30.5 %. In 1999, the consumption of materials for making cans nationwide was 145,000 tons, with the exception of about 8,800 tons provided by the southwest aluminum processing factory, the rest of which were all imported. In recent years, Chinas can-making industry has developed rapidly, and the demand for aluminum for cans has also increased continuously. it is estimated that the consumption of aluminum for cans in China will reach 215,000 tons in 2005. Experts pointed out that with the continuous improvement of production technology, light weight and the improvement of forming speed, cans have put forward stricter requirements on the performance of aluminum alloy sheets. Only by effectively controlling every link in the whole production process of aluminum plates and continuously improving the inherent metallurgical quality and performance of aluminum plates can aluminum plate and strip production enterprises adapt to the production needs of cans.
