In recent years, a kind of "aluminium bottle and cans" product which can be opened by screw and sealed repeatedly has become the frontier product in the field of global metal packaging, and the development of this kind of bottle and cans material has also become the focus of attention of aluminium processing factories. Nanshan Light Alloy Company is keen to capture this frontier market information, market-oriented, through the unremitting efforts of R&D personnel, and ultimately successfully developed and put into production aluminium sheet and strip products for aluminium bottles and cans. This not only breaks the monopoly of foreign patented technology, but also promotes the development of domestic bottles and cans to the world's high-end market.

Compared with traditional cans, the advantages of "aluminium bottles and cans" mainly include easy opening, multiple sealing, exquisite appearance, etc. They are more in line with the development direction of customer differentiation and high-end, cater to the younger and fashionable consumption culture, and are more and more widely used in the high-end and emerging fields of traditional beverages. With the production of several bottle and canned material production lines in China in the past two years, Nanshan Light Alloy has become the first aluminum strip enterprise in the research and development of bottle and canned material in China, relying on its status as a leading domestic enterprise of conventional canned materials and international supply experience.

According to the engineer of Technical Development Department, the necking ratio of bottle and tank material is higher than that of ordinary tank material, which requires high formability and anisotropy of tank material. Both elongation and strength should be guaranteed. If the strength is too low, scratches may occur and stretches may occur during necking. If the strength is too high, it is easy to crack when turning over, which is a few difficult problems encountered in research and development.

Facing the difficulties encountered in product development, the scientific researchers of Nanshan Light Alloy Company did not shrink back. They worked together to study the composition control, soaking system, heat treatment process and material anisotropy of Melt-cast alloys. They carried out many communications, repeated experiments and a series of technical research topics. A variety of technological schemes for different caliber bottles and cans were designed, and then trial-produced strictly according to the schemes, and the internal structure and properties of the products were tested and analyzed. The technological schemes were continuously improved. Finally, the product development of various bottles and cans was completed and industrialized promotion was carried out.

This time, the successful development and promotion of bottle and tank material technology has further expanded the application of aluminium. At present, many kinds of caliber bottle and tank materials produced by light alloy company at home and abroad have realized the conventional batch supply. Earlier this year, this research and development achievement was awarded the Group Science and Technology Progress Award, and its product category was awarded the first prize of science and technology in China's non-ferrous metal industry. At the same time, Nanshan Light Alloy has become the main grass-roots unit of the national standard of canning materials, further grasping the voice of the industry.

According to the Minister of Technology Development of Nanshan Light Alloy Company, this self-developed aluminium alloy strip for aluminium bottles and cans breaks the barriers of patent protection in Japan, the United States and other countries, increases the diversity of products and processes of the company, realizes the independent supply of domestic bottles and cans, and occupies a leading position in the domestic market. At the same time, taking advantage of the global supply advantage of Nanshan, keeping up with the latest development technology of international bottles and cans, seizing the emerging international bottle and cans market, and to a certain extent, promoting the development of domestic bottles and cans to the world's high-end market.

Nanshan Light Alloy Co., Ltd. continuously increases investment in scientific research and innovation, devotes itself to R&D and market development of high-value-added products, improves the technological content of products, realizes a virtuous circle of economic and technological development, and promotes high-quality development of the company by technological innovation in an all-round way.
