Bicycle Frame Material - The Status and Development Trend of Aluminum Alloy Material

At present, aluminum and aluminum alloy processing industry has entered a brand-new development period, the application of aluminum is more and more extensive, and transportation industry has become the first major user of aluminum. Aluminum is the material of choice for light weight, and is bound to partially replace steel as an important basic material for all sectors of national economy and people's life; aluminum industry is a sunrise industry, and is bound to become one of the important pillar industries of material industry.

The scale and production technology of aluminum and aluminum processing industry at home and abroad have developed rapidly and reached a high level, and a large number of advanced and modernized aluminum group companies have been established, and a large number of new aluminum alloy materials with various properties and functions, different varieties and uses have been developed. Continuously push new, to energy saving, environmental protection and safety, streamlined continuous, efficient, high quality, high-grade direction, developed a large number of large, precise, compact, efficient, energy-saving, multi-functional, fully automatic aluminum and aluminum processing technology and equipment, greatly promote the development of aluminum and aluminum processing industry to the modern direction. At present, China's aluminum industry is also facing a profound change, into a period of unprecedented dramatic differentiation, adjustment, restructuring and development, polarization of enterprises, the process of elimination of winners and losers will be greatly accelerated.

Large-scale, group, scale, modernization and internationalization become one of the important symbols of modern aluminum and aluminum processing enterprises. The industry and products will be adjusted vigorously, the system and mechanism of the enterprise will be innovated continuously, the technological progress will be accelerated, and the management will develop in the direction of modernization, automation, informationization, scientific, efficiency and international integration.

At present, China's aluminum processing industry has entered a new period of development.

From the global level, in recent years, the average annual aluminum demand growth 3 ~ 5%, and can be seen: China is with an average annual growth rate of 15 ~ 25%, which shows that in China's aluminum industry has entered a new period of development.

The new period of economic development has put forward new requirements for energy saving, environmental protection, safety and high efficiency, and aluminum is playing an important role more and more in the new economic period.

(1) aluminum smelting (electrolysis) process is a great energy process, its electricity consumption is 5 times that of steel, much higher than other bulk materials, from this point of view, it is more suitable for the country or region rich in hydropower, to store natural energy.

(2), aluminum is a renewable resource, and its recovery and recycling with very low energy, about 5% of the original energy, renewable energy-saving effect is obvious.

(3), mainly in transportation and building structure, flexibility, light weight, energy saving, high speed these are the real requirements of modern transportation to the application of materials, aluminum is one of the best materials for these comprehensive choices.

(4), the surface affinity of aluminum, the relative simplicity of processing, and the advantages of specific stiffness, specific strength (as well as the ability to absorb energy) make people give more connotation to the safety of aluminum and its fashion characteristics. In addition, aluminum and its alloys play an irreplaceable role in improving the performance of defense equipment, accuracy, rapid response capability and long-range combat.
