The development of the aluminum industry. Aluminum is one of the six major metal elements in nature, and China has abundant aluminum resources, exceeding the content of iron by two-thirds. However, the development and utilization of these resources are far behind that of iron resources, mainly due to deficiencies in resource utilization and product development. Currently, China has prioritized aluminum resource development as a key project, particularly in the industrial manufacturing sector. In recent years, the speed of development and application of aluminum profile products in China has accelerated, with continuous improvements in aluminum resource development capabilities and technology. The variety of products has rapidly increased, and the utilization rate of aluminum resources has been continuously enhanced, speeding up the process of aluminum resource development in China.
