China Secondary Aluminum Market Analysis
Li
Hongwei, Sigma Group 2011-05


Secondary aluminum includes secondary cast aluminum and secondary wrought aluminum, and we will focus on secondary cast aluminum since secondary wrought aluminum has not developed into a separate industry. Generally speaking, the growth of secondary aluminum demand slows, but industrial competition intensifies. China’s secondary aluminum industry is entering an important turning period. 1. Overview of China Secondary Aluminum Industry 2. Analysis of Secondary Aluminum Demand and Competition 3. Development Trend of Secondary Aluminum Industry

。
Technical Management China's secondary aluminum industry is mixed, and large enterprises are mainly in mechanized operations, while small and medium enterprises are mainly in manual-based operations. There are world-renowned modern enterprises and a large number of small-scale family-owned enterprises with low technology in China. Operation Mode China’s secondary aluminum industry is diversified, and some enterprises mainly produce products used for automobile production, and the quality of their products is stable, and prices are high, while other enterprises mainly produce products for production of household appliance and motorcycle, and low cost and low price are a powerful mean of survival for those enterprises.

Distribution of China’s Secondary Aluminum Industry

China’s secondary aluminum enterprises are mainly foreign-funded and private-owned. China’s scrap aluminum recycling and circulation are mainly in two areas. First, the eastern coastal area, such as the Yangtze River Delta, Pearl River Delta, Bohai Bay. Second, the inland cities, such Chongqing, Fengcheng in Jiangxi province, Changge in Henan province, Miluo in Hunan province.
Huge Gap of Environmental Protection and Technical Facilities in China’s Secondary Aluminum Industry
Most secondary aluminum enterprises are manual-based and family-managed, with poor working conditions are poor, and the secondary aluminum industry is a typical labor-intensive industry, with low application of advanced equipment and production technology, less capability of industrial supporting, incomplete environmental protection facilities. Those enterprises only own small reverberatory furnace and other simple equipments, and it is difficult for them to adapt to the requirements of large-scale industrialization.

Overview of China’s Secondary Aluminum Industry
Enterprise Scale The scale of secondary aluminum enterprises in China kept increasing, and there are at least six enterprises with annual output exceeding 100 kt at present, and there was only one such enterprise five years ago. The total number of enterprises are still 1,000 or so. There are at least five secondary aluminum projects with capacity greater than 100 kt/yr under construction, and the higher level of scale laid the foundation for the technical progress and industrial upgrading of secondary aluminum industry.
The Sigma Group built large-scale plants in Shanghai, Zhangzhou and Chongqing, with the leading technology level in the industry, and their production model is changing from mechanization to automation.

Forecast of China’s Output of Cast Aluminum Alloy

China’s secondary aluminum capacity is a mystery, and we can not get the exact data because of underground economy. However, China’s output of secondary aluminum is approximately 3.5 million mt based on comprehensive assessment and estimation of production and imports of scrap aluminum, as well as end consumption from domestic aluminum die-casting enterprises.
