Common problems in the world aluminium industry

Common problems in the world aluminium industry

1. The recycling system of used aluminium is not perfect

Scrap aluminum recycling methods and technology backward, small-scale recycled aluminum enterprises, low production, only accounting for less than 20% of the original aluminum production, while the industrially developed countries up to 40% or more, on the track of the development of circular economy.

2. Aluminum casting technology and equipment level is not high

Aluminum casting production enterprise scale is not large, production and business scattered, production technology is not advanced, less variety, has not formed a complete casting aluminum alloy system and heat treatment state system, high-quality aluminum alloy castings and die-casting still can not meet the needs of the automotive industry and the rapid development of the national economy.

3. Low concentration of aluminum processing industry

Although the number of aluminium processing enterprises is large, but the concentration of production is low, the scale is small, the low level of repeated construction, the operation is scattered, in addition to a few large enterprises such as Chinalco, has not formed a high level of modernization of large aluminum industry group. After a decade of macro-control and market competition, China's aluminum processing enterprises from the 1990s more than 2,000 reduced to the current 1,400 or so (including more than 780 aluminum extrusion plants, aluminum sheet and foil plant more than 650), but large and medium-sized enterprises less than 20%, and backward small enterprises accounted for more than 80%, the national average capacity of aluminum processing enterprises only 2.5 tons / year or so ( The average capacity of aluminium processing enterprises in the country is only about 2.5 tons/year (the largest capacity is 800,000 tons/year for Southwest Aluminium), while the average capacity of aluminium processing enterprises in industrially developed countries is more than 100,000 tons/year, with the largest capacity reaching 1.7 million tons/year.
