Application and development prospect of aluminum block in the future
Aluminum processing refers to the plastic processing method to process aluminum ingots into materials. The main methods include rolling, extrusion, stretching and forging.
Processed products are mainly divided into the following three categories: primary products, products directly cast from primary aluminum, without pressure processing, such as high pure aluminum, aluminum powder, rolled flat ingot, cast-rolled strip blank for rolling, wire rod for drawing, extruded round ingot, forged ingot blank, etc.
The structural characteristics of China's aluminum consumption determine the structural defects of products. During the 12th Five-Year Plan period, the proportion of extruded materials in China accounted for about 60% of the processed materials, the application ratio of aluminum profile and plate and strip in foreign developed countries is 2: 3, while this ratio in China is relatively low at present. China has the largest aluminum processing scale in the world, but the homogenization of products is serious and the technological innovation strength is relatively weak, at present, high-end aluminum strips and foil products such as aviation-grade aluminum thick plates, aluminum strips for automobile bodies, and high-voltage anode electronic foils are mostly imported.
According to the calculation of aluminum alloy for a single aircraft and the total number of aircraft, the demand for aluminum for Chinese civil aircraft manufacturing in 2018 was 2.
About 50 thousand tons, will reach the level of about 100 thousand tons in 2025, and the compound annual growth rate from 2016 to 2025 will reach 25%, which is higher than the demand for aluminum materials in any industry, especially high-performance alloy materials.
