The feature of aluminum processing technology in China is that it is advanced and backward at the same time. China's technology and equipment have entered the international advanced ranks, while the technology and equipment of the majority of small and medium-sized enterprises are still at the level of the 1970s-1990s. Thus, the current situation of large but not strong, small but not refined aluminum processing industry in China is formed, which makes the national economy and modern science still rely on the passive situation of foreign imports for some high, refined and pointed aluminum materials.
