ALUMINUM EXTRUSION

Aluminum processing, using plastic processing methods to process aluminum ingots into materials, mainly including rolling, extrusion, stretching, and forging. Aluminum processing began to be produced in an industrial manner in the early 20th century. Before the 1930s, copper processing production equipment was basically used, and the products were mainly used in aircraft manufacturing. After the 1960s, aluminum production developed rapidly, with an annual growth rate of approximately 4-8%. Products were widely used in sectors such as aviation, construction, transportation, electrical, chemical, packaging, and daily necessities industry. The production is second only to steel, ranking second in metal materials. In the mid-1950s, China built a relatively large aluminum processing plant, forming a production system. The products have been serialized and there are seven alloy series, which can produce eight types of products: plate, strip, foil, pipe, bar, profile, wire, and forging (free forging, die forging).
