Process of Aluminum Extrusion in Steps | Advantages of Aluminum Extrusion Process

1) In the aluminum extrusion process, the extruded metal can obtain a more intense and uniform three-dimensional compressive stress state in the deformation zone than rolling and forging, which can give full play to the plasticity of the processed metal itself. Therefore, the extrusion method can be used to process those low plastic and difficult deformation metals or alloys that are difficult or even impossible to be processed by rolling or forging. At present, extrusion is still the most superior method to produce products directly from ingots.

2) Aluminum extrusion can not only produce pipe, bar, profile, and line products with simple section shape but also produce s materials and pipes with variable section and extremely complex shape, such as stage variable section profile, gradually variable section profile, integral wall panel profile with special-shaped stiffener, extremely complex hollow profile, variable section pipe, porous pipe, etc.

3) Aluminum extrusion process is very flexible. Products with different shapes, specifications, and varieties can be produced on one piece of equipment only by replacing extrusion tools such as molds. The replacement of extrusion tools is simple and easy to operate, time-consuming, and high efficiency. This processing method is most economical and applicable to aluminum alloy material processing plants with small order batches and many varieties and specifications.

4) The taper of extruded products is higher than that of hot rolled and forged products, and the surface quality of products is also better. With the improvement of process level and die quality, we can produce ultra-thin, ultra-high precision and high-quality profiles. This not only greatly reduces the total workload and simplifies subsequent processes, but also improves the comprehensive utilization rate and yield of extruded materials.

5) For some aluminum alloys with extrusion effect, the longitudinal strength of extruded products after quenching and aging is much higher than that of similar products processed by other methods. This is of practical value for excavating the strength of aluminum alloy materials and meeting special application requirements.

6) The process is short and the production is convenient. The overall structural parts with a larger area than those by hot die forging or forming rolling can be obtained by one extrusion, and the equipment investment is less, the die cost is low and the economic benefit is high.

7) Aluminum alloy has good extrusion characteristics and can be processed through a variety of extrusion processes and a variety of die structures. In recent years, the production of complex hollow aluminum products by welding and extrusion has been widely used and popularized.
