Aluminum extrusion profile is made by placing activated coatings in a solution of salt and hydrochloric acid for chemical treatment. Aluminium profile is often chosen for their excellent electrical conductivity. Under the same mass, the electrical conductivity of aluminium is nearly twice that of copper, and its thermal conductivity is about 50-60% of copper's, which is beneficial for manufacturing aluminium heatsink profile, evaporators, heating appliances, cooking utensils, and automotive cylinder heads.      Aluminium profiles are non-ferromagnetic, which is an important characteristic for the electrical and electronics industries. Additionally, they cannot self-ignite, making them crucial for applications involving handling or contact with flammable and explosive materials. Aluminum profiles also have a very high recyclability rate, with recycled aluminum having properties almost identical to those of virgin aluminum.      During production, aluminum rods are transported to the assembly line and heated at high temperatures. The rods are then cut into smaller segments by a cutting machine. These small segments are directly fed into an extrusion press, where a hydraulic pump forces the aluminum rod through a die head to form elongated aluminum profiles.. If different specifications of aluminum profiles are needed, different die heads must be swapped in advance. The die head directly determines the shape of the extruded aluminum profile and also has a certain flow-blocking effect.      Therefore, aluminum profiles of a certain shape must be cut into equal lengths by a cutting machine for easy transportation. The cut aluminum profiles then undergo another stretching process, and any deformed parts are removed during this process, known as irregular cutting. At this point, the extruded aluminum profiles are basically formed.They are then placed in a aging hardening furnace for aging treatment before becoming finished products.

     Aluminum extrusion profile is widely used in various fields such as industry, machinery, and aerospace because they have the following advantages. Aluminium profiles are smaller than other commonly used metal molds, lighter in weight, with a density of only 2.7 grams per cubic centimeter, which is one-third that of copper and iron. During use, there is no need to consider its required load-bearing capacity. Secondly, during the production process of aluminum profiles, both hot and cold processes are used, resulting in strong corrosion resistance. One of the major requirements for outdoor aluminium profiles window and door  is their corrosion resistance.      Aluminium profile has excellent ductility and can be alloyed with many metallic elements. This high-quality material has strong plasticity compared to other metal materials, offering significant advantages in manufacturing. Along with these characteristics, aluminum profiles have good casting properties, allowing them to be processed into different shapes. After surface treatment, the appearance of aluminum profiles is bright and colorful, making them very decorative. Aluminum has stable chemical properties, is non-magnetic, and can be recycled repeatedly, making it a benign recyclable metal material.      In addition, aluminium profile has a small elasticity coefficient, do not produce sparks upon collision, perform best in automotive technology, and have excellent thermal and electrical conductivity, standing out in short-distance power transmission. Compared to other metal materials, aluminum does not cause metal pollution or toxicity, and its surface oxide layer does not contain volatile metals. These features make it an important raw material, with its application scope becoming increasingly broad as society develops.
