Today, I will introduce the development history of aluminum profiles to you. Aluminum profiles actually appeared very early and are used in all aspects of life. Aluminum profiles have been around since the discovery of aluminum on an industrial level in the 19th century. Aluminum is a metal. The natural form of aluminum is very rare, and it needs to be extracted from ore, and the process is very complicated. Aluminum is difficult to refine, so it is not commonly used in practice. Shortly after it was discovered, the price of aluminum surpassed that of gold. China has amassed a particularly large share of both aluminum production and consumption. The use of aluminum in manufacturing and construction dates back to the Industrial Revolution, when factories began using the material to create various components. Today, aluminum is an essential part of modern life, found in airplanes, automobiles, soft drink cans, construction materials, cooking equipment, guardrails and more. Aluminum is a non-ferrous metal with low density. Aluminum profiles are products born from the transformation of aluminum alloys into shaped objects through an extrusion process. Aluminum alloys typically include copper, magnesium, manganese, silicon, tin, nickel and zinc. These metals are added to improve the mechanical properties of aluminum such as strength, ductility and corrosion resistance. Later, people discovered many types of aluminum alloys one after another. 4XXX series aluminum alloys: At present, my country's automobile pistons mainly use eutectic and hypoeutectic Al-Si alloys; 5XXX series: Al-Mg alloys, especially Al-Mg alloys with high Mg content With high specific strength, good weldability and corrosion resistance, it will become a very competitive material in the fields of aerospace, high-speed trains, and oceans in the future; 6XXX series: it is a key material in the fields of rail transit, automobiles, and electronics; 7XXX series: It has good stress corrosion resistance, is the series with the highest strength among aluminum alloys, and is internationally recognized as the backbone material of aviation. Aluminum extrusions are used in many applications such as window frames, door frames, curtain walls, railings, furniture, solar panels, etc. They are also used to make airplanes and other vehicles. Aluminum profiles have many advantages such as being very durable and can withstand extreme temperatures and weather conditions. They are lightweight yet strong, ideal for larger projects, very resistant to rust, and lightweight for ease of use. Aluminum extrusions are less dense and lighter than other commonly used metals. The density is only 2.70 g/cm³, which is 1/3 of copper or iron. In the production process of aluminum profiles, two processes of cold and hot are used, which have strong corrosion resistance. With good ductility, it can be made of light alloy containing more metal elements, and the material is of high quality.
