Aluminum alloy is made of pure aluminum by adding some alloying elements, such as aluminum-manganese alloy, aluminum-copper alloy, aluminum-copper-magnesium hard aluminum alloy, and aluminum-zinc-magnesium-copper super-hard aluminum alloy. Aluminum alloy has better physical and mechanical properties than pure aluminum: easy processing, high durability, wide application range, good decorative effect, and rich color.
Aluminum alloy is the most widely used non-ferrous metal structural material in the industry, and it has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. Aluminum alloys are divided into rust-proof aluminum, duralumin, super-duralumin and other types. Each type has its own range of use and has its own code for users to choose from.
Basic knowledge about aluminum alloy
"Alloys" are mixtures of different metal elements, usually created to enhance the strength and durability of materials. Aluminum alloys usually consist of the latter as the main metal in the mixture, depending on the desired application, and are usually combined with other elements (such as silicon, tin, manganese, and even copper, tin, and magnesium). With the right combination of elements, aluminum can achieve higher strength, and in some cases, aluminum may even outperform steel. The alloy has the same advantages as pure aluminum, and because of its lower melting point, it is also cost-effective.
An alloy based on aluminum with many other alloying elements is one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloys also have specific characteristics of alloys due to the different types and quantities of added alloying elements. The density of aluminum alloy is 2.63～2.85g/cm, high strength (σb is 110～650MPa), specific strength is close to high alloy steel; specific stiffness is higher than steel, good casting performance and plastic processing performance, good electrical conductivity, Thermal conductivity, good corrosion resistance and weldability, can be used as structural materials, and has a wide range of applications in aerospace, aviation, transportation, construction, electromechanical, light and daily necessities.
