Aluminum rod is a kind of aluminum product. The casting process of aluminum rod includes melting, purification, impurity removal, gas removal, slag removal and casting process. According to the metal elements contained in aluminum rods, they can be roughly divided into eight categories.
aluminum
Aluminum (Al) is a light metal, and its compounds are extremely widely distributed in nature. The resources of aluminum in the earth's crust are about 40 to 50 billion tons, ranking third only to oxygen and silicon. In metal varieties for the first category of metal. Aluminum has special chemical and physical characteristics. It is not only light in weight and strong in texture, but also has good ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance. It is an important basic raw material for national economic development.
Aluminum is the most abundant metal element on earth, and its reserves are the first in metals. It was not until the late 19th century that aluminum emerged as a competitive metal for engineering applications and became fashionable. The development of aviation, construction and automobile requires the unique properties of aluminum and its alloys, which is greatly conducive to the production and application of this new metal -- aluminum.
Product categories
According to the metal elements contained in aluminum rods, they can be roughly divided into eight categories
I. 1000 series aluminum rod represents 1050, 1060, 1100 series. In all series 1000 series belongs to a series with the most aluminum content. The purity can reach above 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in conventional industry at present. Most of the 1050 and 1060 series are in circulation. 1000 series aluminum bar according to the last two Arabic numbers to determine the minimum aluminum content of this series, such as 1050 series last two Arabic numbers for 50, according to the international brand naming principle, aluminum content must reach 99.5% or more for qualified products. China's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. In the same way, 1060 series aluminum bars must contain more than 99.6% aluminum.
2. 2000 series aluminum rod represents 2A16 (LY16), 2A02 (LY6). 2000 series aluminum bar is characterized by high hardness, with the highest content of copper element, about 3-5%. 2000 series aluminum rod belongs to aviation aluminum material, which is seldom used in conventional industry.
2024 is a typical duralumin alloy in the aluminum-copper-magnesium system. It is a heat-treatable alloy with high strength, easy to work, easy to turn, and moderate corrosion resistance.
After heat treatment (T3, T4, T351), the mechanical properties of 2024 aluminum bar are significantly improved. Its T3 state parameters are as follows: tensile strength 470MPa, 0.2% yield strength 325MPa, elongation 10%, fatigue strength 105MPa, hardness 120HB.
Main applications: aircraft structure, rivets, truck wheels, propeller components and other structural parts
3. 3000 series aluminum bars mainly represent 3003 and 3A21. Our country 3000 series aluminum rod production technology is relatively excellent. 3000 series aluminum bars are made of manganese. Content between 1.0-1.5, is a good rust - proof series.
4. 4000 series aluminum rod represents 4A01 4000 series aluminum rod belongs to the series with high silicon content. Usually the silicon content is between 4.5-6.0%. Construction materials, mechanical parts, forging materials, welding materials; Low melting point, good corrosion resistance, heat resistance and wear resistance
5. 5000 series aluminum rod represents 5052, 5005, 5083, 5A05 series. 5000 series aluminum rod belongs to the more commonly used alloy aluminum rod series, the main element is magnesium, magnesium content between 3-5%. It can also be called aluminum magnesium alloy. The main characteristics are low density, high tensile strength, high elongation. Under the same area, the weight of al-mg alloy is lower than other series, and it is widely used in conventional industry. In our country 5000 series aluminum rod belongs to one of the more mature aluminum rod series.
6. 6061 is a cold processed aluminum forging product, suitable for corrosion resistance, high oxidation requirements of the application. Good usability, easy coating, good processability.
7. 7000 series aluminum rod represents 7075 mainly contains zinc element. Also belongs to aviation series, is aluminum magnesium zinc copper alloy, is heat treatment alloy, belongs to super hard aluminum alloy, has good wear resistance. Depend on import basically, our country's production technology still needs to improve.
8. 8000 series of aluminum rod is more commonly used for 8011 belongs to other series, most of the application is aluminum foil, aluminum rod production is not commonly used.
According to the shape can be divided into: round aluminum bar, square aluminum bar, hexagonal aluminum bar, trapezoidal aluminum bar.
