Aluminum barcan be used in aviation, aircraft construction, rivet, trailer wheel, the propeller components, metallic building material, forging material, welding material, etc.
ALUMINUM BAR supplierIntroduction
Aluminum (Al) is a kind of light metal, whose compounds are widely distributed in nature. The resources of aluminum in the earth's crust are about 40 to 50 billion tons, ranking the third only after oxygen and silicon.It is the first kind of metal among metal varieties.Aluminum has special chemical and physical characteristics, not only light weight, strong texture, and has good ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance, is an important basic raw material for national economic development.
recycled aluminumis one of the most abundant metallic elements in the world, and its reserves rank the first among metals.It was not until the end of the 19th century that aluminum emerged as a competitive metal for engineering applications and was all the rage.The development of the three important industries of aviation, construction and automobile requires that the material properties have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal -- aluminum.
T3 ALUMINUM BARApplication and classification
According to the different metal elements contained in the aluminum rod, the aluminum rod can be divided into 8 categories, that is, it can be divided into 9 series:
The 1000 series forging ALUMINUM materialrepresents the 1050, 1060 and 1100 series.The 1000 series is the series containing the most aluminum of all the series.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 industries.Most of the 1050 and 1060 series are in circulation.The minimum aluminum content of 1000 series aluminum rod is determined according to the last two Arabic numerals of this series. For example, the last two Arabic numerals of 1050 series are 50.China's aluminum alloy technical standard (gB/ t3880-2006) also clearly stipulates that 1050 contains 99.5% aluminum. Similarly, 1060 series aluminum bar stock factorymust contain 99.6% aluminum.
The 2000 series aluminum rods represent 2A16 (LY16) and 2A02 (LY6).Series 2000 aluminum rod is characterized by high hardness, in which copper element content is the highest, about 3-5%.Series 2000 aluminum rod belongs to aviation forging ALUMINUM material, which is not often used in conventional industry.
It is a typical hard aluminum alloyin aluminum-copper-magnesium series. It is a heat-treatable alloy with high strength, easy to work, easy to turn and general corrosion resistance.
After heat treatment (T3, T4, T351), the mechanical properties of 2024 aluminum rod are significantly improved.Its T3 state parameters are as follows: tensile strength 470MPa, 0.2% yield strength 325MPa, elongation rate: 10%, fatigue strength 105MPa, hardness 120HB.
The 2024 Aluminum baris mainly used for aircraft structures, rivets, truck wheels, propeller assemblies and other structural parts
The 3000 series aluminum rod mainly represents 3003 and 3A21.China's 3000 series aluminum rod production technology is relatively excellent.The 3000 series aluminum rod is mainly composed of manganese.The content is between 1.0 and 1.5, which is a series with good anti-rust function.
The 4000 series aluminum rod represented by 4A01 4000 series belongs to the series with higher silicon content.The typical silicon content is between 4.5 and 6.0%.metallic building material, mechanical parts, forging materials, welding materials;Low melting point, good corrosion resistance, product description: heat resistance, wear resistance characteristics
The 5000 series aluminum rod represents the 5052, 5005, 5083 and 5A05 series.Series 5000 aluminum rod belongs to the more commonly used alloy aluminum rod series, the main element is magnesium, containing between 3-5% magnesium.Also known as aluminum magnesium alloy.The main characteristics are low density, high tensile strength, high elongation.At the same area, the weight of al-mg alloy is lower than that of other series, and it is widely used in conventional industry.The 5000 series aluminum rod is one of the more mature aluminum rod series in China.
The 6000 series aluminum rod represents 6061 ALUMINUM BARand 6063 ALUMINUM BAR, which mainly contain magnesium and silicon, so the advantages of 4000 series and 5000 series are concentrated.Good usability, easy coating, good processing.
The 7000 series aluminum rod represents the 7075 mainly containing zinc.Also belongs to the aviation series, is the aluminum magnesium zinc copper alloy, is the heat-treatable alloy, belongs to the superhard aluminum alloy, has the good wear resistance.
The 8011 of the 8000 series aluminum rods is more commonly used, which belongs to other series.Most of them are used as aluminum foil, and are not commonly used in the production of aluminum rods.
