Supply Dongguan precision aluminum rods, metal manufacturers wholesale

Aluminum rod is a kind of aluminum product. The melting and casting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process. According to the different metal elements contained in aluminum rods, aluminum rods can be roughly divided into major categories, that is, they can be divided into series:
1. Series aluminum rods represent,, series. Among all series, the series has the highest aluminum content. The purity can reach above. Since it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industries. Most of the ones circulating on the market are and series. The minimum aluminum content of a series of aluminum rods is determined based on the last two Arabic numerals of the series. For example, the last two Arabic numerals of the series are. According to the international brand naming principles, the aluminum content must reach. The above is a qualified product. Our country's aluminum alloy technical standards (B/3-) also clearly stipulate that the aluminum content reaches... In the same way, the aluminum content of series aluminum rods must reach... or above.
2. Representative series of aluminum rods. The series of aluminum rods are characterized by high hardness, among which the copper element content is the highest, about 3-. The series of aluminum rods are aviation aluminum materials and are not commonly used in conventional industries.
It is a typical hard aluminum alloy in the aluminum-copper-magnesium system. It is a heat-treatable alloy with high strength, easy processing, easy turning, and average corrosion resistance.
After the aluminum rod is heat treated (33), the mechanical properties are significantly improved. Its 3-state parameters are as follows: tensile strength, yield strength 3, elongation:, fatigue strength, hardness B.
The main uses of aluminum rods: aircraft structures, rivets, truck wheels, propeller components and other structural parts
3. 3 series aluminum rods represent and mainly. my country's 3 series aluminum rod production technology is relatively excellent. Series 3 aluminum rods are made of manganese as the main component. The content is between. It is a series with better anti-rust function.
4. The series of aluminum rods represented by series Aluminum rods belong to the series with higher silicon content. Usually the silicon content is between. It belongs to construction materials, mechanical parts, forging materials, and welding materials with low melting point and good corrosion resistance. Product description has the characteristics of heat resistance and wear resistance
5. Series aluminum rods represent,, series. The series aluminum rods belong to the more commonly used alloy aluminum rod series. The main element is magnesium, and the magnesium content is between 3-3. It can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than that of other series under the same area, and it is also widely used in conventional industries. This series of aluminum rods is one of the more mature aluminum rod series in my country.
6. The representative of series aluminum rods, 3, mainly contains two elements: magnesium and silicon, so it combines the advantages of series and series. It is a cold-processed aluminum forged product, suitable for applications that require high corrosion resistance and oxidation resistance. Good workability, easy coating and good processability.
7. Representative series of aluminum rods mainly contain zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy. It is a heat-treatable alloy. It is a superhard aluminum alloy and has good wear resistance. It basically relies on imports, and my country's production technology needs to be improved.
8. The most commonly used series of aluminum rods belong to other series. Most of them are used in aluminum foil. They are less commonly used in the production of aluminum rods.
