3. Alloy aluminum plates/rods/tubes, etc.
Overview ① Aluminum alloy materials. The main alloying elements are magnesium and silicon, which have excellent processing performance, excellent weldability, extrusion and electroplating properties, good corrosion resistance, toughness, easy polishing, color film, and excellent anodizing effect, which are typical Extruded alloy. 3 Aluminum alloy profiles are widely used in building profiles, irrigation pipes, vehicles, benches, and furniture due to their good plasticity, moderate heat treatment strength, good welding performance, and gorgeous surface color after anodizing treatment. , tubes, rods and profiles for lifts, fences, etc.
② It is a low alloyed alloy with high plasticity. It has many valuable features: heat treatment strengthening, high impact toughness, and insensitivity to dispensing. .It has excellent thermoplasticity and can be extruded at high speed into various profiles with complex structures, thin walls, and hollows, or forged into forgings with complex structures. The quenching temperature range is wide and the quenching sensitivity is low. After extrusion and forging, as long as the temperature is higher than the quenching temperature, it can be quenched by water spraying or water penetration. Thin-walled parts () can also be air-quenched. 3. Excellent welding performance and corrosion resistance, no tendency of stress corrosion cracking. Among the aluminum alloys that can be strengthened by heat treatment, the alloy is the only alloy in which no stress corrosion cracking phenomenon has been found. .The surface after processing is very smooth and easy to anodize and color. The disadvantage is that after quenching, if it is parked at room temperature for a period of time, it will have an adverse effect on the strength (parking effect).
Jisheng Company According to the different metal elements contained in the aluminum plates, the aluminum plates can be roughly divided into major categories, that is, they can be divided into series. The following is a step-by-step introduction
1. Series representative series aluminum plates are also called Pure aluminum plate contains the most aluminum among all series. 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 column in conventional industries. Most of the ones currently circulating on the market are the and series. The minimum aluminum content of a series of aluminum plates 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 plates must reach... or above.
The representative series of second series aluminum plates are characterized by high hardness, among which the copper content is the highest, about 3-. The series of aluminum plates are aviation aluminum materials and are currently not commonly used in conventional industries. There are currently few manufacturers producing series aluminum plates in our country. The quality cannot be compared with foreign countries. Currently, imported aluminum plates are mainly provided by Korean and German manufacturers. With the development of my country's aerospace industry, the series of aluminum plate production technologies will be further improved.
The five series represent...3. series. The series aluminum plates belong to the more commonly used alloy aluminum plate 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 other series under the same area. Therefore, it is often used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries. The processing technology is continuous casting and rolling, and it belongs to the hot-rolled aluminum plate series, so it can be used for deep oxidation processing. The aluminum plate series is one of the more mature aluminum plate series in my country.
The six series represents mainly two elements: magnesium and silicon, so it combines the advantages of the series and the series. It is a cold-processed aluminum forged product, suitable for applications that require high corrosion resistance and oxidation resistance. Good workability, excellent interface characteristics, easy coating, and good processability. Can be used on low voltage and aircraft connectors.
General features: excellent interface characteristics, easy coating, high strength, good workability, and strong corrosion resistance.
Typical uses of aluminum: aircraft parts, camera parts, couplers, ship accessories and hardware, electronic accessories and connectors, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, valves and valve parts.
The seven series representatives 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 super-hard aluminum alloy and has good wear resistance. The aluminum plate is stress-relieved and will not deform or warp after processing. All oversized and thick All aluminum plates have been ultrasonically detected to ensure there are no blisters or impurities. The aluminum plates have high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that it is a high-hardness, high-strength aluminum alloy that is often used in manufacturing aircraft structures and futures. It requires high-stress structural parts and mold manufacturing with high strength and strong corrosion resistance. At present, we basically rely on imports, and our country's production technology still needs to be improved.
The eight series are more commonly used and belong to other series. In my memory, the aluminum plate is mainly used for making bottle caps. It is also used in radiators, and most of them are aluminum foil. Not commonly used. Aluminum rod specifications: Maximum diameter: (Imported aluminum rods in stock) Other specifications can be customized for customers.
Another: Our company currently imports a large amount of aluminum plates from Alcoa (Alcoa) in stock, with complete specifications and excellent prices. All manufacturers are welcome to come and purchase
