Uses of High-end Aluminum Alloys

1. Uses of High-end Aluminum Alloys Abstract: Aluminum alloy itself features light weight, good corrosion resistance and good barrier performance. With different coatings, forms and thickness, it has a better whole comprehensive properties. Some popular types are aluminum flashing roll, marine aluminum sheet, battery aluminum foil and color coated aluminum strip. Aluminum flashing roll Aluminum flashing coil is a kind of material with certain anti-corrosion function which is mainly used in some construction industries to ensure the thermal insulation of the building and some of its waterproofness to a certain extent. There are many types of aluminium flashing like roof, wall, sill, channel, through wall, cap,etc. The introduction of aluminum flashing decreases water penetration at obstacles such as chimneys, vent pipes, walls,etc., thus making buildings more durable and reducing indoor mold problems. It also belongs to aluminum trim coil. The surface of the material uses metal aluminum foil as the surface layer, so it has the characteristics of moisture resistance, air tightness, heat insulation, resistance to solar ultraviolet light, and abrasion resistance. The aluminum flashing roll is generally composed of three parts, namely self-adhesive layer, middle layer and waterproof surface layer. Its thickness is about 1.5mm and the main raw materials are butyl rubber, polyester cloth, metal aluminum foil, etc. Among these raw materials, butyl rubber is mainly used for the self-adhesive layer, which can enhance the adhesion of the aluminum foil. Since the area covered by the aluminum flashing roll is mostly uneven, so polyester fiberglass cloth is specially added in the middle of the aluminum coil, which can effectively ensure that the

2. material is not easily deformed, and at the same time, it is resistant to high temperature and has a super waterproof function. In addition, the use of aluminum foil as the surface of the aluminum flashing coil greatly increases the physical properties of the coil. It can be used safely between 80°C and -30°C without falling off. Moreover, the metal aluminum foil has high ductility, thin surface layer, strong sealing and corrosion resistance. At the same time, the ignition point of aluminum foil is high, so there is no need to worry about the fire problem. The common specification of aluminum flashing is .019 aluminum coil, preferably .022 to .024-in. 24-inch aluminum flashing roll is also a popular choice. Marine Grade Aluminum Alloys The main marine aluminum includes 5083, 5086, 5383, 5059,etc. 5083 alloy is the commonest aluminum for shipbuilding, 5383 is a higher grade, of which its strength is 1.3 times that of 5083. 5086 aluminum alloy is very popular in European countries. 5059 aluminum is a top grade marine aluminum sheet. 5052 aluminum sheet is mainly for inland freshwater ships. All these marine grade aluminum sheets are in a thickness range of 3-50mm, which are often used to make luxury aluminum alloy yachts, sightseeing boats, fishing boats, assault boats, patrol boats. The current conventional size is 2000mm width and 6000/8000/9000/12000mm length. 5083 aluminum sheet is an importnt 5 series aluminum plate. Because of its high strength, strong corrosion resistance, easy processing and welding, it is mostly used in shipbuilding. In 2012, Austal US built the first batch of "Vigilant" all-aluminum catamaran high-speed transport ships, using 5083 aluminum alloy plates provided by Alcoa. The main material of the shell of the latest clipper in China also chooses 5083 aluminum. On the basis of 5083 aluminum alloy, 5183, 5283A, 5283B, 5383 aluminum alloys were developed by reducing the impurity content of Fe and Si, slightly increasing the content of Cu and Zn, and adding a small amount of Zr element. Among them, 5383 aluminum alloy has certain formability and corrosion resistance, and its strength and welding performance are better than that of 5083 aluminum alloy. 5086 aluminum, with a magnesium content between 3.5% and 4.5%, is a low magnesium and

3. non-heat treatable alloy. Therefore, the strength of 5086 is higher than that of 5052 aluminum alloy, but the strength is slightly lower than that of 5083 aluminum alloy. 5086 anti-rust aluminum sheet is usually used in the annealed state, cold work hardening or semi-cold work hardening state. Due to the effect of magnesium, the density of 5086 anti-rust aluminum plate is higher than that of other aluminum plates, and it has very good corrosion resistance. 5059 aluminum alloy is currently recognized as the most technically difficult high-end marine aluminum alloy in the industry. Among the aluminum alloy materials listed in CCS "Code for Materials and Welding", the strength index of 5059 aluminum alloy and the strength index of its welding performance are the highest. These aluminum sheet for boat provided by Haomei Aluminum all have he the related certifications like ABS, DNV, LR, CCS,KR,etc. Welcome to leave message below to inquire what you need. Aluminum Foil for Li-ion Battery Battery aluminum foil is mainly used as current collectors in the positive and negative electrodes of lithium batteries and sodium batteries, which have an important impact on battery performance. The internal resistance of the lithium-ion battery directly affects the reliability and cycle life of the battery, which is not only determined by the four main materials of the battery, but also related to the current collector. The current collector is not only the carrier of the active material, but also the conductor of the current generated during operation, which can form a larger current and improve the charging and discharging efficiency of the lithium battery. According to the actual survey data, 300-450 tons of foils for li-ion batteries are needed per GWh. Driven by both new energy vehicles and energy storage, the global demand for battery foil is expected to reach 740,000 tons in 2025, with a compound annual growth rate of 37%. Aluminum foil battery price is determined by the method of "aluminum price + processing fee". At present, the thickness of battery foil is between 8-15μm, the mainstream thickness of overseas electric power battery and energy storage field is 15μm.

4. The thickness and rolling precision of the battery foil are close to those of the traditional light gauge foil. At present, there are two main ways to expand the production capacity of battery foils in the industry: 1. purchase rolling mills and install new equipment; 2. Upgrade the light gauge foil production line to produce aluminum foil for battery. Haomei Aluminum has increased the production capacity of battery foil by adopting the second solution. Compared with the traditional aluminum foil, the battery foil's requirements on the shape and and accuracy are greatly improved. The aluminum foil has high requirements for tensile strength, elongation strength, pinhole, edge trimming, burr, convexity rate, etc. Leading companies like Haomei Aluminum in the industry have more than 10 years of production experience and R&D accumulation. The common aluminum foils for battery include 1070, 1235, 1100, 1060, 3003, HL07, HL08,etc. As a special battery aluminum foil manufacturer, Haomei Aluminum has all the main alloys of battery aluminum foils. Coated Aluminum Strip Coil The coated aluminum strip is a paint coating of various colors attached to the surface of the aluminum coil after cleaning, chroming, roller coating, baking, etc. Since the color aluminum strip is of light texture, bright color and easy processing, it is widely used in aluminum curtain walls, shutters, rolling shutters, aluminum magnesium manganese roofing systems, aluminum ceilings, and household appliances. Smog is made up of all kinds of nitrogen-containing substances, which not only dirty buildings, but also pollutes the air we breathe. PVDF coated aluminum coil has good anti-fouling effect. The protected object can stay clean longer and can be easily washed with water. Haomei PVDF coated aluminum coil has high water repellency, and the dirt on the surface is easily removed by heavy rain. The coating process is a more critical step in the production of colored aluminum coils, which directly affects the final coating quality and product durability. Therefore, the coating process is

5. very strict. With the continuous improvement of coating equipment and the development and utilization of new coatings, the production of coated aluminum coils has become more mature, and the processing cost is also decreasing. In the chemical treatment process, the color aluminum strip adopts neutral treatment agent, roller coating treatment and hot air rapid drying process, which is different from the ordinary dip coating chemical treatment method, effectively eliminating the damage to the environment. Advanced chromium-free treatment liquid is used for surface treatment, which meets strict environmental protection requirements at home and abroad. During the curing process of color-coated aluminum strip, volatile components can be recycled and burned for secondary use, and equipped with advanced VOC desorption system to improve thermal energy utilization. At the same time, it achieves zero emission and eliminates environmental pollution. Since the particularity of the color-coated aluminum strip coil is mainly reflected in the color. In order to avoid the problem of color difference, Haomei Aluminum support free samples for the customer’s reference. We can produce according to the color card number, such as Ral color card (Ral), Pantone color card (PANTONE) or the samples mailed by customers.
