The main elements are aluminum-magnesium alloy of aluminum, then mixed with a small amount of magnesium or other metal materials to enhance its hardness. Adding Mg to the aluminum alloy as the main element, since it has good corrosion resistance, also known as rust-proof aluminum alloy. By itself is metal, its thermal performance and strength is particularly prominent.
Characteristics
Aluminum-magnesium alloy aluminum hard and lightweight, low density, good heat dissipation, resistance is strong, can fully meet the 3C products highly integrated, lightweight, miniaturization, and drop collision and electromagnetic shielding and heat dissipation requirements. Its hardness is the traditional plastic enclosure several times, but weighs only one-third of the latter.
1 aluminum-magnesium alloy applications
Electronic Products
Is often used in high-end ultra-thin notebook or smaller sized shell. Moreover, silver magnesium alloy casing make the product more luxurious, beautiful, and easy to color, surface treatment process can become personalized powder blue and pink, for laptops considerably, which is plastic and carbon fiber unmatched. Thus become the preferred aluminum-magnesium alloy shell material portable laptop, notebook manufacturers now most products are used magnesium alloy shell technology. Disadvantages: not very rugged magnesium alloy wear-resistant, high cost, relatively expensive and difficult than ABS molding (requires stamping or die casting process), so the laptop is generally only used on the aluminum-magnesium alloy cover, with little there are models to produce the entire chassis with aluminum-magnesium alloy.
Doors and windows
Excellent performance aluminum-magnesium alloy, high strength, corrosion resistance, durable, easy coloring, used to make high-end doors and windows, doors and currently more famous phoenix aluminum profile manufacturers in Guangdong, Zhejiang Dongliang, Suzhou ropes, etc.
2 types of aluminum-magnesium alloy
Aluminum-magnesium alloy can be called 5 ××× series aluminum alloy, its representative has 5052 aluminum, 5005 aluminum, 5083 aluminum, 5754 aluminum, 5A02l aluminum, 5A05 aluminum and so on. Aluminum-magnesium alloy aluminum alloying elements mainly magnesium, magnesium content between 3-5%. The main features of the low density, high tensile strength, elongation. In the same area weight magnesium alloy lower than other series .. It is commonly used in aviation, such as aircraft fuel tanks. In conventional industrial applications are more widely. Process for the continuous casting and rolling, hot-rolled aluminum oxide processing series it can do. In China 5 ××× series aluminum is aluminum, one of the more mature series.
3 aluminum-magnesium alloy introduced species
1,5052 aluminum-magnesium alloy: 5052 aluminum is aluminum-magnesium alloy, using a wide range, in particular aluminum alloy construction industry can not do without, and it is the most promising combination of aluminum gold plate. The main alloying elements for 5052 aluminum with magnesium, has good corrosion resistance, weldability, cold is better, and has a moderate intensity.
5052 aluminum commonly used in the manufacture of aircraft and automotive fuel tanks, fuel lines, and transportation vehicles, vessels of sheet metal parts, instruments, lights bracket and rivets, metal products, electrical appliances, such as Shell.
2,5005 aluminum-magnesium alloy aluminum: Aluminum 5005 and 3003 considerable strength, weldability, good processability 5005 and 3003 aluminum alloy similar, with moderate strength and good corrosion resistance. Anodic oxide film brighter than the oxide film on the 3003 alloy and tone coordinated with 6063 alloy.
5005 aluminum conductor used as terms, cookware, dashboards, shell and architectural decoration pieces, interior and exterior building materials, timber, vehicle interior materials and so on.
3,5754 aluminum-magnesium alloy: 5754 aluminum alloy with moderate strength, good corrosion resistance, weldability and ease of processing shape and other characteristics of Al-Mg alloy typical alloys. In other countries, different heat treatment of aluminum alloy sheet 5754 is the automotive industry (car door, dies, seals), the main material used in canning industry.
5754 aluminum is widely used in welded structures, storage tanks, pressure vessels, ships and offshore facilities construction, transport tank and for requiring excellent processing performance, excellent corrosion resistance, high fatigue strength, weldability and high static strength of the medium occasions.
4,5083 aluminum-magnesium alloy: 5083 aluminum with the highest intensity in the non-heat-treated alloy, corrosion resistance, good weld. For the need to have high corrosion resistance, good weldability and moderate-intensity occasions, hardness significantly higher than 5052 series, 5000 series, one of the super hardness aluminum representative products.
5083 aluminum commonly used in ships, vessels, vehicles, timber, automotive and aircraft plates welded parts, should be strictly fireproof pressure vessel, refrigeration equipment, tower, drilling equipment, transportation equipment, missile components, and armor.
