Características de aluminio y aleación de aluminio de ocho series

La proporción de aluminio es ligera., el springback es pequeño, la fuerza es alta, cerca o más que el acero de alta calidad, la plasticidad es buena, cuando la formación del producto es más compleja, es más fácil de controlar que el acero inoxidable, y tiene una conductividad excelente, conductividad térmica y resistencia a la corrosión. En el presente, the surface treatment process of aluminum, such as anodic oxidation, wire drawing, sand blasting, has been very mature, and aluminum is also widely used in mobile phones. According to the processing method, aluminum alloy can be divided into wrought aluminum alloy and cast aluminum alloy. The number of aluminum and aluminum alloy can be divided into eight series.

1000 serie

Entre todas las series, 1000 la serie tiene la mayor cantidad de contenido de aluminio, y su pureza puede alcanzar más de 99.00%. El contenido mínimo de aluminio de 1000 placa de aluminio serie is determined according to the last two Arabic numerals of this series. Por ejemplo, los dos últimos números arábigos de 1050 las series son 50. Según el principio de naming de marcas internacionales, los productos con contenido de aluminio arriba 99.5% debe estar calificado.

El aluminio primario tiene buena conformabilidad y tratamiento superficial., y su resistencia a la corrosión es la mejor entre las aleaciones de aluminio. Cuanto mayor sea la pureza, cuanto menor sea la fuerza.

1050, 1070, 1080, 1085, 1100 se utilizan comúnmente en teléfonos móviles. Simplemente se extruyen (sin agacharse). 1050 y 1100 se puede utilizar para lijado químico, superficie lisa, superficie de niebla, efecto normal, grano de material obvio y buen efecto colorante; 1080 y 1085 El aluminio espejo se usa a menudo para palabras brillantes y efecto de niebla., sin grano de material obvio. Una serie de aluminio es relativamente suave., utilizado principalmente para piezas decorativas o interiores.

2000 serie

It is characterized by high hardness but poor corrosion resistance, among which the original copper content is the highest, y el 2000 series aluminum alloy represents 2024, 2A16 and 2A02. The copper content of 2000 series aluminum plate is about 3-5%. 2000 series aluminum rods are aviation aluminum materials, which are used as structural materials and are rarely used in conventional industry.

3000 serie

3000 series aluminum alloys are mainly composed of manganese. 3000 series aluminum alloy represents 3003, 3105 y 3A21. The content is between 1.0-1.5, which is a series with better antirust function. It is commonly used for tanks and tanks of liquid products, construction processing parts, construction tools, various lamp parts, as well as various pressure vessels and pipes for thin plate processing. The formability, solubility and corrosion resistance are good.

4000 serie

Generalmente, when the silicon content is between 4.5-6.0%, the strength is relatively high when the silicon content is high. 4000 series aluminum alloy represent 4a01 and 4000 series aluminum plates, which belong to the series with high silicon content. Good soup flow, less solidification shrinkage, belongs to building materials, partes mecánicas, forging materials, welding materials; Low melting point, buena resistencia a la corrosión, heat resistance and wear resistance.

5000 serie

5000 series aluminum bar belongs to the more commonly used alloy aluminum plate series, el elemento principal es el magnesio, y el contenido de magnesio está entre 3-5%. 5000 series aluminum alloy represents 5052, 5005, 5083, 5A05 series. También se puede llamar aleación de aluminio y magnesio.. Las principales características son la baja densidad., alta resistencia a la tracción y alta elongación. En la misma zona, the weight of Al Mg alloy is lower than other series, and it is widely used in conventional industry. 5052 is the most commonly used alloy in mobile phones, which is the most representative alloy with medium strength. Tiene buena resistencia a la corrosión., solubility and formability, especially high fatigue strength and sea water resistance. It is often used to make products with high strength requirements, but its coloring effect is not ideal. It is suitable for sand blasting process, not suitable for chemical sand blasting, superficie de niebla, etc, Not suitable for extrusion.

6000 serie

los 6000 series aluminum alloy represents that 6061 mainly contains magnesium and silicon, so it has the advantages of 4000 serie y 5000 serie. 6061 is a cold-treated aluminum forging product, which is suitable for applications with high requirements of corrosion resistance and oxidation resistance. Good usability, easy coating and good processability. 6061 y 6063 are widely used in mobile phones. La fuerza de 6061 es más alto que el de 6063. Using casting molding, it can cast complex structures and make buckle parts, such as battery cover.

7000 serie

It mainly contains zinc. 7000 series aluminum alloy represents 7075. Also belongs to Aviation series, is al mg Zn Cu alloy, is heat treatable alloy, belongs to super hard aluminum alloy, has good wear resistance. En el presente, it basically depends on imports, and the production technology of our country needs to be improved

8000 serie

8011 is more commonly used in 8000 Serie de aleación de aluminio, which belongs to other series. Most of them are used in aluminum foil, but they are not commonly used in the production of aluminum sheet.
