Aluminum classification
 1××× series pure aluminum: representative for 1050, 1060, 1100. In all aluminum series of pure aluminum series is the largest aluminum content of a series. You can reach more than 99.00% purity.

2××× series aluminum alloy: representative 2A16 (LY16), 2A06 (LY6), the characteristics of this series alloys are high hardness, which originally belonged to the highest concentrations of copper, probably in about 3-5%, belong to aviation aluminum conventional industry infrequently used.

3××× series aluminum alloy: representative for 3003, 3004, 3A21. This is a series of alloys of manganese as a main component, the content of 1.0-1.5%. Is a series of anti-rust function better, mainly use in building materials, air conditioners, refrigerators, cars and other wet environments.

4××× series aluminum alloy: representative 4A01. Belong to a higher silicon content of the series. Usually silicon content between 4.5-6.0%, mainly used in construction materials, machinery parts, forging materials, welding materials; low melting point, good corrosion resistance.

5××× series aluminum alloy: representative 5052, 5005, 5083, 5A05. This series belongs to the more commonly used alloy series, the main elements of magnesium, magnesium content between 3-5%, but can be called aluminum-magnesium alloy, the main characteristics of 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 also more widely, processing technology for continuous casting and rolling, hot-rolled aluminum oxide processing series it can do, this series aluminum alloy used for Brushed.

6××× series aluminum alloy: 6061,6063 representative. The main two elements containing magnesium and silicon, so the focus of the 4 ××× series and 5 ××× series of advantages, 6061, a cold finished aluminum wrought product, for corrosion resistance, oxidation resistance demanding applications, you can use good, excellent interface characteristics, easy coating, good process. Widely used in the construction field, can also be used on low-voltage weapons and aircraft connectors.

7××× series aluminum alloy: representative for 7075, mainly containing zinc. Also belongs to the aviation series, aluminum-magnesium, zinc and copper alloy, heat treatable alloy, are super-hard alloy with good abrasion resistance, 7075 aluminum is by eliminating stress, no deformation after processing, warping, all oversized thick 7075 aluminum ultrasonic detection, can guarantee no blisters, impurities, 7075 aluminum thermal conductivity is high, you can shorten the molding time and improve work efficiency. Since the 7075 aluminum alloy with high hardness, high strength, also commonly used in the manufacture of aircraft.
