1 Series: 1060 1070 1100, etc.

Features: 99.00%aluminum, good conductivity, good corrosion resistance, good welding performance, low strength, non -heat treatment reinforcement. Because it does not contain other technical elements, the production process is relatively single and the price is cheaper.

Scope of application: high -pure aluminum (more than 99.9%of aluminum volume) is mainly used for scientific experiments, chemical industry and special purpose.

2 Series: 2017 2024, etc.

Features: Aluminum alloy with copper as the main alloy element. (The amount of copper is between 3-5%) will also add manganese, magnesium, lead, and 铋 for cutting.

Such as: 2011 alloys, pay attention to safety protection during the melting process (will generate harmful gases). In 2014, alloys are used in the air industry with high strength. The 2017 alloy is a little lower than the 2014 alloy, but it is easier to process. 2014 heat treatment reinforcement.

Disadvantages: Crystal corrosion tendency is serious. Scope of application: Aviation Industry (2014 alloy), screws (2011 alloys) and industries with high temperature (2017 alloy).

3 Series: 3003 3004 3005, etc.

Features: Aluminum alloy (manganese content is 1.0-1.5%) with manganese as the main alloy element. Do not heat up and strengthen, good corrosion resistance, good welding performance, good plasticity (close to ultra -aluminum alloy).

Disadvantages: low strength, but can strengthen the strength through cold processing hardening; it is easy to produce large grains during annealing.

Scope of application: Oil guide tube (3003 alloys) used on the aircraft, cans of jar (3004 alloy).

4 Series: 4004 4032 4043

4 × × × aluminum alloy is an aluminum alloy with silicon as the main alloy element (the silicon content is between 4.5-6).

Most of the metal metals are not enhanced with aluminum alloy. Only alloy containing copper, magnesium and nickel, and welding thermal treatment enhanced alloys can be strengthened by heat treatment.

Due to the high silicon content, low melting point, the melting point is low, the melting point is good, it is easy to shrink, and it will not make the final product brittle. Therefore, it is mainly used for adding materials for the manufacturing aluminum alloy welding, such as 钎 welding plates, stripes, and welded strips and stunts and stunts and stunts and stunts and stunts. Welding wires, etc.

In addition, due to the good wear resistance and high temperature performance of some alloys, it is also used to make piston and heat -resistant parts. The alloy of about 5%silicon contains black gray after the anode oxidation is colored. Therefore, it is suitable for building materials and manufacturing decorative parts.

5 Series: 5052 5083 5754

Features: Magnesium is the main (magnesium content between 3-5%).

Low density, high tensile strength, high extension rate, good welding performance, good fatigue strength, not heat treatment and reinforcement, can only increase the intensity of cold processing.

Scope of application: the handle of the grass cutting machine, aircraft fuel tank catheter, cans, bulletproof coats, etc.

Generally, the shoe racks of the middle and above are basically 6 Series or 7 Series

6 Series: 6061 6063

Features: mainly magnesium and silicon.

MG2Si is the main enhancement phase, and currently has the most widely used alloy.

6063, 6061 the most, other 6082, 6160, 6125, 6262, 6060, 6005, 6463.6063, 6060, 6463 in the 6 Series is relatively low. 6262, 6005, 6082, 6061 is relatively high in 6 Series. The middle shelf at the Type 2 is 6061

Features: medium strength, good corrosion resistance, good welding performance, good process performance (easy to squeeze out formed) oxidation and coloring can be good.

Application scope: Jiaotong tools (such as: car luggage racks, doors, windows, body, body, heat sinks, box shells, mobile phone cases, etc.)

7 Series: 7050 7075

Features: mainly zinc, but sometimes a small amount of magnesium and copper are added. Among them, ultra -hard aluminum alloy contains the hardness of zinc, lead, magnesium, and copper alloy near steel.

The squeezing speed is slower than the 6 series alloys, and the welding performance is good.

7005 and 7075 are the highest grades in the 7 Series, which can be treated with heat.

Scope of application: aviation (aircraft's bearing components, landing gear), rockets, propeller, aerial spacecraft.

8 Series: Other alloys

8011 (rarely uses aluminum plates, generally used as aluminum foil)

Uses: Air conditioning aluminum foil, etc.
