1000-9000 series aluminum alloy brief introduction

1000-9000 series aluminum alloy brief introduction

Aluminum alloys are obtained by adding different elements on the basis of pure aluminum. Aluminum alloys can be classified into 1000-9000 series aluminum alloys through different added elements. Different series of aluminum alloys have different properties. Next, let’s briefly understand 1000-9000 series aluminum alloy:

1000 series aluminum alloy

1000 series aluminum alloy: features: more than 99.00% aluminum, good electrical conductivity, good corrosion resistance, good welding performance, low strength, no heat treatment strengthening. Application range: high-purity aluminum (aluminum content above 99.9%) is mainly used in scientific research Experimental, chemical industry and special purpose.

1050 aluminum alloy

1000 series aluminum alloys include:

• 1050 aluminum alloy
• 1060 aluminum alloy
• 1100 aluminum alloy
• 1235 aluminum alloy

2000 series aluminum alloy

2000 series Features: An aluminum alloy containing copper as the main alloying element. Manganese, magnesium, lead and bismuth are also added for machinability.

For example: 2011 alloy, pay attention to safety protection during the smelting process (hazardous gas will be produced).

2014 alloy used in aerospace industry, high strength.

The 2017 alloy is a bit weaker than the 2014 alloy, but is easier to machine.

2014 can be strengthened by heat treatment.

Disadvantages: Intergranular corrosion tends to be serious.

Application range: aviation industry (2014 alloy), screw (2011 alloy) and industries with high service temperature (2017 alloy).

2000 series aluminum alloys include:

• 2A12 aluminum alloy
• 2014 aluminum alloy
• 2017 aluminum alloy
• 2024 aluminum alloy

3000 series aluminum alloy

3000 series Features: Aluminum alloy with manganese as the main alloying element, which cannot be strengthened by heat treatment, has good corrosion resistance and good welding performance.

Good plasticity. (close to super aluminum alloy).

Disadvantages: low strength, but can be strengthened by cold work hardening. Coarse grains are easily produced during annealing.

Application range: oil guide seamless pipe (alloy 3003) and cans (alloy 3004) used in aircraft.

3000 series aluminum alloys include:

• 3003 aluminum alloy
• 3004 aluminum alloy
• 3005 aluminum alloy
• 3104 aluminum alloy
• 3105 aluminum alloy

4000 series aluminum alloy

4 series: silicon-based, not commonly used. Some 4-series alloys can be strengthened by heat treatment, but some 4-series alloys cannot be heat-treated.

4 series aluminum alloys include:

• 4032 aluminum alloy

Series 5000 Features: Magnesium-based. Good resistance, good welding performance, good fatigue strength, can not be strengthened by heat treatment, only cold working can improve the strength.

Applications: lawn mower handles, aircraft fuel tank conduits, body armor.

5000 series aluminum alloy

5 series aluminum alloys include:

• 5005 aluminum alloy
• 5052 aluminum alloy
• 5083 aluminum alloy
• 5086 aluminum alloy
• 5182 aluminum alloy
• 5454 aluminum alloy
• 5754 aluminum alloy

1000-9000 series aluminum alloy

6000 series aluminum alloy

Series 6000 Features: Mainly magnesium and silicon. Mg2Si is the main strengthening phase and is currently the most widely used alloy.

6063 and 6061 are used the most, others 6082, 6160, 6125, 6262, 6060, 6005, and 6463. 6063, 6060, and 6463 have relatively low strength in the 6000 series.

6262, 6005, 6082, and 6061 have relatively high strength in the 6000 series. The mid-end shelf of Cyclone No. 2 is 6061 aluminum.

Features: medium strength, good corrosion resistance, good welding performance, good process performance (easy to extrude and form), good oxidation and coloring performance.

Application range: energy transfer tools (such as: car luggage racks, doors, windows, car bodies, heat sinks, box shells)

6 series aluminum alloys include:

• 6061 aluminum alloy
• 6063 aluminum alloy
• 6082 aluminum alloy

7000 series aluminum alloy

7000 series Features: Mainly zinc, but sometimes a small amount of magnesium and copper are added.

Among them, superhard aluminum alloys contain zinc, lead, magnesium and copper alloys close to the hardness of steel.

The extrusion speed is slower than that of the 6-series alloy, and the welding performance is good.

7005 and 7075 are the highest grades in the 7 series, which can be strengthened by heat treatment.

Applications: Aviation (force-bearing components of aircraft, landing gear), rockets, propellers, and aerospace vehicles.

7 series aluminum alloys include:

• 7075 aluminum alloy

9000 series aluminum alloy

9 series: (spare alloy)
