Aluminum 2000 series

2000 series aluminium grades contain 0.7-6.8% copper and small amounts of silicon, manganese, magnesium, and other elements. Copper is the alloying element for these grades; it imparts additional strength and hardness, improving their machinability. The high strength of these grades is maintained at a wide range of temperatures.
2000 series aluminium grades are high-performance and high-strength alloys; hence, they are suitable for aircraft and aerospace applications. However, the addition of copper also decreases ductility and corrosion resistance.
The 2000 series are heat-treatable aluminium grades. Precipitation hardening can be performed to increase their strength. The precipitation of the intermetallic Al2Cu during heat treatment increases the hardness of the alloy. However, the intermetallic compounds can make these grades challenging to weld. Some 2000 series grades are not suitable for arc welding because of their susceptibility to hot cracking and stress corrosion cracking.

• Aluminum 2011 is a free-machining alloy. It has excellent machinability properties (i.e., it generates small chips and gives a better surface finish), making it suitable for high-speed lathing. This grade is a highly versatile alloy. However, it has poor corrosion resistance, which can be solved by coating or anodizing. They are not recommended for forming and welding.
• Aluminum 2024 is one of the most widely known high-strength aluminium alloys. This alloy has good fracture resistance, fracture toughness, and low fracture crack growth. It is ideal for heavy-duty applications under stress for prolonged periods. However, it also has poor corrosion resistance, which can be mitigated by cladding or anodizing.

Corrosion Resistance Aluminium 2011

In comparison to other commercial grades of aluminium, grade 2011 has poor corrosion resistance. Parts that are manufactured from grade 2011 alloy are often anodised in order to help protect the surface of the metal. Should the extra strength of grade 2011 not be critical, then grade 6082 which has excellent corrosion resistance should be considered.

Corrosion Resistance Aluminium 2017

Aluminium 2017 has excellent corrosion resistance due to its high aluminium content as well as its protective coating created by the zinc component in the alloy’s composition. This makes it perfect for use in corrosive environments such as saltwater or acidic atmospheres where other metals would only succeed quickly with proper maintenance and protection.

Corrosion Resistance Aluminium 2024

Aluminium 2014 and 2024 are susceptible to corrosion, but 2024 is less resistant. Therefore, proper surface treatments are crucial with this alloy to provide adequate protection. By contrast, Aluminium 2014 has excellent corrosion resistance and can readily be used outdoors. This makes 2014 an excellent choice for applications that require resistance to harsh or corrosive environments, such as marine or coastal structures.

Corrosion Resistance Aluminium 2048

Aluminum 2048 has excellent corrosion resistance when exposed to air or water thanks to its passivation layer formed on the surface by the reaction between oxygen molecules present in the atmosphere and aluminium atoms present on the alloy surface forming protective layers that prevent further oxidation processes even when exposed continuously over long periods.

Corrosion Resistance Aluminium 2219

Aluminium 2219 is a great choice for applications that require superior corrosion resistance. This grade of aluminium alloy is heat-treatable, and its properties include high strength and good machinability. Its primary alloying element, copper, provides excellent corrosion resistance in all environments except a few, like hydrochloric acid and sulfuric acid. All of this makes Aluminium 2219 a preferred material for many applications, especially those that involve long-term use or exposure to harsh external elements. Furthermore, its low weight and high strength make it an attractive choice for many industries.

Types of Aluminum Alloys

There are 7 main types, or series, of wrought aluminium alloys. Each series can contain hundreds of unique alloys, each of which can be defined by a simple code as per the figure below

Conclusion

2000 series aluminium plate is characterized by high hardness, in which the original content of copper is about 3-5%. 2000 series aluminium rod belongs to aviation aluminium material, which is not often used in conventional industry at present.

For an engineer or part designer, series numbers are the most important topic to understand. Temper and age conditions are somewhat set in stone, and engineers typically don’t specify these in the design stage, except in very specific circumstances. For example, if you would like a part to be made from 6061 aluminium, it is likely going to be of the 6061-T6511 designation. Engineers should also understand the shapes and sizes of alloys available.

Aluminium is a common metal that combines robust mechanical properties with relatively low weight and low cost. It is almost three times lighter than steel, making it one of the go-to material choices in aerospace, automotive, and other applications requiring low weight. Aluminium alloys are most often extruded, rolled (cold-formed), or cast – each of which can have profound impacts on material behaviour. Other factors such as alloy composition and heat treatment can further modify the performance of an alloy.
