Aluminium Material
Aluminium material is widely using in architecture and industrial areas. From the GB/G16474-1996 standard, which according the International Aluminium Alloy Code Registration Consultation Organization recommended 4 digits for the international aluminium alloy code system.
The first digit of alloy codes represented aluminium and aluminium alloy's group difference as the form showed below:

1050A |
This is the most common alloy for aluminium sheet. It has great corrosion resistance and is also very formable and easy to weld. The fields of application in industry are very large and varied. |
|
2007 |
Equal to EN 2011. Gives slightly longer shavings/granules/particles but has a 20 per cent higher breaking point, which is an advantage when stronger threads are required. It is a very common alloy in the rest of Europe and is mainly used for hydraulic and pneumatic components. |
|
2011 |
This is the most suitable alloy for cutting which has the great advantage of tensile strength and very short shavings/granules/particles. The corrosion resistance is not so good and welding is not recommended. This alloy is not suitable for decorative anodizing, however it can be anodized to increase the serviceable life of wearing surfaces and improve corrosion resistance. |
|
2014 |
A suitable alloy for cutting, which also has the advantage of tensile strength. A common alloy within the defence and aircraft industry. Corrosion resistance is not so good and welding is not recommended. |
|
2024 |
This alloy is mostly used in the defence and aircraft industry. |
|
5005 |
An alloy for the decorative anodizing of sheet aluminium. It has approximately the same qualities as EN 1050A, but with greater tensile strength. It can be used for facings, signs, panels and parts of components requiring a special finish. |
|
5083 |
Very high resistance against corrosion used in marine environments. It also has the advantage of tensile strength. Particle breaking is better than with alloy EN 5754. This is a material with minimal strains and very good welding properties. It can be used, for example, for boats, machine parts, fixtures and tools. It is available in sheets of up to 500 millimetres in thickness. |
|
5754 |
An alloy with high resistance against corrosion and good welding properties. It is relatively easy to work with and is good for cutting. It also has the advantage of tensile strength. It is suitable for marine environments. It is a common alloy in thicker sheets for machine parts and in thinner sheets that require greater strength. |
|
6005 |
Is equivalent to alloy EN 6063, but slightly stronger. It has better cutting properties and retains its surface finish after anodizing. |
|
6012 |
These are both short particle alloys that have excellent cutting qualities. |
|
6262 |
Corrosion resistance is good and both alloys are suitable for decorative anodizing. |
|
6063 |
This is the most common alloy for extruded profiles. It is used for constructions which require good tensile strength and surface finish. It is suitable as profiles for windows, doors, equipment parts and chassis in the electronics industry. |
|
6463 |
This is the best alloy which could bring out the highest brightness from polishing process. When the surface treatment concerned. |
|
6082 |
A good alloy where demands for tensile strength and good cutting characteristics are higher. It is to be found in sheet, bars and profiles. Used in load bearing constructions and for finished machine parts that require a good surface finish after anodizing. A certain in-built tension can occur in rolled products. |
|
7020 |
A suitable alloy for welded joints where high tensile strength is required. Welded constructions should be protected against corrosion. The alloy also has good characteristics in terms of cutting and other processing. |
|
7022 |
This is an alloy with very good qualities of tensile strength, high breaking point and good cutting properties. |
|
7075 |
This is one of the hardest and strongest aluminium alloys. It is often used instead of steel within the aircraft industry and in the production of tools. It has a very high tensile strength, low weight and is ideally suited to all types of further processing. The alloy also has good stability of form and can be hard anodized. |
