The majority of aluminum sold in the market is alloyed with one or more additives.
Unalloyed aluminum (pure aluminum) is relatively soft; therefore alloy elements are added or a cold working process is carried out to increase the strength.
| Element | Description | Type |
|---|---|---|
| Pure aluminum | 1000-batch | Non-hardenable |
| Cobber | 2000-batch | Hardenable |
| Manganese | 3000-batch | Non-hardenable |
| Silicon | 4000-batch | Non-hardenable |
| Magnesium | 5000-batch | Non-hardenable |
| Magnesium + silicon | 6000-batch | Hardenable |
| Zink | 7000-batch | Hardenable |
| Other alloy elements | 8000-batch |
There is a vast difference between how suitable the different alloys are for the wanted application.
The chart below provides some indications, but no guarantees.
| Type of delivery | Description |
|---|---|
| EN AW-1050A DDQ: | Contains 99,5 % aluminum while soft, and is mainly used for subjects that need to be deep-drawn. It comes in the following thicknesses: 1.00 mm, 1.25 mm, 1.05 mm and 2.00 mm.

It is an alloy with short shavings, that is suited for machining processes, threads, and fast processing speeds. The alloy is low-level corrosion-proof and is not suited for welding due to the high level of copper. It is not approved according to ROHS. |
| EN AW-2011 | Is a copper alloy that typically contains between 4.0 and 5.0 % copper and is suited for the production of machine parts, bolts, and rivets. It is very similar to EN AW-2011 but is softer. It is an alloy with short shavings, that is suited for machining processes, threads, and fast process speeds and it gives a burnished surface after the treatment. It has a high level of strength against metal fatigue. The alloy is low-level corrosion-proof and is not suited for welding due to the high level of copper. It is approved according to ROHS in some cases. |
| EN AW-2014 | Is a copper alloy that typically contains between 4.0 and 5.0 % copper. It is an alloy with short shavings, that is suited for machining processes, it is strong and is similar to EN AW-2011 and EN AW-2007. It is harder than EN AW-2011.The alloy is typically used for military purposes and in the aviation industry. It is approved according to ROHS. |
| EN AW-2017A | Is a copper alloy that is high in copper. It is an alloy with short shavings, that is suited for machine processing. The alloy is low-level corrosion-proof and is not suited for welding due to the high level of copper. It is not suited for decorative anodising. |
| EN AW-2024 | Is a copper alloy that is high in copper. It is an alloy with short shavings, that is suited for machine processing. The alloy is low-level corrosion-proof and is not suited for welding due to the high level of copper. It is not suited for decorative anodising. |
| EN AW-3003 | Is a manganese alloy that is high level corrosion-proof. The alloy has medium strength and is suited for welding and bending. |
| EN AW-3005 | Is a manganese alloy that is high level corrosion-proof. The alloy has medium strength and is suited for welding and bending. |
| EN AW-3103 | Is a manganese alloy that is high level corrosion-proof. The alloy has medium strength and is suited for welding and bending. |
| EN AW-3105 | Is a manganese alloy that is high level corrosion-proof. The alloy has medium strength and is suited for welding and bending. |
| EN AW-5005 | Is a manganese alloy that is high level corrosion-proof. The alloy has medium strength and is suited for welding and bending. |
| EN AW-5005A | Suited for processing and bending and has a high corrosion constancy as well as being suitable for welding. |
| EN AW-5052 | Easy to process and is high level corrosion-proof as well as being suitable for welding. The alloy is not suited for anodising. |
| EN AW-5083 | Is sea-water-proof and has a medium level of strength, is high level corrosion-proof and is suited for welding. The alloy is averagely suited for anodising. |
| EN AW-5083 | Is a moulded alloy with low tension, that is exceptionally well-suited for processing. It is recommended to use the same batch for concrete projects. |
| EN AW-5086 | Is sea-water-proof and has a medium level of strength, is high level corrosion-proof and is suited for welding. The alloy is averagely suited for anodising. |
| EN AW-5754 | Is sea-water-proof and has a medium level of strength, that is high level corrosion-proof and is suited for welding. The alloy is averagely suited for anodising. |
| EN AW-5754 CastEN AW-6005A | Is an alloy that is medium level corrosion-proof that is well-suited for welding. The alloy’s strength is higher than that of EN AW-6063. |
| EN AW-6026 | It is an alloy with short shavings and high strength, it is medium level corrosion-proof and is averagely suited for welding and anodising. |
| EN AW-6060 | Is well-suited for decorative anodizing and is high level corrosion-proof. The alloy is well-suited for welding. |
| EN AW-6061 | Is well-suited for decorative anodizing and is high-level corrosion-proof and is well-suited for anodising. The alloy is well-suited for welding. |
