Aluminium tubes
Our core competence!
Aside from the principle of light-weight construction, drawn aluminium tubes meet the highest requirements regarding tight tolerances, low weight, high stability, good corrosion-resistance and high electric and thermal conductivity. These properties make our aluminium tubes essential in many industrial applications as well as in our core market, the automotive industry.
With over 6 decades of experience in the manufacture of seamless drawn aluminium tubes, we face the challenges regarding the functionality of aluminium as a material. We produce according to customer specifications and adapt to meet your requirements. Our technicians will help you select the best material for your application.
Main alloys
| Aluminium alloy in accordance with DIN EN 573-3 | Numerical designation | Typical properties of the aluminium alloy |
|---|---|---|
| EN AW-Al99,5; EN AW-Al99,7 | EN-AW1050A; EN-AW1070A | Aluminium tubes for general applications, particularly high chemical resistance, low stability |
| EN AW-AlMn1 | EN-AW3103 | Higher stability than EN AW-Al 99,5. Same, partly better resistance than EN AW-Al 99,5. Good malleability and suitability for soldering. EN-AW3103 aluminium tubes are frequently found in the automotive industry as liquid-conveying lines. |
| EN AW-AlMn1Cu | EN-AW3003 | Higher stability than EN AW-Al 99,5. Same, partly better resistance than EN AW-Al 99,5. Very malleable. |
| EN AW-AlMg2Mn0,8 | EN-AW5049 | Resistant to sea water. Suitable to handle high stress, easily weldable, good cold forming. |
| EN AW-AlMg2,5 | EN-AW5052 | Relatively high tensile strength, relatively good formability. Good anodising and welding properties; sea water resistant. |
| EN AW-AlMg3 | EN-AW5754 | Good anodising and welding properties; sea water and weather resistant. |
| EN AW-AlMgSi | EN-AW6060 | Heat treatable alloy for Standard applications, especially suitable for decorative anodising. |
| EN AW-AlSi1MgMn | EN-AW6082 | Similar to EN AW-AlMgSi, though with higher stability. Less suitable for decorative anodising than EN AW-AlMgSi. |
| EN AW-AlCu4MgSi(A) | EN-AW2017A | Heat treatable alloy. Guaranteed excellent machining and stress resistance. |
| EN AW-AlZn4,5Mg1 | EN-AW7020 | Heat treatable alloy. Excellently welding properties. |
| EN AW-AlZn5,5MgCu | EN-AW7075 | Heat treatable alloy with almost steel-like properties for particularly demanding applications. |
