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. |
