Aluminium round tubes

Aluminiumwerk Unna AG is specialised in the production of Aluminium tubes. The Aluminium tubes are extruded on site using two possible methods. These are either Seamless extrusion or Porthole extrusion. It is quite simple to distinguish between the two extrusion methods. In seamless extrusion, a mandrel is positioned and fixed inside the extrusion die, creating the inner contour of the tube. In porthole extrusion, the mandrel is fixed and is supported by a number of integral bridges affixed to the outer portion of the extrusion die.

Suction lances / suction tubes can be delivered in different diameters right from stock. We also can manufacture according to your drawing and/or sketch or sample. material: stainless steel AISI 304 or aluminium AlMgSi 0.5 F22 in all common tube dimension 40.0 / 50.0 and 60.3 mm right from stock special versions can be realised at short notice and for short delivery]

Novelis is the global leader in rolled aluminum products and aluminum beverage can recycling. Our technical competence and innovation have made us a development partner chosen by leading companies from the automotive, building, printing and packaging industries, among others. With its customer orientation and strong industrial performance, Novelis plays a crucial part in shaping products for the future. The aluminium content means that there is only slight thermal length variation, just like with metal tubes. In addition, the tubes become completely oxygen-impermeable, which is indispensable when connecting radiators, for example. Using state-of-art production facilities and experienced specialists, Novelis ensures top quality in the manufacture of its products – across the entire production process, from casting and processing the ingots via hot and cold rolling, to packaging.
