Aluminium and its alloys - aluminium tubes - Import export

In the aluminium industry, the porthole extrusion process is the standard method for the production of extruded tubes and profiles. The process is limited to a number of aluminium alloys. However, most of the commercially available medium strength aluminium alloys such as EN AW-6060 or EN AW-6082 can be extruded by porthole extrusion.

By creating specialized aluminum alloys, pioneering new treatments and combining aluminum components with other materials such as paper, plastic and fiberglass, Novelis has become the global quality leader for the transportation manufacturing industry. We have created a range of transportation manufacturing products that provide insulation against heat, sound and gases, high strength so components remain effective under pressure, and superior flexibility for a full range of designs and implementations. Key Novelis aluminum components include heat exchangers, heat protection mats and sleeves, energy absorption elements, hoses, silencers and flexible tubes, including heat protection tubes, air ducts and exhaust pipes. Novelis is a leading supplier of light-gauge, narrow-slit aluminum fin stock (bare and clad) and brazing sheet used in the production of heat exchangers.

Heat protection tubes are made by layering several kinds of aluminum alloy foil and other materials, such as fiberglass and plastic with corrugations. The excellent reflectivity of the aluminum alloy on the external surface reflects radiant heat, and its insulating power additionally serves to protect the aluminum flexible tube’s content from heat sources. These products have great flexibility but high dimensional stability, and they can be compressed or extended as required. They can also be fastened or mounted easily by crimping the end fittings.
