Sales agency for non-ferrous metals
Stephan Siegele Industrievertretungen is an industrial sales agency founded in 1960 and based in Freiburg im Breisgau, representing European manufacturers of non-ferrous metal semi-finished products in Baden-Württemberg, Rhineland-Palatinate, the Saarland and Switzerland. Its main supplier is Drahtwerk Elisental W. Erdmann GmbH in Neuenrade, whose product range can be customised from the melt to the finished wire. The supply portfolio comprises aluminium wires (round, flat and profile wires, cold-heading wires) from 0.80 to 30.00 mm in diameter, drawn aluminium bars from 3.00 to 22.00 mm as feedstock for precision turned parts and forming processes, as well as aluminium welding filler materials for MIG, TIG, brazing, metallising and WAAM. The alloys cover series 1000 to 8000, plus special materials on request. Supply is accompanied by technical advice on alloy, temper and dimensions, sample provision, approval and standards consulting, as well as series supply with call-off orders and frame agreements. The products are used, among others, in the automotive and commercial vehicle industry, electromobility, aerospace, the railway industry, shipbuilding, tank and container construction and joining technology.
