ÖNORM EN 1715-1

This part of EN 1715 specifies the general drawing stock characteristics to be satisfied by unalloyed aluminium and aluminium alloy drawing stock delivered in the form of coils with a unit weight ranging between i t and 3 t and obtained by common industrial processes. It also specifies the technical conditions for inspection and delivery of these products. These general characteristics and conditions apply to drawing stock intended for the following three main fields of application : - electrical conductors of aluminium and aluminium alloys ; - wires for general mechanical uses ; - wires for brazing and welding. The specific requirements to drawing stock for these applications are specified in parts 2, 3 and 4 of EN 1715. It does not apply to wires which are drawn, but only to drawing stock which is produced by hotworking. NOTE 1 : Manufacture of drawing stock : Wo main methods exist for the manufacture of drawing stock : - continuously Cast Rod - (CCR) : a section is Cast continuously in the groove of a wheel, the groove being closed by an endless strip ; the solid and still hot section is rolled in a multistand rolling mill to the required diameter ; the drawing stock rod thus produced is wound continuousfy to form coils I t to 3 t in weight ; - hot rolled Rod - (HRR) : a wirebar of diameter 100 mm to 150 mm is heated and rolled to the required diameter ; the coils produced, weighing up to about 100 kg are butt welded together and wound to form coils with unit weight of I t to 3 t. NOTE 2 : It is also possible to obtain drawing stock by extrusion.
