This European Standard specifies general requirements for drawing stock of aluminium and aluminium alloys delivered in the form of coils with a unit mass ranging between 1 t and 4 t and obtained by common industrial processes.It also specifies the technical conditions for inspection and delivery of these products.It applies to drawing stock intended for the following main fields of application:wires for general electrical purposes;wires for general mechanical uses;wires for brazing and welding and metal spraying;food packaging.The specific requirements to drawing stock for these applications are specified in EN 1715-2, EN 1715-3 and EN 1715-4.It does not apply to wires which are drawn, but only to drawing stock which is produced by hot-working.NOTEThree main methods exist for the manufacture of drawing stock:a)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 continuously to form coils up to 4 t in mass;b)hot rolled rod (HRR):a wirebar of diameter approximately 100 mm to 150 mm is heated and rolled to the required diameter;the coils, weighing up to approximately 100 kg are butt welded together and wound to form coils with mass of 1 t to 4 t;c) hot extruded rod (HER):coils up to 100 kg can be produced in a single fibre without butt welds (depending on the size of the extrusion press);coils over 100 kg are normally produced by block on block extrusion, generating "Zweiwachs"-joints. For mechanical applications (i.e fasteners) the "Zweiwachs" area should be marked.
