Description

Material EN AW-Al Mg2 is produced for sheet metals, strip and plates, for HF-welded tubes, for wire and prewire for mechanical applications, for extruded and drawn components. The material is food-safe and is used for prematerial for cans, caps and stoppers. To the comparable mark AlMg2Mn0,3, material No. 3.3525 acc. to DIN 1725-1 : 1983-02 applies: The alloy AlMg2Mn0,3 is similar to alloy AlMg1,8. Mn-addition causes strength increase for extrusion products and hightened high-temperature strength of the material. It has a high resistance to corrosion, seawater and salted atmosphere. Strength increases and cold workability decreases according to the Mg-content. It is naturally hard, i.e. a strength increase can only be achieved by cold forming, not by controlled heat treatment. Machinability and weldability are enhanced by increasing Mg-content. Application: for metal goods (incl. harness), in food industry (incl. commercial devices). For transport containers, in packaging industry as tins as well as for signs (e.g traffic signs).
