DIN 1725-1 Grade 3.2305 – Premium E‑AlMgSi Electrical Conductive Alloy
E-AlMgSi is ensured by the German electrotechnical commission as electrical conductive material according to DIN 40 501 part of 1 to part of 4. This cold and warm formable material reaches mechanical strength from 200 to 250 MPa with A5-elongations at break of approx. 10 %. In warm and cold hardened state this alloy is only limited formable, in the soft material condition however well. Weldability, corrosion resistance and anodising ability of this material are good. The alloy E-AlMgSi is ensured by a purposeful heat treatment apart from the strength increase an appropriate high electrical conductivity, so that it is applicable for statically loaded elements in electro-technology. heat treatment for hardening: solution annealing: 525 to 540 °C, quenching in water cold ageing: 5 to 8 d on ambient temperature warm ageing: 4 to 16 h at 155 to 190 °C Application: Electro-technology (overhead line)
