FONTARGEN A/AF 314

FONTARGEN A 207 MCu-Si-Mn wire electrode for MIG and MAG weldingEN 14640:S Cu 6511 (CuSi2Mn1)Material-no.: 2.1522Composition, typical analysis (% w/w):Si Sn Mn Cu1,8 0,2 1,0 RemainderCharacteristics / Applications:Very easy to weld. High temperature- and corrosion resistance as well as goodbehaviour under compression stress. Good wetting of the base material with lowerworking temperature compared to copper. Flat seams due to Si content and little poreformation.Welding of galvanised autobody steel sheets (MIG brazing), un-alloyed and lowalloyedsteels, cast iron as well as copper and copper alloys. With MIG burner: Weldsharp, not dragging.Mechanical properties of pure welding deposit(Min. values at RT):Melting range: 1030 – 1050 °CTensile strength:285 N/mm²Yield strength:140 N/mm²Elongation (l=5d): up to 40 %Impact energy:75 JHardness (Brinell):62 HBThermal conductivity:40 W/m KSpecific gravity:8,7 g/cm³Linear expansion: 18,1 10 -6 /KWelding process:MIGShielding gas (DIN EN 439): l 1 (Argon)Current mode:DC (+pole)Availability: Diameter (mm): 0,8/1,0/1,2/1,6/2,4Spool type:B300S300Welding position: according to DIN EN 287PA PB PC PD PE PF PG08/08/Eb/0155
