<strong>FONTARGEN</strong> A 207 WCopper-silicon-manganese welding rodEN 14640:S Cu 6511 (CuSi2Mn1)Material-no.: 2.1522Composition, typical analysis (% w/w):Si Sn Mn Cu1,8 0,2 1,0 RemainderCharacteristics / Applications:Easy to weld. High temperature- and corrosion resistance as well as good behaviourunder compression stress. Good wetting of the base material with low workingtemperature compared to copper. Flat seams due to silicon content. Little pore formation.Welding deposit has good modelling properties.Welding of galvanised autobody steel sheets, other steels as well as copper, copperalloys and cast iron.Mechanical properties of pure welding deposit(Min. values at room temperature):Melting range: 1030 – 1050 °CTensile strength:285 N/mm²Yield strength:140 N/mm²Elongation (l=5d): 45 %Hardness (Brinell):62 HBElectrical conductivity: 4,7-5,3 Sm/mm 2Heat conductivity:40 W/m KSpecific gravity:8,7 g/cm³Coefficient of expansion: 18,1 10 -6 /KWelding process:TIGShielding gas (DIN EN 439): l 1 (argon)Current mode:Direct current (-pole)Availability: Diameter (mm): 1,6/2,0Length (mm): 1000Welding position: according to DIN EN 287PA PB PC PD PE PF PG06/08/Eb/0190
