FONTARGEN A/AF 314

FONTARGEN A 512/30 MCopper-nickel welding rod for MIG weldingEN 14640:S Cu 7158 (CuNi30)Material-no.: 2.0837Composition, typical analysis (% w/w):Ni Fe Mn Si Ti Cu30 0,5 1,0 0,1 0,3 RemainderCharacteristics / Applications:Corrosion- and saltwater-proof alloy. A512/30 M is very easily machined. The weldpool is clean. The welding deposit is tough and non-porous.Joint and build-up welding on copper-nickel alloys up to a Ni content of 30%. Materialnumbers 2.0806, 2.0812, 2.0818, 2.0822, 2.0830, 2.0836, 2.0842, 2.0862,2.0872, 2.0878, 2.0882, 2.0890. In the shipbuilding and chemical industries, e.g.containers, condenser tubes, radiators, heat exchangers, etc. For welds with unalloyedmaterials buffer the edges of the weld seam of the unalloyed base material with asuitable filler metal, e.g. SG-NiCu 30 Mn Ti = A511 M. For build-up welds on ferrousmaterials it is possible to direct the arc to the edges of the preceding pass. Pulsed-arcwelding recommended. Also suitable for build-ups on cast iron.Mechanical properties of pure welding deposit(Min. values at RT):Melting range: 1180 – 1240°CTensile strength:380 – 480 N/mm²Yield strength (0,2):200 N/mm²Elongation (l=5d): 30 %Thermal elongation: 16 p 10 -6 /KImpact energy:100 JElectrical conductivity:3 Sm/mm²Heat conductivity:35 W/m • KWelding process:MIGShielding gas (DIN EN 439): l 1 (Argon); Ar-H 2 -mixtureCurrent mode:Direct current (+pole)Availability: Diameter (mm): 1,0/1,2Spool type:B300Welding position: according to DIN EN 287PA PB PC PD PE PF PG08/08/Eb/0161
