FONTARGEN A 404/4,5 ZR MAluminium-magnesium wire electrode for MIG-weldingEN ISO 18273:S Al 5087 (Al Mg 4,5 Mn ZR)AWS A 5.10: ER 5087Material-no.: 3.3546Composition, typical analysis (% w/w):Mg Mn Fe Si Cr Ti Zr Al4,7 0,9 0,2 0,1 0,1 0,1 0,15 RemainderCharacteristics / Applications:Zirconic welding deposit for joints which demand highest toughness. Zirconium increasesthe heat crack-resistance. The welding filler can be used advantageously for complicatedwelding constructions involving unfavourable restraint conditions. The welding deposithas a good resistance to atmospheric influences and seawater.Joint welding on rolled and cast aluminium-magnesium alloys, e.g. Al Mg 3, G-Al Mg 3,Al Mg 4,5 Mn, Al Mg 5, G-Al Mg 5, Al-Cu Mg 1, Al Mg Si 1, Al Zn 4,5 Mg 1. If platesare thicker than 10mm preheat to 150°C – 200°C.Mechanical properties of pure welding deposit(Min. values at RT):Melting range: 574 – 638°CTensile strength:300 N/mm²Yield strength (0,2%):140 N/mm²Elongation (l=5d): 20 %Electrical conductivity:17 – 19 Sm/mm²Heat conductivity:110 – 120 W/m • KSpecific gravity:2,66 g/cm³Linear expansion: 23,7 • 10 -6 /KWelding process:MIGShielding gas (DIN EN 439): l1 (Argon)I 3 (Argon/Helium mixture)Current mode:Direct current (+pole)Availability: Diameter (mm): 0,8/1,0/1,2/1,6/2,4Spool type:B300Welding position: according to DIN EN 287PA PB PC PD PE PF PG08/08/Eb/0166
