FONTARGEN A 314Silver brazing alloy, cadmium freeDIN EN 1044: AG 103DIN 8513:L-Ag 55 SnEN ISO 3677: B-Ag 55 Zn Cu Sn – 630/660Material-no.: 2.5159Composition, typical analysis (% w/w):Ag Zn Cu Sn Si55 22 21 2 0,15Mechanical and physical properties:Working temperature: 650°CMelting range: 630 – 660°CSpecific gravity:9,4 g/cm³Tensile strength:330 – 430 N/mm²Elongation: 25 %Electrical conductivity:7 S m/mm²Hardness:110 BHNCharacteristics / Applications:Silver-bearing, cadmium-free low melting brazing alloy, insensitive to overheating forgap and joint brazing of alloyed and unalloyed steel, nickel and nickel alloys, malleablecast iron, copper and copper alloys and carbides. Brazing stainless steel provides thebest possible colour match. Suitable for brazed joints which will be used in seawateraccording to marine code VG 81245, section 3. The absence of cadmium makes itespecially suitable for joints destined to come in contact with food. The silicon containedin the solder can reduce the mechanical property values of welded carbon steels. Forbrazing joints with a working temperature of max. 200°C.Heat sources:Acetylene torch, air-gas torch, induction and resistance heatingFlux:F 300 – SeriesApproval:Marine code VG 81245, section 3Availability:Bare Coatedrods rodsWire Foil Preforms Powder Paste07/08/SR/039
