Joining thick to thin sections requiring a combination of braze-welding and brazing techniques. Brazing Techniques: Clean the surface and preheat heavy sections. Adjust the torch to a neutral to slightly carburizing mixture.
2197 – Green Flux Coated Thin Flowing Torch Brazing Alloy for Aluminum View Product Datasheet View Product SDSINTERNATIONAL CLASSIFICATIONSAWS A5.10 ER 4047EN/ISO 3677: B AL 88 SiDIN 8513: L AL Si 12FEATURES & APPLICATIONSApplications:General purpose outdoor use on repairing aluminum skids, platforms, loading docks, truck bodies, irrigation piping, fences and railings.Joining thick to thin sections requiring a combination of braze-welding and brazing techniques.Features:Extremely thin flowing alloy with excellent capillary action.Flux residue washes off easily with warm water. All Weld Metal Analysis (Typical Weight %)SiFeCuMgMnZnTiAl11-13.8.03.05.015.20.15Bal Typical Mechanical PropertiesUndiluted Weld Metal Maximum Value Up to:Tensile Strength up to 44,000 PSI (315 MPa)Bonding Temperature 800° – 1000°FBrazing InstructionsBrazing Techniques: Clean the surface and preheat heavy sections. For thin flowing, adjust the torch to 3X carburizing and preheat to a higher temperature. Once the piece is preheated simply allow some of the flux to melt off the rod. When the flux flows through the joint melt off some of the alloy and keep the torch moving constantly until the alloy flows throughout the joint.APPROXIMATE ELECTRODE PACKAGING & DIMENSIONSDiameter (mm)3/32 (2.4)1/8 (3.2)Length (mm)18″ (456)18″ (456)The ALUMA FLOW rods will be packaged in our new seamless aluminum pull ring moisture barrier can.
