4047 filler metal common applications are for thin sections where the higher fluidity and lower shrinkage rate are important for distortion control. 4047 is also used in applications where excellent wetting action for joint sealing of pressurized fluids and gases is required. Features/Benefits: Low melting temperature/high fluidity. Excellent wetting action for joint sealing applications. Low welding smut and discoloration. Very low ductility, formability, and toughness. Moderate electrical conductivity and thermal conductivity. Excellent corrosion resistance. Very lowest shrinkage rate/reduced distortion. Low hot cracking sensitivity in most applications.
