5kg - 2.4mm ER4047 Aluminium TIG Filler Wire Rods 

Hampdon Industrial supplies Premium quality ER4047 Aluminium TIG filler rod. ER4047 is commonly known for its low melting point and narrow freezing range. It has a high silicon content compared to ER4043 which allows for reduced shrinkage in the weld due to a higher level of fluidity. ER4047 offers a bright and clean weld. This alloy may be able to be used in high-temperature situations as its additional silicon content reduces hot cracking and increases the weld's shear strength.

For Castings like cylinder heads, a high silicon rod-like 4047 is often chosen because of its lower melting temperature and fluidity and less tendency to get porosity or cracks. Our high purity fillers have sensational flow characteristics and produce exceptional welds that are free of cracks, Fusion defects, and other problems to which inferior wires are prone.

Each rod is individually stamped or laser engraved with its grade identification marking. Beware of cheap, inferior products which are nonidentifiable once removed from their packet. All our TIG wire is individually packed, labeled, and transported in a sturdy tube or box, ensuring your wire stays in excellent condition during transport. All filler wire and electrodes that Hampdon industrial stock is and premium quality and can be supplied with a certificate of conformance which is essential for manufacturing data reports. (MDR) Specifications


  • Grade – 4047
  • Industrial Quality
  • Batch number certificate of conformance supplied
  • Suitable for the repair of Cylinder heads
  • Lower melting point of only 632 degrees celsius, making it possible for aluminum brazing applications in addition to welding
  • Increased fluidity(wetting action) and reduced shrinkage
  • Excellent for welding thinner materials that are required to have leakproof joints
  • Attractive bright weld appearance
  • It May be used in applications of sustained elevated temperatures, for example, aluminum heat exchangers
  • Like the 4043 filler rod, 4047 should not be used if you are considering the best color match after post-weld anodizing, as this filler alloy will typically turn dark grey after the anodizing process because of the silicone content.
