Item Details

  • AlcoTec AlTIGweld ER4643 1/8" Dia X 36" Aluminum TIG Welding Rod comes in a 10 lb box and renders magnificent corrosion resistance in the weld zone as well as heat affected regions. Welding rod is a perfect choice for brazing type applications on thin sections where dilution ratios are low. Welding rod has same weld cracking characteristics flow pre-cleaning weldability and machine settings as of 4043 alloy. Welding rod is ideally used for welding heavy sections of certain aluminum alloys when multiple weld passes are required and dilution of the base metal into the puddle is negligible.


  • Alloy 4643 is very similar in weldability to 4043
  • Heat treatable
  • Principle alloying elements: Silicon magnesium
  • The weld cracking characteristics flow pre-cleaning and machine settings are the same for this alloy as 4043
  • The corrosion resistance is very good and equals or exceeds alloy 4043 in the weld zone and heat affected regions
