Aluminium Tig Welding Wire

What is the difference between 4043 & 5356 TIG filler rods?

4043 (Silicon alloy)

• 4043 aluminium alloy rods have a 5 % silicon content offering excellent fluidity, a superior wetting action ideal for intricate welds and minimizing the risk of cracking.
• Produces aesthetically pleasing, shiny weld beads with minimal porosity.
• Suitable for welding heat treatable base alloys, as well as cast and wrought aluminium.
• High silicon content reduces cracking.

5356 (Magnesium alloy)

• 5356 filler wire contains 5 % magnesium & offers exceptional corrosion resistance.
• Offers superior tensile strength for high stress applications
• Provides excellent ductility, allowing for easier shaping and forming post-weld.
• Ideal for structural applications & projects where durability and strength are crucial.
