Description

SIFMIG 4043 – Aluminium MIG Wire – 1 mm x 2 Kg

SIFMIG 4043 is an aluminium MIG wire alloyed with 5% silicon. This unique composition offers excellent flow characteristics and penetration. The wire is precision layer-wound, ensuring uninterrupted feeding, making it ideal for gas-shielded MIG welding on both semi-automated and fully-automated systems. It’s particularly suitable for welding duralumin, certain cast and wrought alloys, and other 4 series aluminium. However, it’s worth noting that the resulting weld will discolour if anodised.

Features & Benefits:

  • Silicon Enriched: Contains 5% silicon, enhancing flow characteristics and penetration.
  • Precision Layer Wound: Ensures consistent and uninterrupted feeding during the welding process.
  • Versatility: Suitable for welding a range of aluminium materials, including duralumin and specific alloys.
  • High Penetration: Offers excellent penetration for a stronger weld.
  • Discolouration Warning: The weld may discolour if subjected to anodising.

Common Applications:

  • Welding duralumin.
  • Suitable for welding cast and wrought alloys like 6063 (H9), 6061 (H20), and 6082 (H30).
  • Welding other 4 series aluminium materials.

Material To Be Welded

Suitable for welding duralumin, cast and wrought alloys 6063 (H9), 6061 (H20) and 6082(H30), as well as other 4 series aluminium. The resulting weld will discolour if anodised.

Pre-heating up to 120 degC may be necessary, subject to material size and thickness. Wire brushing between passes is recommended, to remove build up of surface oxides.

Ensure that the parent metal surface is cleaned and fully degreased prior to welding. Clean joints with a stainless steel brush.
