SIFMIG 4043 – Aluminium MIG Wire – 1.2 mm x 0.5 Kg
An Aluminium alloy with 5% silicon giving excellent flow characteristics and penetration. Suitable for welding:
- Cast and wrought alloys 6063 (H9), 6061 (H20) and 6082 (H30).
- Weld will discolour if anodised.
Ensure that the parent metal surface is cleaned and fully degreased prior to welding. Clean joints with a stainless steel brush.
Typical Mechanical Properties
|Ult Tensile Strength||120 N/mm²|
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.
|Melting Point (°C)||635|
|Shielding Gas||Argon, Argon/Helium|
