Description
Sifmig 5556 Aluminium MIG Welding Wire – 1.2 mm x 6.5 Kg
Sifmig 5556 Aluminium MIG Welding Wire is a precision-crafted aluminium alloy wire, designed with a specific composition of 5.3% Magnesium and 0.8% Manganese. This unique blend ensures optimal weld strength. Notably, this wire produces a more robust weld metal compared to the standard 5% Mg 5356 alloy. It’s primarily intended for welding the 5083 (N8) alloy, a material extensively used in structural applications, and is especially suitable for military projects where maintaining full strength is paramount.
Key Features:
- Enriched with 5.3% Magnesium and 0.8% Manganese for enhanced weld strength.
- Offers superior strength over the 5% Mg 5356 alloy.
- Precision diameter of 1.2mm ensures consistent welding performance.
- Ideal for welding the widely-used 5083 (N8) alloy.
Common Applications:
Sifmig 5556 Aluminium MIG Welding Wire is versatile and is primarily used for:
- Welding the 5083 (N8) alloy, a popular choice in structural applications.
- Military projects where full strength retention is crucial.
Welding Positions
Ensure that the parent metal surface is cleaned and fully degreased prior to welding. Clean joints with a stainless steel brush.
