Description
Böhler Union AlSi 5 (ER4043) Aluminium TIG Welding Rods
The Böhler Union AlSi 5 (often classified as AWS A5.10 ER4043) is a top-tier solid wire rod engineered for Gas Tungsten Arc Welding (GTAW) of aluminum alloys containing up to 2% alloying elements, or casting alloys with up to 7% silicon. This 5% silicon-aluminum wire provides outstanding fluidity, resulting in excellent wetting behavior and smooth bead appearances, which minimizes post-weld dressing and reduces the risk of burn-through on thinner materials.
