KOVET AlSi 12 can be used for joint and repair welding on aluminum wrought and cast alloys when higher strength is required. In order to avoid shrinkage cracks, the complete cast aluminum piece should usually be pre heated accordingly. The electrode has good welding properties and is suitable for welding in all positions. The core-wire consists of an aluminum alloy with approximately 12% silicon.
