HILCO ALUMINIL Si12

Aluminil Si12 is our special coated electrode developed for welding all types of aluminium castings and applications where good colour matching with base materials is important. Typical applications include repair welding, surfacing and construction welding: window frames, aluminium tubes, furniture, aluminium castings, engine blocks, and automotive parts. The electrode has a pure white coating specifically designed to reduce moisture pick-up. For thicker plate materials (≥15 mm) it is recommended to preheat at 150°C to 250°C before welding.
