Aluminil Si5 is our special coated aluminium electrode for welding, repairing and surfacing forged and cast aluminium-silicon alloys and joining dissimilar aluminium alloys with max.
7% Si content.
The easy flowing characteristics make the electrode suitable for welding all aluminium castings (except AlMg castings).
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.
