HILCO ALUMINIL Si5
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.
Best features
+ Universal Compatibility: Aluminil Si5 welds, repairs, and joins various aluminum alloys, with ease. (Except AlMg castings)
+ Moisture-Resistant: Its pure white coating is specifically designed to reduce moisture pick-up
+ Versatile Use: Ideal for both cast and forged aluminum-silicon alloys, plus dissimilar aluminum alloy combinations with up to 7% Si content.
+ Efficient Welding: Preheat for thicker materials (≥15 mm) for superior results and efficiency
