Aluminum Welding Rods - 5% Silicon (Si)
Aluminium Welding Wire – 5% Silicon (Si)
Our reliable aluminium welding wire with 5% silicon is the most widely used filler material for gas welding a broad spectrum of aluminium alloys. The silicon content is added to give the melt fantastic fluidity and drastically reduce the risk of solidification cracking during cooling.
This rod is the natural choice for those seeking an easy-to-handle, highly fluid melt, especially when repairing castings or joining sheets where tightness and a beautiful finish are top priorities.
Features and Benefits:
- Exceptional Fluidity: The high silicon content lowers the melting point and makes the weld pool extremely fluid, making it easy to create smooth and clean transitions.
- Crack Resistance: Silicon minimizes the material's shrinkage during solidification, which drastically reduces the risk of hot cracking in the weld.
- Leak-Proof Joints: Very good ability to penetrate and seal, making it ideal for liquid containers, pump housings, and pipes.
- Easy to Work With: A forgiving welding rod that is easy to handle even during more complex repairs.
Important for a Successful Result:
For gas welding in aluminium, the use of our aluminium welding flux is required. This is essential to break down the tough oxide layer and allow the silicon alloy to flow out and fuse perfectly with the base material.
Specifications & Sizes:
This wire is stocked in a versatile dimension that covers most needs in aluminium gas welding:
- Dimension: 3.2 mm diameter.
- Length: 1000 mm.
- Packaging: Choose between 0.5 kg or 1.0 kg.
- Alloy: Aluminium with 5% Silicon (Si).
- Welding method: Gas welding (Oxy-Acetylene).
Pro Tip: Heat the end of the wire and dip it into the aluminium welding flux. By briefly heating the flux stuck to the wire, you can make it run down along the rod. This allows you to weld longer sections with a steady flow of flux without interruption.
