Description
Siftrode Aluminium Electrode Alu SI12 MMA (Stick) – 3.2 mm x 0.5 Kg
The Siftrode Aluminium Electrode Alu SI12 is specifically designed for rapidly joining cast aluminium alloys. It is highly recommended for mending broken gear parts or other casting components. This electrode is not only ideal for joining but also for cladding or rebuilding parts. It offers excellent weldability, ensuring good penetration and a porosity-free deposit. One of its unique features is the self-lifting slag, coupled with an improved coating that protects against moisture pick-up, ensuring the longevity and quality of the weld.
Features & Benefits:
- Rapid Joining: Specifically designed for quickly joining cast aluminium alloys.
- Versatility: Perfect for mending broken gear parts or other casting components.
- Rebuilding Capabilities: Ideal for cladding or rebuilding parts to extend their lifespan.
- Superior Weldability: Ensures good penetration and a porosity-free deposit for a strong bond.
- Self-Lifting Slag: Unique feature that ensures easy cleanup post-welding.
- Moisture Protection: Improved coating protects against moisture pick-up, enhancing the electrode’s performance.
