OK Tigrod 18.22
OK Tigrod 18.22 are bare welding rods designed for aluminium alloys with more than 3 % Mg, offering high tensile strength. Small additions of Zr improve grain structure and reduce hot cracking.
Key Features
- Suitable for high‑strength aluminium alloys such as AlMg4.5Mn, AlMg5Mn, AlMg5Cr
- Contains Zr for finer grain structure and better crack resistance
- Works with shielding gases I1, I2, I3 (EN ISO 14175)
Specifications
- Alloy Type: Alloyed aluminium (Al + 6 % Mg + 0.8 % Mn + Ti + Zr)
- Yield Strength (As Welded): 160 MPa
- Tensile Strength (As Welded): 330 MPa
- Elongation: 25 %
- Charpy Impact (20 °C): 26 J
- Typical Composition (%): Mn 0.8, Si 0.06, Al 92.93, Cu 0.03, Ti 0.03, Zr 0.1, Mg 5.8
Applications
- Welding of high‑strength aluminium‑magnesium alloys
- Structural and marine aluminium components
- Projects requiring resistance to hot cracking
