TOKO AWS A5.10 ER5356 (AIMg5) Welding Wire

1. Standard & Classification:

• Conforms to AWS A5.10, classified as ER5356 (AIMg5).
• "ER" indicates suitability as an Electrode or Rod. "AIMg5" denotes an aluminum-magnesium alloy with ~5% Mg.

2. Chemical Composition:

• Primary Alloying Elements:
• Magnesium (Mg): 4.5–5.5% (enhances strength and corrosion resistance).
• Manganese (Mn): 0.05–0.20%.
• Chromium (Cr): 0.05–0.20%.
• Balance: Aluminum (Al), with trace impurities (Fe, Si, Zn) tightly controlled.

3. Mechanical Properties (As-Welded):

• Tensile Strength: ~38 ksi (262 MPa).
• Yield Strength: ~17 ksi (117 MPa).
• Elongation: ~20% (good ductility).
• Melting Point: ~600°C (typical for aluminum alloys).

4. Applications:

• Welds 5xxx series aluminum alloys (e.g., 5052, 5083, 5356).
• Common in marine, automotive, bicycle frames, and structural components due to excellent corrosion resistance and moderate strength.
• Suitable for MIG (GMAW) and TIG (GTAW) processes.

5. Shielding Gas & Welding Parameters:

• MIG: Argon or argon-helium mixtures.
• TIG: Argon, using AC or DCEN.
• Produces smooth welds with minimal spatter and resistance to hot cracking.

6. Manufacturer-Specific Features (TOKO):

• Likely optimized for consistent feedability and stable arc performance.
• Packaging may include moisture-resistant materials to prevent oxidation.

7. Available Sizes:

• Standard diameters: 0.8 mm, 1.0 mm, 1.2 mm (varies by application).
• Offered in spools or cut rods for TIG.

8. Limitations:

• Avoid use in high-temperature environments (>150°C), as Mg content may reduce corrosion resistance.
• Not ideal for 6xxx series base metals (use ER4043 instead).

9. Storage & Handling:

• Store in a dry, cool environment to prevent oxidation.
• Use sealed containers for prolonged storage.

Key Advantages:

✅ Excellent corrosion resistance in marine/salty environments.
✅ Good weldability with minimal post-weld cleanup.
✅ Versatile for both MIG and TIG processes.
