产品名称 ER5087
ALUMINUM WELDING WIRE (MIG & TIG)
ER5087 (AlMg4.5MnZr) is an aluminum-magnesium filler metal containing approx. 4.8% magnesium with zirconium grain refiner.
Key Features: Zirconium refines weld grains, superior solidification crack resistance vs ER5183 for highly restrained joints, outstanding low-temperature toughness, preferred for high-end marine structures.
Applicable Standards
AWS A5.10：ER5087（MIG）/ R5087（TIG）
EN ISO 18273：S Al 5087（AlMg4.5MnZr）
Standard Diameter & Packaging
• MIG wires: 0.8/0.9/1.0/1.2/1.6 mm, Standard spools: 0.45kg, 0.5kg, 1kg, 2kg,6 kg, 7 kg
• TIG rods: 1.6/2.0/2.4/3.2/4.0/5.0 mm, 1m fixed length, packed in5kg plastic tube and 5kg cardboard box.
Mechanical Properties of Deposited Metal
• Tensile Strength: 270–290 MPa
• Yield Strength: 130–150 MPa
• Elongation (A5): 16%–21%
• Melting Range: 580–645℃
Shielding Gas (MIG + TIG)
• Preferred: 100% pure Ar. Ar+He mixture for thick plates with deep penetration.
• Flow rate: MIG 18–25 L/min, TIG 12–18 L/min·
• Wind shielding is mandatory during welding.
Key Advantages
• Zirconium refines weld structure; better hot crack resistance vs ER5183 for highly restrained joints
• High strength & outstanding low-temperature toughness for low-temp tanks and marine constructions
• Excellent seawater & chloride resistance, preferred for premium marine projects
• Uniform white finish after anodizing, suitable for aesthetic structural components
• Stable arc, low spatter, smooth feeding; works for MIG and TIG welding
• Outperforms ER5356 in exfoliation and stress corrosion resistance
Recommended Base Metals
✅ Recommended 5083, 5086, 5456 high-magnesium 5xxx Al-Mg alloys
✅ Dissimilar welding: 5083/5086 ↔ 6061/6082 Al-Mg-Si alloys
⚠️ Caution Not suitable for 5454 (ER5554 preferred); avoid cast aluminum
❌ Prohibited for 4xxx Al-Si alloys (No mixing with ER4043/ER4047 matched materials)
Important Note: Risk increases for continuous service over 120℃; use ER5554 for high-temperature parts.
