产品名称 ER1050
ALUMINUM WELDING WIRE (MIG & TIG)
ER1050 (Al99.5) is pure aluminum filler wire for welding 1xxx series pure aluminum materials.
Key Features: Ultra-low impurity content, excellent electrical conductivity and high corrosion resistance. Caution: Low mechanical strength, not for load-bearing structural parts; unsuitable for 5xxx/6xxx dissimilar high-strength welding.
Applicable Standards
AWS A5.10 ER1050（MIG）/ R1050（TIG）
EN ISO 18273：S Al 1050（Al99.5）
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: 2.0/2.4/3.2/4.0/5.0 mm, 1m fixed length, packed in5kg plastic tube and 5kg cardboard box.

Shielding Gas (MIG + TIG)
• Preferred shielding gas: 100% pure Ar. Ar+He mixture is available for thick plates requiring deep penetration.
• Flow rate: MIG 18–25 L/min, TIG 12–18 L/min.
Mechanical Properties of Deposited Metal
• Tensile Strength: 70–95 MPa
• Yield Strength: 25–40 MPa
• Elongation (A5): 30%–40%
• Melting Range: 645–660℃
Key Advantages
• High purity aluminum matching wire for 1050, 1060, 1070 pure aluminum sheets and strips
• Outstanding electrical conductivity, ideal for conductive busbars and electrical components
• Superior resistance to chemical corrosion, fit for chemical equipment and anti-corrosion liners
• Uniform silver-white appearance after anodizing, no obvious color difference
• Stable arc, minimal spatter, ultra-smooth weld surface
• Compatible with MIG and TIG, perfect for thin pure aluminum plate welding
Recommended Base Metals
✅ Recommended: 1050, 1060, 1070, 1100 pure aluminum alloys
✅ Dissimilar welding: Various 1xxx pure aluminum combinations
⚠️ Caution: Low tensile strength, cannot be used for stressed load-bearing structures
❌ Do not weld 5xxx high-magnesium or 6xxx heat-treatable aluminum alloys, obvious strength drop and poor corrosion resistance
Applications
• Conductive aluminum busbars, electrical cabinet conductive parts
• Chemical anti-corrosion equipment, aluminum lining tanks
• Thin pure aluminum decorative panels, heat dissipation shells
• Food processing aluminum containers and storage vessels
• Light-duty non-load aluminum enclosures and ventilation ducts
