产品名称 ER1100
ALUMINUM WELDING WIRE
ER1100 (Al99.0) is commercial pure aluminum filler wire for welding general 1xxx pure aluminum materials.
Key Features: Stable pure aluminum composition, good electrical conductivity and outstanding general corrosion resistance. Caution: Low mechanical strength, not for load-bearing structural parts; not suitable for welding 5xxx/6xxx series aluminum alloys.
Applicable Standards
AWS A5.10 ER1100（MIG）/ R1100（TIG）
EN ISO 18273：S Al 1100（Al99.0）
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.
Welding Polarity
• MIG (GMAW)：DCEP
• TIG (GTAW)：AC
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: 70–98 MPa
• Yield Strength: 28–42 MPa
• Elongation (A5): 28%–38%
• Melting Range: 643–658℃
Key Advantages
• Good electrical conductivity, applicable for common conductive aluminum parts
• Excellent atmospheric and mild chemical corrosion resistance
• Uniform silver-white finish after anodizing with slight color difference
• Stable arc, low spatter and smooth weld bead
• Compatible with MIG and TIG, ideal for thin and medium pure aluminum sheets
Recommended Base Metals
✅ Recommended: 1100, 1050, 1060, 1070 commercial pure aluminum alloys ✅ Dissimilar welding: Various combinations of 1xxx pure aluminum materials
⚠️ Caution: Low tensile strength, cannot be used for stressed load-bearing structures
❌ Do not weld 5xxx magnesium-containing or 6xxx heat-treatable aluminum alloys, which will cause strength decline and poor corrosion resistance
Applications
• General conductive aluminum busbars, electrical cabinet conductive accessories
• Atmospheric corrosion-resistant equipment, ventilation aluminum ducts
• Food-grade aluminum containers and light storage tanks
• Thin aluminum decorative panels and heat dissipation shells
• General anti-corrosion lining and non-load aluminum housings
Common Welding Problem & Solutions
· Weld Porosity
Cause: Insufficient oxide cleaning, wet shielding gas, wind interference.
