AK-ER1070 Pure Aluminum Welding Wire for TIG and MIG Welding.
A high-purity aluminum filler metal with over 99.7% aluminum content, suitable for welding pure aluminum and low-performance aluminum alloys in power and chemical industry applications.
Product Overview
AK-ER1070 is a pure aluminum welding wire containing more than 99.7% aluminum, formulated for use in argon arc welding (TIG or MIG) and oxygen-acetylene gas welding. It is designed for joining pure aluminum and aluminum alloys where high joint strength is not required.
The wire offers good weldability, excellent plasticity, toughness, and corrosion resistance, making it suitable for applications in the electric power and chemical industries. Its low strength is balanced by high ductility and ease of processing in various welding positions.
Application: Argon arc welding (MIG or TIG) and oxygen-acetylene gas welding are used to weld pure aluminum and aluminum alloys that do not require high joint performance as filling materials, and are widely used in aluminum equipment in the electric power and chemical industries.
Key Benefits
High Purity for Corrosion Resistance.
Excellent Plasticity and Toughness.
The wire delivers high elongation of 35 percent, ensuring good ductility and resistance to cracking during forming or thermal cycling.
Good Weldability in TIG and MIG Processes.
AK-ER1070 performs reliably in both TIG and MIG welding, producing smooth, stable arcs and consistent bead profiles with minimal spatter.
Suitable for Non-Critical Joints.
It is ideal for applications where joint performance does not require high strength, such as non-load-bearing structures and equipment components.
Where It Is Used
- Welding of pure aluminum and low-strength aluminum alloys.
- Fabrication and repair of aluminum equipment in the electric power industry.
- Construction and maintenance of chemical processing vessels and piping.
- Non-structural welding in aluminum structures requiring good formability and corrosion resistance.
Who It Is For
- Welding consumable distributors supplying aluminum filler metals for industrial applications.
- Fabricators working with pure aluminum in power and chemical sectors.
- Maintenance teams performing repairs on aluminum equipment where high strength is not required.
Problems It Solves
- Matching a filler metal with sufficient purity and corrosion resistance for service in chemical and power plant environments.
- Avoiding over-engineering joints with high-strength filler metals when only moderate performance is needed.
- Finding a consistent, certified aluminum wire that meets international standards without sourcing from multiple suppliers.

Use Guide
- Select wire diameter based on joint thickness and welding process; ensure consistent wire feed in MIG and stable arc control in TIG.
- Clean the base metal surface thoroughly to remove oil, oxide, and moisture before welding to prevent porosity and contamination.
- Use inert gas shielding (argon) for TIG and MIG processes to maintain weld quality and prevent oxidation.
- Store the wire in sealed packaging to prevent moisture absorption and contamination; re-clean if exposed to humid or dirty environments.
How It Compares
AK-ER1070 is a pure aluminum filler metal with over 99.7% aluminum, suitable for non-critical joints. It differs from higher-strength aluminum alloys like ER4043 or ER5356, which offer greater strength but lower ductility. ER1070 is not intended for high-load applications. It is also distinct from aluminum-magnesium alloys, which have higher strength but may require different welding parameters and post-weld treatment.
