AK-ER80S-G Low Fuming Bronze Welding Wire for Brass, Copper, Steel and Cast Iron.
A bronze welding wire designed for low fuming operation, suitable for joining brass, copper, steel and cast iron with consistent mechanical properties and clean welds.
Product Overview
AK-ER80S-G is a low fuming bronze welding wire used for welding brass, copper, steel and cast iron. It is formulated for braze welding and fusion welding applications where clean fumes and good wetting are required.
The wire meets EN ISO 16834-A: G Z Mn3Ni1 Cu*, AWS A5.28 ER80S-G, and GB/T 8110 ER55-G standards. Its chemical composition includes 0.08% C, 0.54% Si, 1.64% Mn, 0.41% Cr, 0.006% S, and 0.012% P, which supports good fluidity and mechanical strength in the weld deposit.
Deposited metal properties include tensile strength of 665 MPa, yield stress of 585 MPa, elongation of 24.5%, and impact energy of 113 J at minus 40 degrees C, ensuring performance in demanding service conditions.
Application: Used to weld brass, copper, steel and cast iron products.
Key Benefits
Low Fuming Operation
The wire produces minimal fumes during welding, improving working conditions in enclosed or poorly ventilated areas.
Good Wetting on Diverse Materials.
Suitable for joining brass, copper, steel and cast iron, providing strong, reliable bonds without requiring high preheat or complex joint preparation.
High Impact Toughness at Low Temperature.
The deposited metal achieves 113 J impact energy at minus 40 degrees C, making it suitable for service in cold environments.
Consistent Mechanical Properties
Tensile strength of 665 MPa, yield stress of 585 MPa, and elongation of 24.5% ensure reliable performance under mechanical stress.
Where It Is Used
- Welding of brass components in plumbing and automotive fittings.
- Braze welding of copper and steel in heat exchangers and electrical connections.
- Repair and joining of cast iron parts in machinery and engine components.
- General-purpose fusion welding on dissimilar metals where low fuming is required.
Who It Is For
- Welding consumable distributors supplying bronze wires for industrial and repair applications.
- Fabricators working with brass, copper and cast iron in HVAC, marine and automotive sectors.
- Maintenance teams performing repairs on cast iron and steel components in harsh environments.
Problems It Solves
- Difficulty in joining brass and copper with high fume levels and poor wetting using standard filler metals.
- Lack of consistent mechanical properties in braze welds on dissimilar metals.
- Inadequate low-temperature impact performance in welds exposed to cold service conditions.

Use Guide
- Select wire diameter based on joint thickness and welding position: 0.8 mm for thin sections, 1.0 mm for medium, 1.2 mm for heavier sections.
- Use flat or horizontal welding with current range 50-180 A for 0.8 mm, 80-250 A for 1.0 mm, and 100-360 A for 1.2 mm.
- For vertical or overhead positions, reduce current: 50-100 A for 0.8 mm, 70-160 A for 1.0 mm, and 80-220 A for 1.2 mm.
- Clean joint surfaces of oil, rust, paint and moisture before welding to ensure good fusion and avoid porosity.
- Store wire in sealed packaging to prevent moisture absorption; re-dry if exposed to humid conditions before use.
How It Compares
AK-ER80S-G is a bronze wire designed for low fuming and good wetting on brass, copper, steel and cast iron. It differs from standard mild steel wires like ER70S-6 in composition and application, as it is not intended for structural steel welding. Compared to silver-based brazing rods, AK-ER80S-G offers higher strength and lower cost, though with lower ductility. It is not suitable for high-strength structural joints where full fusion and high toughness are required.
