ER5754 Aluminum Welding Wire

ER5754 Aluminum Welding Wire

As a leading ER5754 Aluminum Welding Wire manufacturer and supplier, Hangzhou Kunli Welding Materials Co., Ltd. produces this Al-Mg3 filler metal for demanding structural applications. With over 20 years of aluminum alloy wire production experience, we deliver ER5754 wire that meets AWS A5.10 and ISO 18273 standards, backed by certifications including DB, CE, ABS, DNV, and CCS. Our monthly capacity exceeds 200 metric tons, and we export to over 30 countries, serving industries such as shipbuilding, automotive, and chemical processing.

ER5754 contains approximately 3% magnesium, offering medium strength and excellent seawater corrosion resistance. It is specifically designed for GMAW and GTAW welding of 5xxx and 6xxx series aluminum alloys, including 5083, 5086, 6061, and 6063. Our precision shaving process removes surface oxides, ensuring a stable arc, reduced porosity, and smooth wire feeding—critical for high-productivity operations.

Product Range and Configurations

We supply ER5754 in various diameters and packaging to match your welding process and production scale. Our standard options include:

For automated welding lines, we recommend 1.2mm or 1.6mm MIG wire on 5kg or 7kg spools for optimal feed stability. TIG rods are cut to standard lengths and straightened for precise manual control.

Applications and Material Fit

ER5754 is engineered for environments where corrosion resistance and weld strength are non-negotiable. Typical applications include:

• Shipbuilding and Marine Engineering: Hulls, decks, and tanks fabricated from AlMg3 alloys, exposed to saltwater.
• Automotive Industry: Body panels, structural supports, and pressure vessels requiring moderate strength and weight reduction.
• Chemical Processing Plants: Storage tanks and piping for corrosive chemicals, where intergranular corrosion resistance is critical.
• General Fabrication: Railway components, architectural structures, and welded furniture.

The wire's anodic oxidation compatibility makes it ideal for post-weld anodizing, as the weld seam color matches the base material—an advantage over silicon-based fillers like ER4043.

Critical Specifications and Quality Control

Our ER5754 wire is produced with tight chemical composition control and mechanical property verification. Key specifications include:

• Chemical Composition: Mg 2.6-3.6%, Mn ≤0.5%, Cr ≤0.3%, Si ≤0.4%, Fe ≤0.4%, Cu ≤0.1%, Zn ≤0.2%, Ti ≤0.15%, Be ≤0.0003%, others each ≤0.05%, total ≤0.15%, balance Al.
• Melting Range: Approximately 580°C - 640°C (1055°F - 1195°F).
• Density: 2.66 g/cm³.
• Typical Weld Joint Mechanical Properties: Tensile Strength (Rm) ≥200 MPa, Yield Strength (Rp0.2) ≥80 MPa, Elongation (A) ≥20%.

We operate a comprehensive testing laboratory equipped with SHIMADZU PDA 5500-Optical Emission Spectrograph, LEICA DM2550 Metallographic Microscope, Tension Tester, and OTC A-V6 Welding Robot System. Every production lot is tested for chemical composition, mechanical properties, and welding performance to ensure compliance with AWS A5.10 and ISO 18273.

Welding Parameters and Best Practices

To achieve optimal results with ER5754, follow these guidelines:

For MIG welding of 3-8mm thick sections, typical parameters include 19-23V, 6-8 m/min wire feed speed, and 20-25 CFH gas flow rate. Adjust based on joint configuration and base material thickness.

Storage and Handling

ER5754 is sensitive to humidity. Store in a dry environment with relative humidity below 60%. Keep the wire in its original moisture-proof packaging until use. If exposed to air for extended periods, store in a heated cabinet at 10-15°C above ambient temperature to prevent condensation. Proper storage prevents porosity and maintains arc stability.

Information We Use to Configure Your Solution

To prepare a precise quotation and configuration, we need the following project details:

• Base material alloy and thickness
• Welding process (MIG, TIG, or automated)
• Required wire diameter and packaging type
• Production volume and monthly consumption
• Application environment (e.g., marine, chemical, automotive)
• Any specific standards or certifications required

Our engineering team will recommend the optimal wire grade, diameter, and packaging to match your welding equipment and production targets. We also provide technical support for parameter optimization and troubleshooting.

FAQs

What is the difference between ER5754 and ER5356?

ER5754 has lower magnesium content (2.6-3.6%) compared to ER5356 (4.5-5.5%), resulting in slightly lower strength but better ductility and corrosion resistance in seawater. ER5754 is often preferred for marine and chemical applications where stress corrosion cracking is a concern.

Can ER5754 be used for welding 6061 aluminum?

Yes, ER5754 is recommended for welding 6061 and other 6xxx series alloys, especially when post-weld anodizing is required. It provides good color match and corrosion resistance, though for higher strength requirements, ER5356 or ER5183 may be considered.

What certifications does your ER5754 wire hold?

Our ER5754 wire is certified to DB, CE, ABS, DNV, and CCS standards. We also comply with ISO 9001, ISO 14000, and ISO 18001 for quality and environmental management.

Do you offer custom packaging or labeling?

Yes, we can customize packaging, spool sizes, and labeling according to your specifications. For OEM/ODM projects, we can also produce wire with your brand name.

What is your typical lead time for ER5754 orders?

Lead time depends on order quantity and packaging. For standard spools, we typically ship within 2-3 weeks after deposit. For large orders or custom configurations, please contact us for a specific timeline.
