ER2319 Aluminum Welding Wire

ER2319 Aluminum Welding Wire – Aerospace-Grade Al-Cu Filler Metal

As a Er2319 Aluminum Welding Wire.html manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Hangzhou Kunli Welding Materials Co., Ltd. is a high-technology manufacturer and supplier of ER2319 aluminum welding wire, engineered for the demanding requirements of aerospace, defense, and cryogenic applications. As a China-based factory with over 20 years of aluminum alloy wire production experience, we produce this Al-Cu series filler metal to AWS A5.10 / ASME SFA-5.10 standards, ensuring consistent chemistry, mechanical properties, and feedability for critical welded assemblies.

Our ER2319 wire is available in MIG, TIG, and drum formats, with diameters from 0.8 mm to 5.0 mm. We supply OEM/ODM customers worldwide, backed by monthly production capacity exceeding 200 MT and certifications including DB, CE, ABS, DNV, and CCS.

Product Overview and Applications

ER2319 is a copper-alloyed filler metal (5.8–6.8% Cu) designed for welding 2219 series aluminum alloys. It provides high tensile strength, excellent seawater corrosion resistance, good bending properties, and high fracture toughness. The alloy responds well to post-weld heat treatment, allowing restoration of mechanical properties in the heat-affected zone.

Typical applications include:

• Aerospace engineering: fuel tanks for launch vehicles, aircraft structural components
• Defense industry: armored vehicle plating, military hardware requiring 2219 alloy
• Cryogenic vessels: storage tanks for liquefied gases, performing reliably at extreme low temperatures
• High-temperature piping: industrial fluid transport systems exceeding standard aluminum limits

Technical Specifications and Compliance

Our ER2319 wire meets multiple international standards, including GB/T 10858 S Al 2319, DIN EN ISO 18273 S Al 2319 (AlCu6MnZrTi), and AWS/ASME SFA-5.10 ER2319. The chemical composition is tightly controlled to ensure consistent weld quality.

Mechanical Properties of Typical Welded Joints

The following table shows typical joint performance when welding common base alloys with ER2319. Actual results depend on welding procedure and base material condition.

Welding Process and Configuration Options

ER2319 is suitable for both Gas Metal Arc Welding (GMAW/MIG) and Gas Tungsten Arc Welding (GTAW/TIG). We supply wire in various packaging to match your production setup:

• MIG spools: 0.5–9 kg, ideal for robotic and semi-automatic welding
• TIG rods: 5–20 kg bundles, for manual precision welding
• Drums: 40–80 kg, for high-volume automated lines
• Coils: 8–15 kg, for continuous feed applications

For automated integration, our wire is precision-drawn with controlled surface finish to ensure consistent feedability in liners and contact tips, reducing downtime and weld defects.

Quality Control and Certifications

As a manufacturer, we implement strict quality control throughout production, from raw material inspection to final packaging. Our ER2319 wire has achieved international certifications including DB, CE, ABS, DNV, and CCS, confirming its suitability for marine, defense, and pressure vessel applications. We also collaborate with research institutions such as Beijing Nonferrous Metals Research Institute and Central South University to continuously improve product performance.

Storage and Handling Recommendations

Aluminum welding wire is susceptible to moisture absorption and oxidation. To maintain weld quality:

• Store in a dry environment with relative humidity below 60%.
• Keep in original moisture-proof packaging until use.
• If exposed to atmosphere for extended periods, store in a heated cabinet to prevent hydrogen-induced porosity.

Information We Use to Configure Your Solution

To prepare a precise quotation and recommend the right packaging and diameter, we need the following project details:

• Base material alloy and thickness (e.g., 2219-T87 plate)
• Welding process (MIG or TIG) and whether automated or manual
• Required diameter and packaging preference
• Annual or monthly consumption volume
• Any specific certification or documentation requirements

FAQs

What base materials is ER2319 designed to weld?

ER2319 is specifically formulated for welding 2219 series aluminum alloys, which are commonly used in aerospace and high-strength structural applications. It can also be used for other 2xxx series alloys with similar chemistry.

Can ER2319 be used for cryogenic applications?

Yes, ER2319 maintains excellent ductility and toughness at cryogenic temperatures, making it ideal for LNG storage tanks and other low-temperature vessels.

What shielding gas is recommended?

We recommend 100% argon or an argon/helium mixture to provide adequate protection for the molten weld pool and prevent porosity.

Does ER2319 require post-weld heat treatment?

ER2319 responds well to post-weld solution heat treatment and aging, which can restore mechanical properties in the heat-affected zone. The need for PWHT depends on the application and specified requirements.

What packaging options are available for automated welding lines?

For automated lines, we offer drums in 40–80 kg and spools in various sizes. Our wire is designed for consistent feedability, reducing downtime.
