Our product range covers the 5xxx series (Al-Mg), 4xxx series (Al-Si), and other alloys, available in various diameters and packaging to meet MIG, TIG, and automated welding requirements. With a monthly capacity exceeding 200 MT and exports to over 30 countries, we supply both standard and customized solutions.

Product Range and Application Fit

We offer a comprehensive selection of aluminum alloy welding wires, each designed for specific base materials and service conditions. The table below summarizes our key products and their typical applications.

For detailed specifications of each alloy, please refer to our Aluminum Welding Wire range. We also supply specialty alloys like ER5087, ER5554, ER5556, ER1100, ER2319, and ER4943 for specific requirements.

Critical Specifications and Quality Control

Our wires are manufactured with precise diameter control (±0.01mm) and a shaved surface finish to ensure stable arc and smooth feeding. The chemical composition meets AWS A5.10 and ISO 18273 standards, with tight control of impurities. Each batch is tested in our laboratory using advanced equipment like SHIMADZU PDA-5500 optical emission spectrograph and OTC welding robot for performance verification.

• Diameter range: 0.8mm to 1.6mm (standard spools D200, D300)
• Surface oxide layer less than 30 angstroms, hydrogen content below 0.15 ml/100g
• Certifications: DB, CE, ABS, DNV, CCS
• Quality management: ISO9001, ISO14000, ISO18001

Configuration and Customization

We offer wires in various packaging: spools, coils, and straight rods for TIG. Custom diameters, tempers, and packaging are available upon request. Our R&D team can develop alloys based on your drawings or samples, ensuring the filler metal matches your base material and welding process.

Installation and Welding Considerations

Proper handling is essential for aluminum welding. We provide guidelines for storage (humidity below 60%, temperature 15-30°C) and feeder setup (U-groove rolls, Teflon liners). For MIG welding, use 100% argon or argon-helium mixtures; for TIG, maintain clean surfaces and proper gas flow. Our technical team can assist with parameter selection for your specific application.

Quality Assurance and Acceptance

Every spool is subject to chemical analysis, mechanical testing, and welding performance checks. We provide mill certificates and test reports upon request. Our wires have been qualified by major classification societies, and we are a qualified supplier to companies like China CRRC and Maersk, replacing imported products.

Maintenance and Support

We offer ongoing technical support, including troubleshooting guides for common issues like porosity and wire feeding problems. Our engineers are available for on-site assistance if needed. Spare parts for feeders and liners are available, and we can provide training for your welding team.

Information We Use to Configure Your Solution

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

• Base material alloy and thickness
• Welding process (MIG, TIG, automated)
• Required wire diameter and packaging type
• Production volume and delivery schedule
• Applicable standards or certifications
• Any special surface or composition requirements

Frequently Asked Questions

What is the difference between ER5154 and ER5356?

ER5154 has lower magnesium content (3.1-3.9%) compared to ER5356 (4.5-5.5%), resulting in slightly lower strength but better ductility. ER5356 offers higher strength and is often preferred for structural applications, while ER5154 is suitable for marine and pressure vessel use where corrosion resistance is critical.

Can you provide custom diameters or packaging?

Yes, we can customize wire diameters and packaging (spool sizes, coil weights, etc.) based on your production needs. Our R&D team can also adjust alloy composition for specific requirements.

How do you ensure consistent quality across batches?

We maintain strict process control and test every batch in our lab. Our quality system is certified to ISO9001, and we have received approvals from ABS, DNV, and CCS, ensuring traceability and reliability.

What is your typical lead time for orders?

Lead time depends on order quantity and customization. For standard products, we typically ship within 2-3 weeks after deposit. For custom alloys, please contact us for a specific timeline.

Do you provide technical support for welding issues?

Yes, our welding engineers can provide troubleshooting advice and on-site support if needed. We also offer documentation and training materials to help your team achieve optimal results.
