Import Aluminum Alloy Welding Wire Er4047 — Buy in Bulk from Supplier in China

The ER4047 aluminum alloy welding wire from Zhejiang Yuguang Aluminum Co., Ltd. is a silicon-rich filler metal containing approximately 12% silicon, which lowers the melting point and increases fluidity for smoother weld pools. This composition is specifically formulated for welding heat-treatable aluminum base alloys, particularly the 6xxx series, where its high silicon content improves wetting and reduces hot cracking in the weld zone.

Supplied as a spool of continuous wire, ER4047 is compatible with MIG and TIG welding processes, offering stable arc characteristics and minimal spatter. The wire meets typical industry standards for diameter tolerances of ±0.002 inches and tensile strengths exceeding 23,000 psi in as-welded condition. Its corrosion resistance is standard for aluminum-silicon alloys, though anodizing or coating may be required for harsh environments. The wire is typically packaged in vacuum-sealed plastic or moisture-barrier bags to prevent oxidation.

This wire is widely used in automotive, aerospace, and structural fabrication where joining dissimilar aluminum alloys or repairing castings is required. Buyers in these sectors often source ER4047 for its ability to bridge gaps in components with varying thermal expansion rates. Trade terms for this supplier’s stock include bulk spool sizes of 15 kg or 25 kg, with lead times and Incoterms to be confirmed directly with Zhejiang Yuguang Aluminum Co., Ltd.
