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

Zhejiang Yuguang Aluminum Co., Ltd. produces an aluminum alloy welding wire formulated to match 2219 alloy grade requirements, positioned for structural welding where elevated temperature performance and stress corrosion resistance are critical. The wire carries a harbor trust tier with imported supplier status, though the listing shows zero response rate and no logged average response hours. It is compatible with both MIG and TIG processes, with the source noting particular suitability for aerospace, automotive, and marine fabrication environments where joint integrity under load matters.

The 2219 alloy family is an Al-Cu-Mn system with nominal 6.3% copper content, offering weldability superior to many high-strength 2xxx series variants due to its controlled manganese addition. Typical as-welded tensile strength for 2219 filler falls around 310-345 MPa, with post-weld heat treatment capable of raising values toward parent metal levels of 380-420 MPa. Silicon content in this grade is typically held below 0.2% to preserve fracture toughness, a specification buyers should confirm via mill test certificate. The wire is supplied with ISO and SGS certifications mentioned in the source, though buyers should verify current certificate validity and scope directly with the supplier.

Target applications include pressure vessel repair, cryogenic tank construction, and airframe component welding where 2219-T87 or similar tempers are specified. Importers should note that Wuyi, Zhejiang sits within China's mature aluminum processing corridor, with access to Ningbo and Shanghai ports for export shipment. The listing references L/C and T/T payment terms without specifying minimum order quantities, advance deposit percentages, or whether pricing is quoted on ex-works, FOB, or CIF basis. Buyers are advised to request full mechanical test data, including all-weld-metal tensile and Charpy V-notch results, before finalizing specifications.

Zhejiang Yuguang Aluminum Co., Ltd. is located at 22 Hehua Road, Economic and Development Zone, Wuyi, Zhejiang Province, postal code 321200. The company holds imported supplier tier status on its marketplace profile, with harbor designation indicating a foundational verification level. The response rate shows 0.00% with zero average response hours, which suggests either a new listing, dormant account, or data collection gap rather than necessarily indicating non-operation. The physical address places the firm in Wuyi County, part of Jinhua City's jurisdiction, within one of China's denser aluminum product manufacturing regions with established supply chain infrastructure.

The listing does not disclose production capacity, number of employees, year of establishment, revenue figures, or named client references. No specific factory audit certifications beyond the mentioned ISO and SGS are detailed, and the scope of these certifications (whether quality management, product, or process) is unstated. Buyers should conduct independent verification of company registration, export license status, and manufacturing specialization, whether the firm produces wire from cast billet or sources redraw stock externally. The absence of response data means direct enquiry is essential to assess commercial viability.
