Import 2uul 0.3/0.6mm Lead-Free Welding Wire — Buy in wholesale FOB from Supplier in China

The 2UUL lead-free welding wire is a flux-cored solder wire designed for precision electronics soldering, available in two diameters: 0.3 mm and 0.6 mm. Each spool contains 100 metres of wire with a net weight of 50 grams, giving a linear density that suits fine-pitch component work and general PCB assembly respectively. The alloy carries a 183 °C melting point, which aligns with common Sn-Ag-Cu (SAC) or Sn-Cu lead-free formulations rather than traditional 183 °C eutectic tin-lead, though buyers should confirm the exact alloy composition with the supplier. The wire is marketed as non-toxic, odourless, and low-smoke during operation, targeting workshops where operator comfort and environmental compliance matter.

The conductor core is described as high-purity tin-based material with stated high electrical and thermal conductivity. In lead-free soldering, typical SAC305 alloy contains 3.0% silver, 0.5% copper, and balance tin, with a melting range of 217-220 °C, so the 183 °C figure may refer to a specific low-melting lead-free variant or the flux activation temperature rather than the alloy liquidus. The 0.3 mm diameter suits micro-soldering of SMD components, fine-pitch ICs, and mobile device repair, while 0.6 mm handles through-hole components, larger joints, and faster feed rates in automated or manual soldering. Standard industry packaging for such wire is plastic spools or vacuum-sealed pouches to prevent oxidation; the 50 g spool size is typical for repair technicians and small-batch manufacturers.

This product serves electronics repair shops, mobile device refurbishment centres, PCB assembly houses, and educational institutions teaching surface-mount technology. The lead-free formulation meets RoHS directives for European and North American markets, though buyers should request formal alloy certification and test reports for compliance documentation. When sourcing from Shenzhen Weikexiu Technology Co., Ltd., confirm the exact alloy specification, flux core percentage, shelf life, and recommended storage conditions, as these determine wetting performance and joint reliability. The supplier's location in Shenzhen's Longgang District places them within China's principal electronics manufacturing corridor, with access to component supply chains and logistics hubs for both domestic and export shipment.

Shenzhen Weikexiu Technology Co., Ltd. operates from Juguang E-Commerce Industrial Park, Building 8, No.9 Qilin Road, Bantian Street, Longgang District, Shenzhen, 518116, China. The supplier holds a harbor trust tier, which represents a baseline verification status on the platform. The response rate is recorded at 0.00% with an average response time of 0 hours, indicating that no response data has been accumulated or the supplier has not yet engaged with buyer enquiries through the platform's messaging system. The listing presents itself as a product-specific offering with no additional company history, workforce figures, revenue data, or client references provided.

The company's location in Longgang District positions it within one of Shenzhen's established manufacturing and logistics zones, with proximity to the Shenzhen-Hong Kong border and major shipping ports. The industrial park address suggests operation within a dedicated e-commerce or light-manufacturing facility rather than a standalone factory complex. Buyers should note that the listing provides no information about production capacity, quality management certifications (such as ISO 9001), export licence status, or years in operation. Direct communication with the supplier is essential to verify manufacturing capabilities, quality control processes, and whether the company trades as a manufacturer, trading company, or brand licensee for the 2UUL product line.
