AI-Powered supplier vetting

SummaryShaoxing Tianlong Tin Materials Co., Ltd. is a China-based limited company established in 1997, with 157 employees and operations in Zhejiang. Its stated activities include non-ferrous metal rolling, electronic-specific materials manufacturing, and sales. The supplier reports production equipment including traction and smelting furnaces, pressing, wire drawing, and rolling machines. It provides broad customization and ODM services, maintains written inspection, supplier-management, corrective-action, and complaint-handling procedures, and reports quality assurance. Export sales account for 31%–40% of total sales, and products are sold to more than 20 countries and regions. However, it has no valid manufacturing-capacity contract with associated subcontractors, no overseas agents, branches, warehouse, or showroom, and no offline trade-show participation. No recent new-product development, SDK, national science and technology progress award, or popular-brand OEM capability is reported. Financial records are...

Supplier typeThe supplier is identified as a combined limited company established in China, operating in Zhejiang, with business activities covering non-ferrous metal rolling, electronic-specific materials manufacturing, sales, and related services. This provides clear legal and operational classification, but the slices do not identify it as a specialized manufacturer only.

After-Sales capabilityThe supplier has written procedures and records for handling customer complaints and corrective/preventive actions, supports multiple payment and quotation terms, and has in-stock service capacity. However, it has no overseas agents or branches, overseas warehouse, showroom, or stated overseas service coverage, limiting evidence of localized after-sales support.

R&D capabilityThe supplier provides ODM services and broad design customization, indicating some design-related capability. Conversely, it reports no new products in the past year, no available SDK, and no national science and technology progress award, so strong recent innovation capability is not demonstrated.

Production capacityProduction evidence includes traction and smelting furnaces, pressing, wire drawing, and rolling machines, a stated in-stock capacity, 50 qualified service-capability suppliers, one-month average lead times in both peak and off-season, and quality assurance procedures. A deficiency is also reported: there is no valid manufacturing-capacity contract with associated subcontractors, creating a documented capacity-governance weakness.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and also provides ODM services. These statements directly demonstrate broad customization coverage.

Product Q&A

Q:What is the chemical composition of the solder wire?

The wire is an Sn-Zn-Sb-Cu alloy. Specific compositions vary by model (e.g., SZSC-1 has 79-81% Sn, 1-1.5% Sb, 0.3-0.5% Cu). Impurities like Pb and Cd are kept below 0.05% and 0.002% respectively.

Q:Is this product lead-free and compliant with environmental standards?

Yes, it is a lead-free metal spraying material that conforms to EU RoHS and REACH regulations, as well as relevant domestic environmental protection laws.

Q:What are the main applications for this solder wire?

It is primarily used for metal spraying on the end face of metalized film capacitors, particularly as an underlayer material for pure aluminum film in electronics, automobiles, and aerospace.

Q:What are the available diameter options and tolerances?

Diameters range from 1.0mm to 3.20mm. Tolerances vary by size: +/-0.03mm for 1.0-1.65mm, +/-0.04mm for 1.65-2.00mm, +/-0.05mm for 2.00-2.30mm, and +/-0.06mm for 2.30-3.20mm.

Q:What packaging options are available for this product?
