AI-Powered supplier vetting

SummaryThe supplier is a Shanghai-based limited trading company with 41 employees, associated companies, and a product scope covering nickel-chromium alloys, FeCrAl alloys, thermocouple wire, copper-nickel alloys, thermal spraying wire, Constantan, Manganin, and related alloys. It reports customization from designs and samples, ODM service, and OEM service for popular brands. Service procedures, corrective actions, and complaint-handling records are documented and followed. However, it reports no valid manufacturing contract with affiliated subcontractors, no overseas warehouse, showroom, agent, or branch, no available SDK, and no new products during the past year. Financial-year references are provided, but financial strength cannot be assessed from the available non-financial evidence.

Supplier typeThe supplier is identified as a limited company and trading company located in Baoshan District, Shanghai. Its stated business scope centers on sales of metal materials, alloys, hardware, electrical equipment, and related products, indicating a trading-oriented business model rather than an explicitly documented owned manufacturing operation.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaints. It offers debugging, has in-stock capability, accepts several service quotation and payment methods, and reports service coverage across the Americas, Asia, Africa, and Europe, but has no overseas warehouse, showroom, agent, or branch.

R&D capabilityThe supplier offers ODM services and customization from designs and samples, but reports no new products during the past year, no available SDK, and no ERP-based digital management. Sustainable-development, big-data, and OA capability entries are recorded as zero, providing no positive evidence of structured innovation or digital transformation.

Production capacityThe supplier reports in-stock capability, a one-month peak-season lead time, an off-season lead time within 15 working days, and 50 qualified suppliers. However, it explicitly lacks a valid contract between the factory and affiliated subcontractors, while the company is classified as a trading company; owned production capacity is therefore not established and subcontracting governance presents a stated deficiency.

Customization capabilityThe supplier explicitly provides customization from customer designs and samples, offers ODM services, and reports OEM service for popular brands. These statements directly support capability for design-based and sample-based customization, although no technical scope, equipment, or project examples are provided.

Product Q&A

Q:What is the main application of Constantan wire?

It is primarily used as the negative element in Type J thermocouples for heat treating and Type T thermocouples for cryogenic temperatures. It is also suitable for AC circuits.

Q:How does Constantan compare to Manganin?

Constantan offers better corrosion resistance than Manganin and maintains a flat resistance/temperature curve over a wider range.

Q:What are the mechanical strength options?

It is available in two states: Annealed/Soft with tensile strength of 340-535 MPa, and Cold Rolled with tensile strength of 680-1070 MPa.

Q:Is the material magnetic?

No, the material has a non-magnetic property due to its austenite micrographic structure.

Q:What are the payment terms?

We accept LC, T/T, D/P, PayPal, Western Union, Small-amount payment, and Money Gram.
