AI-Powered supplier vetting
SummaryThe supplier is a combined company specializing in manufacturing and exporting tungsten heavy alloy products. It holds ISO9001:2015 certification, has documented quality and service procedures, and supports customization, ODM, and OEM services. Export experience spans 23 years, with 51%–70% of sales from exports and shipments to Europe, America, and Japan. R&D is active, with three engineers, new products reported in the past year, and available design documentation, but no SDK and no R&D patents are reported. Customer service procedures and corrective-action records are documented, while overseas service coverage is listed as zero. Financial information identifies reporting years but provides no assessable financial results. No cooperation with Fortune 500 companies is reported, and production scale or capacity metrics are not provided.
Supplier typeThe supplier is identified as a combined company and describes itself as a manufacturer and exporter specializing in tungsten heavy alloy products. This indicates an integrated manufacturing/export business rather than a purely trading or offshore entity.
CertificationsThe supplier reports ISO9001:2015 certification in its company description, sustainable development information, and management-system information. The repeated certification evidence supports a positive assessment of formal quality-management certification.
After-Sales capabilityThe supplier has written procedures and followed records for service assessment, corrective and preventive actions, and customer complaints. However, overseas service coverage is listed as zero, so the evidence supports procedural capability but not broad overseas service availability.
R&D capabilityThe supplier reports new products during the past year, ODM capability, three R&D engineers, and available design input, output, review, verification, and validation documents. Against this, it reports no available SDK and zero R&D patents; overall innovation activity is evidenced, but patent and SDK capabilities are absent.
Production capacityThe supplier manufactures customized tungsten sheet, plate, foil, and strip, follows uniform finished-product inspection instructions, and reports nine quality-control test equipment items. Export logistics and one-month peak and off-season lead times are stated, but production capacity or output volume is not provided.
Customization capabilityThe supplier explicitly offers customization from samples and designs, produces products according to drawings and requests, and provides ODM and OEM services. These multiple statements directly support strong customization capability.
Client casesThe supplier reports exports to Europe, America, and Japan and states that it provides OEM services for well-known brands. It also reports no cooperation with Fortune 500 companies, so customer experience is evidenced but specific named cases and top-tier corporate references are limited.
Product Q&A
Q:What are the main applications of Sintered Tungsten Copper Alloys?
A:
They are extensively used for electrical contacts, heat sinks, EDM electrodes, fuel injection nozzles, resistance welding electrodes, circuit breakers, and heavy-duty contactors.
Q:What compositions are available for these electrodes?
A:
Standard compositions include WCu 70/30, WCu 75/25, WCu 80/20, and WCu 90/10. Custom compositions like 65%W35%Cu are also available.
Q:Can the size and shape of the electrodes be customized?
A:
Yes, diameter and length can be standard or by drawing. Shapes include wires, rods, bars, strips, foils, blocks, plates, and rings.
Q:What are the key physical properties of Tungsten Copper?
A:
Key properties include high density, low thermal expansion, high thermal and electrical conductivity, and high resistance to arc-erosion.
Q:What is the lead time for orders?
A:
The average lead time is one month for both peak season and off-season.
