What are the key characteristics of tungsten heavy alloys?

Key characteristics include the highest melting point of all metals, high density (more than twice that of steel), low thermal expansion, and high dimensional stability.

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 is the warranty period for these products?

We provide a full two-year warranty for all our fabricated tungsten alloy components.

Q:What are the main applications for these sinker bars?

They are primarily used in oil and gas drilling as sinker bars for downhole logging tools, as well as for radiation shielding, vibration absorption, and balance weights.

Q:Is the product lead-free?

Yes, our lead-free components meet legal requirements and recommendations to protect the environment.

Q:What customization options are available?

We offer customizable density, tungsten content (90%, 92.5%, 95%, 97%), and mechanical properties like tensile strength and hardness.

Q:What is the average lead time for orders?

The average lead time is one month, regardless of whether it is peak season or off-season.
