Key features

Tungsten alloys generally have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co,Mo,Cr, etc .

Tungsten content in conventional heavy alloys varies from 85 to 97 weight percent and is the reason for their high density, the density between 16.5 and 18.5 g/cc

It could be made as various shapes, such as rod, cube, block, brick, ring, etc.

AI-Powered supplier vetting

SummaryThe supplier demonstrates established manufacturing and export experience, operating five production lines and reporting 12 years of export experience. Its quality system includes raw-material traceability, 100% finished-product inspection, documented inspection instructions, quality assurance, corrective-action procedures, and complaint-handling procedures. It offers sample-based, full, and flexible customization, as well as ODM and OEM services. However, evidence is limited or unfavorable for several support capabilities: there is no in-stock capacity, overseas warehouse, overseas showroom, overseas agent or branch, or offline trade-show participation. The supplier reports no valid manufacturing-capacity contract with related subcontractors and has no SDK. Financial information is only represented by reporting years, without performance details. Customer evidence includes technology-transfer and machinery-use examples in Pakistan and another developing-country project, but no Fortune 500 cooperation.

Supplier typeThe supplier operates five production lines and provides manufacturing equipment, with export terms including FOB, CIF, and CFR. Its stated primary export market is domestic, while separate records confirm 12 years of international trade experience, indicating a manufacturer with established but not predominantly overseas market coverage.

CertificationsThe slices confirm raw-material traceability, 100% finished-product inspection, documented and uniformly followed inspection instructions, quality assurance, and recorded corrective-action and complaint-handling procedures. However, no specific third-party certification is identified, so the assessment is based on internal quality controls rather than named certifications.

R&D capabilityThe supplier offers ODM services and describes transferring machine-related technology to support overseas bag production. It also reports no available SDK, so the evidence supports practical product and technology customization but not software-development or platform-integration capability.

Production capacityProduction capacity is supported by five production lines, one-month stated lead times in both peak and off-peak seasons, raw-material traceability, and 100% finished-product inspection. However, the supplier has no in-stock capacity and no valid manufacturing-capacity contract with related subcontractors, indicating reliance on planned production rather than inventory or contracted backup.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, and flexible customization, along with ODM and OEM services. Its description also cites technology transfer connected with machine use, providing direct evidence of tailored product and technical support.

Client casesThe supplier cites projects in Pakistan and another developing country where customers used its machines to manufacture monofilament bags, including technology transfer that helped local production. It reports no cooperation with Fortune 500 companies, so the available cases demonstrate practical international application but not top-tier corporate references.
