Key features

Adjustable Thermal Expansion: Thermal expansion coefficient can be adjusted to match ceramics, semiconductors, and metals like Kovar.

High Thermal Conductivity: Combines tungsten's low expansion with copper's high thermal conductivity for efficient heat dissipation.

Longer EDM Electrode Life: Superior to graphite electrodes in spark erosion, offering longer service life and better geometric accuracy.

Versatile Machinability: Can be machined into various shapes including sheets, tubes, plates, and complex electrodes.

Wide Application Range: Used in aviation, electronics, medical, industrial, and chemical fields for heat sinks and electrical contacts.

Customizable Specifications: Available in multiple purity grades (W50-Cu75) and custom shapes with machined or ground surface conditions.

Strict Quality Control: 100% visual inspection by QC department ensures no defective goods reach the warehouse.

Flexible Delivery Options: Delivery time is 10-25 days, with options for express, air, or sea freight based on weight.

AI-Powered supplier vetting

SummaryCombat Company is a combined company with its own production plant and an integrated tungsten, molybdenum, titanium, tantalum, and niobium production line from powder to rods and plates. It supports OEM, ODM, sample-based, design-based, flexible, minor, and full customization, and reports quality assurance, inventory capability, qualified suppliers, and approximately 16 years of export experience. However, it is not identified as a professional technical supplier, provides no 3D software design or SDK, has no overseas warehouse, showroom, agent, or branch, and has not participated in offline trade shows. Several management controls have procedures but no written records, including supplier assessment, finished-product inspection, corrective and preventive action, and complaint handling. Material traceability is also absent. No explicit certification holdings or customer case details are provided.

Supplier typeThe supplier is classified as a combined company and is described as a manufacturer and exporter of tungsten, molybdenum, titanium, tantalum, and niobium products. It has its own production plant and is not identified as a professional technical supplier.

R&D capabilityThe supplier reports no new products during the past year, no available SDK, no 3D software design service, and no professional technical-supplier R&D capability. Its ODM service demonstrates design-manufacturing support, but the overall evidence does not establish strong innovation capability.

Production capacityThe supplier has its own plant with a production flow from powder to rods and plates, inventory capability, 10 qualified service-capability suppliers, and stated peak- and off-season lead times within 15 working days. However, it lacks a valid manufacturing-capacity contract with related subcontractors, so production governance is not fully documented.

Customization capabilityThe supplier explicitly supports customization from designs and samples, flexible customization, minor customization, and full customization. It also provides ODM and OEM services, indicating broad documented customization and contract-manufacturing capability.

Product Q&A

Q:What information is needed for a quotation?

Please provide material dimensions (Thickness*Width*Length or diameter*length), drawings if possible, surface condition, tolerance, quantity, mechanical/technical details, and product application.

Q:How is product quality guaranteed?

Each production step and finished product undergoes inspection by the QC department. Defective goods are not allowed in the warehouse.

Q:Can you guarantee prompt delivery?

Yes, we evaluate competitive prices and determine the most reasonable delivery time upon receiving inquiries to ensure prompt delivery.

Q:How is shipping cost determined?

Shipping cost depends on the destination port, weight, packing size, and total CBM. We strive to get the most reasonable rates from forwarders to save you money.

Q:What are the physical properties of W-Cu alloys?

Properties vary by composition. For example, W90Cu10 has a density of 17.0 g/cm3, thermal conductivity of 180-190 W/M.K, and thermal expansion of 6.5 (10-6/k). W50Cu50 has a density of 12.2 g/cm3, conductivity of 310-340 W/M.K, and expansion of 12.5 (10-6/k).
