The W85 and W75 Tungsten Copper Alloy Bars are pseudo‑alloys composed of 85 % tungsten with 15 % copper (W85) and 75 % tungsten with 25 % copper (W75). They are supplied by Hubei Fotma Machinery Co., Ltd., based in Wuhan, Hubei, China, and classified under HS Code 8101.96 for unwrought tungsten alloys. The bars are machined to ANSI standards, providing dimensional consistency for industrial use. All dimensions and packaging details must be confirmed directly with the supplier.
The copper matrix gives the alloy high thermal conductivity and good electrical conductivity, while the tungsten particles ensure heat resistance and high density. Typical density for such CuW alloys is about 15.5 g/cm³ and thermal conductivity near 150 W/m·K, values that buyers often compare against performance requirements. The material is easy to machine, allowing production of precise bar shapes for electrodes and heat‑sink components. Standard industry specifications such as Brinell hardness 300 - 350 HB are typical for these grades.
Common applications include electrical contacts, EDM and ECM electrodes, welding electrodes and heat‑sink elements in aerospace, electronics and power distribution equipment. Purchasers are usually manufacturers of high‑temperature or high‑current devices who require reproducible conductivity and dimensional accuracy. The supplier’s listing does not disclose minimum order quantity, lead time or payment terms, so importers should request a formal quotation and confirm logistics. Verification of material test certificates and compliance with the stated ANSI machining standards is recommended before finalising the order.

Hubei Fotma Machinery Co., Ltd. is located at Guanggu Avenue 52#, Wuchang, Wuhan, Hubei, China (postal code 430074). The company is listed in the harbour trust tier and currently shows a 0 % response rate with no recorded response time, indicating that buyers should confirm communication channels before engaging.
The supplier’s catalogue focuses on the production of tungsten‑copper alloy bars that are machined to ANSI specifications for use in high‑temperature and high‑conductivity applications. No information on minimum order quantities, pricing, lead times or certification status is provided in the listing, so interested importers must request these details directly from the company.
W85 W75 Tungsten Copper Alloy Bars are high-performance pseudo-alloy materials consisting of 85% and 75% tungsten respectively, bonded with copper. These bars are machined to ANSI standards and widely used in electrical contacts, EDM electrodes, welding electrodes, and heat sink applications where high thermal and electrical conductivity are required. They are critical industrial materials traded globally for manufacturing in aerospace, electronics, and power distribution sectors. HS Code 8101.96 applies to unwrought tungsten alloys including these CuW bars.

Before ordering, importers should verify that the supplier can provide material test certificates confirming composition, density and hardness, and that the bars meet the ANSI machining specifications referenced. Request a sample or mill test report to ensure the product matches your technical requirements and that any required certifications for your market are obtainable.
Logistics arrangements need clarification: ask the supplier which Incoterms they support, typical lead times for production and shipment from Wuhan, and acceptable payment methods such as LC or T/T. Confirm container loading capacities and whether the bars will be pre‑packed or require on‑site handling at the port.
Upon arrival, conduct a visual inspection for surface integrity and dimensional checks against the agreed tolerances. Arrange for third‑party testing of density and conductivity if critical to your application. Ensure the accompanying documentation includes the material test certificate, a declaration of conformity and the appropriate HS code for customs processing.
