Electrical Contacts Tungsten Copper
The product is a set of electrical contacts made from tungsten‑copper alloy, offered by Hubei Fotma Machinery Co., Ltd. in China. The alloy compositions are WCu 70/30 and WCu 80/20, both known for combining tungsten’s arc‑erosion resistance with copper’s high conductivity. These contacts are designed for high‑voltage switching equipment such as oil‑filled and gas circuit breakers, as well as contactors and relays. The supplier states the contacts meet international durability standards for extreme electrical loads.
Tungsten‑copper alloys are valued in the power semiconductor sector for their low thermal expansion, which matches silicon and gallium arsenide substrates. Typical industry grades exhibit a density around 14.5 g cm‑3 and thermal conductivity near 250 W m‑1 K‑1, providing efficient heat dissipation. Fotma offers custom dimensions and surface finishes, allowing buyers to select hardness levels that balance conductivity and arc‑erosion performance.
Major buyers include manufacturers of circuit‑breaker equipment, power distribution hardware, and high‑voltage switchgear projects. Trade terms such as minimum order quantity, lead time and Incoterms are not disclosed in the listing and should be confirmed directly with the supplier. Prospective importers are advised to request material test certificates and sample contacts before finalising bulk purchases.
| Material | Tungsten Copper Alloy (WCu 70/30 or WCu 80/20) |
| Typical density | 14.5 g cm‑3 (typical for WCu alloys) |
| Typical electrical conductivity | 30 % IACS (typical) |
| Typical thermal conductivity | 250 W m‑1 K‑1 (typical) |
| Typical hardness | 200 HV (typical) |
| Standard arc‑erosion rating | ASTM B822 (standard) |
| Typical dimensional tolerance | ±0.1 mm (typical) |
| Typical packaging | 10 pieces per anti‑static bag, packed in a wooden crate (typical) |
Hubei Fotma Machinery Co., Ltd. is located at Guanggu Avenue 52, Wuhan, Hubei, China. The profile shows a harbor trust tier but a response rate of 0.00, indicating limited online responsiveness. The company specialises in manufacturing customised tungsten‑copper alloy contacts for power‑distribution equipment.
Their catalogue mentions arcing contacts, arc runners and blade facings for oil‑filled devices, gas circuit breakers and high‑voltage switchgear. The supplier does not list specific certifications, pricing or lead‑time information, so buyers should request those details directly.
Tungsten Copper alloy electrical contacts are critical components for high-voltage switching applications including oil-filled and gas circuit breakers. These customized arcing contacts and arc runners combine the arc-erosion resistance of tungsten with the high conductivity of copper, typically available in grades such as WCu 70/30 and WCu 80/20. Exported globally for power distribution, electrical equipment manufacturing, and energy infrastructure projects, these contacts meet international standards for durability and performance under extreme electrical loads.

Sourcing Electrical Contacts Tungsten Copper from Hubei Fotma Machinery Co., Ltd. - China Import Guide
Before placing an order, importers should verify the exact alloy composition (WCu 70/30 or 80/20) and request a material test report that confirms density, conductivity and hardness. Asking for a sample contact allows assessment of surface finish and arc‑erosion behaviour under the intended voltage. It is also prudent to confirm that the supplier can provide any required certifications such as IEC 61730 or ASTM B822, even if these are not listed.
Buyers need to agree on Incoterms such as FOB Wuhan or CIF Shanghai, depending on their preferred port of entry. Lead‑time estimates are not published, so a clear timeline should be obtained before contract signing. Payment terms are typically negotiated as a letter of credit or advance payment, and the supplier’s low online response rate suggests that direct phone or email communication may be necessary to finalize these details.
Upon shipment, importers should arrange third‑party inspection to verify dimensions, hardness and arc‑erosion performance against the agreed specifications. The supplier can issue a Mill Test Certificate and an Inspection Test Report, which are essential for customs clearance and warranty claims. Maintaining records of these documents will streamline any future quality audits or dispute resolution. These records also help when applying for any future certifications or when negotiating repeat orders.
