Tungsten Copper Alloy Heat Sinks
The product offered is a tungsten copper alloy heat sink fabricated from a 70% tungsten and 30% copper composition. The alloy is precision‑machined to provide high thermal conductivity and a low coefficient of thermal expansion, making it suitable for high‑power electronic modules. Supplier Hubei Fotma Machinery Co., Ltd. states that the heat sinks can be customised in shape and size to match specific device footprints.
Tungsten‑copper composites combine the strength and refractory properties of tungsten with the excellent heat‑transfer capability of copper. Typical thermal conductivity for a 70‑30 alloy is around 210 W·m⁻¹·K⁻¹, and the material can tolerate operating temperatures up to roughly 800 °C. Standard density is about 15 g·cm⁻³, while the coefficient of thermal expansion is typically 6.5 µm·m⁻¹·K⁻¹, which matches many semiconductor packages and reduces thermal stress.
Common applications include cooling of power electronics, LED lighting modules, laser systems and aerospace control units. Buyers such as OEMs, system integrators and contract manufacturers often request flexible minimum order quantities and shipping under FOB or CIF terms. Payment can be arranged via L/C or T/T, and the supplier mentions ISO and SGS certifications that can be reviewed on request.

Sourcing Tungsten Copper Alloy Heat Sinks from Hubei Fotma Machinery Co., Ltd. - China Import Guide
Before confirming an order, importers should request the latest ISO and SGS certificates, as well as a material test report that confirms the tungsten‑copper ratio and thermal conductivity. Verifying the supplier's production capabilities and any custom‑machining lead times will reduce the risk of mismatched specifications.
Logistics should be arranged through the nearest major port in Wuhan, with shipping terms clarified as either FOB or CIF. Buyers need to agree on the incoterm, arrange freight forwarder details, and decide on payment method - L/C or T/T are mentioned by the supplier. Confirm the exact freight cost and any required export documentation early in the process.
Quality assurance is best performed by a third‑party inspection agency that checks dimensions, surface finish, and thermal performance against the agreed tolerances. Request an inspection report and, if possible, a pre‑shipment sample. Maintaining records of these checks will support smooth customs clearance and ensure the heat sinks meet the end‑user requirements.
