Copper Tungsten Sheets

Overview

Copper Tungsten Sheets are a composite material composed of tungsten and copper, combining the high strength and high-temperature resistance of tungsten with the excellent electrical and thermal conductivity of copper. These sheets are typically manufactured through isostatic pressing and high-temperature sintering, resulting in a fine structure and excellent performance. They are primarily used in applications such as electrode materials, contact materials, welding materials, and guide materials. We can also provide other cost-effective tungsten copper products, such as Tungsten Copper Alloy Rod, Tungsten Copper EDM Electrodes, WCu Alloy Electrode Plates, etc. If you need them, you can place an order with confidence.

Application

1. Electronics and Microelectronics

• Chip Heat Dissipation Components: In high-power chips and semiconductor devices, copper tungsten sheets serve as heat sinks or substrates, quickly dissipating heat generated during chip operation and preventing performance degradation caused by overheating. They are particularly suitable for electronic equipment operating in high-temperature environments, such as those in aerospace and military applications.
• Packaging Materials: Used in the packaging of high-reliability electronic components, their matching thermal expansion coefficient (which can be optimized by adjusting the tungsten-to-copper ratio) reduces stress caused by temperature fluctuations and protects delicate internal structures.

2. Power and Electrical Equipment

• High-Voltage Switches and Circuit Breakers: They maintain stability in core components such as contacts and electrodes during high-voltage arcing, extending the service life of switchgear. They are commonly used in power transmission and distribution systems, electric locomotives, and other applications.

3. Machining and Molds

• Electrodischarge Machining (EDM) Electrodes: They are used as electrode materials in mold manufacturing. They offer excellent conductivity and low loss, enabling precise machining of complex shapes in carbide, steel, and other materials. They are particularly suitable for forming precision molds.
• Wear-resistant parts: Used in wear-resistant liners for stamping dies, for example. Leveraging its high strength and wear resistance, it withstands high-frequency impact and friction, making it suitable for the mass production of automotive parts and precision instruments.

4. Aerospace

• High-temperature resistant components used in rockets and aircraft, such as nozzles and combustion chamber liners, must operate under extreme temperatures and pressures. Its high melting point and thermal shock resistance ensure stable operation.

5. Medical

• In medical equipment such as radiotherapy equipment and high-frequency surgical knives, this product can serve as shielding or conductive and thermally conductive components, balancing radiation protection (due to tungsten's high density) with heat dissipation.

Process

① High-purity tungsten powder and copper powder are placed in a mixer and mixed uniformly according to the appropriate ratio.

② The mixed powder is compacted into a "green body" (unsintered body) with a desired shape and strength.

③ High-temperature heating is used to bind the powder particles, eliminate porosity, increase density and strength, and achieve a metallurgical bond between tungsten and copper.

④ For products requiring high dimensional accuracy (e.g., thickness tolerance of ±0.01mm), cutting is performed using grinding or milling machines to correct shape and dimensions.

⑤ Surface treatment is performed, such as electroplating (nickel, silver, etc.) to improve corrosion resistance or conductivity, or polishing to meet appearance requirements (e.g., for precision electronic components).

⑥ Comprehensive quality testing is performed, such as mechanical property testing, dimensional inspection, and appearance inspection.
