Tungsten Copper Plate

Product Introduction

The Tungsten Copper Plate produced by Shaanxi Chuanghui Daye Metal Material Co., Ltd. is an advanced composite material that combines the high thermal conductivity and electrical performance of copper with the excellent wear resistance and high-temperature strength of tungsten. This unique alloy structure ensures remarkable durability, stable conductivity, and superior resistance to arc erosion and deformation. Manufactured under strict quality standards such as ASTM and GB, the product is widely used in demanding industries including aerospace, electrical power, metallurgy, and electronic devices. Each plate is processed with high precision to deliver consistent performance, dimensional accuracy, and long service life under extreme operating conditions.

Tungsten copper plates and sheets are highly sought-after flat materials for demanding applications such as high voltage, high temperature, resistance welding, and EDM (Electrical Discharge Machining). These materials offer excellent resistance to thermal and electrical erosion, alongside superior conductivity, low thermal expansion, and excellent machinability. The combination of tungsten and copper brings together the best of both metals, making them ideal for use in environments where both strength and electrical efficiency are required.

The characteristics:

1. High temperature resistance: Tungsten copper plate has extremely high temperature resistance and can withstand working conditions in high-temperature environments. The melting point of tungsten is 3410 ℃, while the melting point of copper is 1080 ℃, which allows tungsten copper alloys to maintain stable performance at high temperatures.

2. High strength and arc erosion resistance: Tungsten copper alloy has high strength and good arc erosion resistance, suitable for working environments that require high strength and arc erosion resistance. This characteristic makes tungsten copper sheets widely used in fields such as high-voltage switches and electrode machining.

3. Good electrical and thermal conductivity: Although tungsten has poor electrical conductivity, copper has superior electrical conductivity. Through a reasonable composition ratio, tungsten copper alloy can provide moderate electrical and thermal conductivity while maintaining high strength. This characteristic makes tungsten copper sheet perform well in applications such as electronic packaging and high-voltage discharge tubes.

4. High density and uniform microstructure: The microstructure of tungsten copper alloy is uniform and dense, which helps to improve the stability and service life of the material. The density of tungsten is 19.25g/cm ³, the density of copper is 8.92g/cm ³, and the density of alloys is generally around 16.5g/cm ³.

5. Wide application fields: tungsten copper sheet is widely used in aerospace, electronics, power, metallurgy, machinery and other fields due to its excellent performance. Specific applications include resistance welding electrodes, spark electrodes, high-voltage discharge tube electrodes, electronic packaging materials, etc.
