Products Description
Tungsten copper plates are a type of composite material that combines the properties of tungsten and copper. Tungsten copper plates are made by bonding a layer of tungsten to a copper base, creating a material that takes advantage of the unique characteristics of both elements. Tungsten copper plates are used in various industrial applications where their specific properties are beneficial.
Features of tungsten copper plates:
High Melting Point: Tungsten has an extremely high melting point (about 3422 degrees Celsius), which makes tungsten copper plates suitable for high-temperature applications.
Thermal Conductivity: Copper has excellent thermal conductivity, and when combined with tungsten, the resulting material can efficiently dissipate heat, which is crucial for heat sinks and in high-power electronic applications.
Electrical Conductivity: Both tungsten and copper are good conductors of electricity, making tungsten copper plates suitable for electrical applications.
Wear Resistance: Tungsten is known for its hardness and wear resistance, which is beneficial in applications where the plates may be subjected to abrasion or wear.
Corrosion Resistance: The copper layer provides some corrosion resistance, although tungsten itself is not particularly corrosion-resistant. The combination can offer a balance of properties suitable for various environments.
Applications of tungsten copper plates include:
1 Heat Sinks: In high-power electronic devices, where heat dissipation is critical, tungsten copper plates can be used as heat sinks to prevent overheating.
2 Electronic Packaging: Tungsten copper plates can be used in electronic packaging to connect components and dissipate heat.
3 Machining and Cutting Tools: The wear-resistant properties of tungsten make these plates suitable for use in cutting tools and dies.
4 Aerospace and Defense: In the aerospace and defense industries, tungsten copper plates can be used for their high melting point and thermal properties.
5 Electrical Discharge Machining (EDM): Tungsten copper plates can be used as electrodes in EDM due to their good electrical and thermal conductivity, as well as their wear resistance.
