Products Description
Tungsten Copper Sheets are made of tungsten copper alloy which combines the advantages of tungsten and copper. This material combines the properties of both metals, featuring characteristics such as high-temperature resistance, resistance to burning and erosion, high thermal conductivity, high electrical conductivity, and ease of processing. It also exhibits the ability to resist arc erosion, mechanical wear, and contact welding.
Copper tungsten sheets are highly favored in fields with high requirements for density, thermal conductivity, and thermal expansion coefficient.
Tungsten-copper sheets are essential products in the refractory metal industry, meeting the growing demands in high-tech applications such as semiconductor electronic devices, safety equipment, counterweight pads, electrical discharge machining (EDM) equipment, resistance welding equipment, high and medium voltage switches or circuit breakers, and other electrical and thermal applications.
features
High thermal conductivity: Copper-tungsten sheets have excellent thermal conductivity, which helps dissipate heat effectively. This makes them perform well in applications requiring efficient thermal management.
High mechanical strength: Tungsten is one of the densest metals known, providing outstanding wear resistance, erosion resistance, and deformation resistance under high pressure. The tensile strength of this material can reach 350-560 MPa.
Good electrical conductivity: Although tungsten has a high melting point, the high conductivity of copper makes copper-tungsten sheets useful in applications requiring good electrical conductivity.
High and low temperature resistance: Copper-tungsten sheets can work effectively in both high and low-temperature environments, making them ideal for aerospace, military, and industrial applications.
Good machinability: Copper-tungsten sheets are easy to process and can be cut, drilled, milled, and more.
Low thermal expansion coefficient: Copper-tungsten sheets have a low thermal expansion coefficient, which helps maintain dimensional stability during temperature changes.
applications
EDM (Electrical Discharge Machining) Electrodes:
Copper-tungsten sheets are ideal for EDM electrodes due to their high melting point and good electrical conductivity.
Resistance Welding Electrodes:
This material is suitable for resistance welding electrodes because it can withstand high temperatures and mechanical stress.
Heat Sinks and Thermal Spreaders:
In high-power electronic components, copper-tungsten sheets work well as heat sinks or thermal spreaders, effectively dissipating heat.
Aerospace Applications:
Copper-tungsten sheets are used in rocket nozzles, missile casings, and other parts that must endure extreme conditions.
Electronics and Semiconductor Industry:
In semiconductor manufacturing, copper-tungsten sheets help with thermal management, preventing failures caused by thermal stress.
Nuclear Energy Applications:
Due to their radiation resistance and high-temperature performance, copper-tungsten sheets are valuable in nuclear reactors and radiation shielding.
