Tungsten-Copper Composite Materials: A New Type of Material with Excellent Performance

Copper-tungsten Composite Materials are a new type of material composed of tungsten and copper, which have attracted much attention due to their excellent properties. Here are some introductions to this material:

Composition and Structure: Copper-tungsten Composite Materials are composed of tungsten and copper, which do not form solid solutions or intermetallic compounds between them, but exist independently and uniformly as their respective metal components. Therefore, it was initially referred to as “pseudo-alloy” and later classified as “composite materials”.

Thermal Properties: Copper-tungsten Composite Materials possess unique thermal properties. Under high temperature, copper will melt, evaporate, and absorb heat from the material surface, producing a cooling effect on the tungsten matrix, similar to human sweating to reduce body temperature. This characteristic makes Copper-tungsten Composite Materials a kind of metal sweating material.

Electrical Processing Performance: Copper-tungsten Composite Materials also exhibit good electrical processing properties. As the thermal expansion coefficients and thermal conductivity of tungsten and copper can be designed by adjusting the material composition, this material can form a good thermal expansion match, suitable for various electrical processing applications.

Nano Copper-tungsten Composite Materials: Nano Copper-tungsten Composite Materials are a special form of Copper-tungsten Composite Materials, with particle sizes generally ranging from 1 to 100 nanometers. This material possesses many excellent physicochemical and mechanical properties, such as small size effect, surface effect, quantum size effect, and macro quantum tunneling effect. These properties enable Nano Copper-tungsten Composite Materials to exhibit superior performance in thermology, magnetism, optics, superconductivity, and catalytic properties.

Preparation Process: The preparation process of Copper-tungsten Composite Materials usually involves powder metallurgy technology. The specific steps include pressing the powders into a shape under a certain pressure, then placing them in a sintering furnace, and finally obtaining the desired Copper-tungsten Composite Materials after a series of heating and heat preservation processes.

In summary, Copper-tungsten Composite Materials are new materials with excellent properties and have broad application prospects in various fields. With the continuous development of science and technology, the properties and application fields of Copper-tungsten Composite Materials will be further expanded and deepened.
