Characteristics of tungsten-copper?

Resistance welding electrode: It combines the advantages of tungsten and copper, featuring high temperature resistance, arc erosion resistance, high strength, high specific gravity, good electrical and thermal conductivity, easy machining, and sweating cooling characteristics. Due to its high hardness, high melting point, and anti-adhesion properties of tungsten, it is often used as a wear-resistant and high-temperature resistant projection welding and butt welding electrode.

What is tungsten-copper?

What is tungsten-copper?

Tungsten-copper refers to an alloy composed of tungsten and copper, with a common copper content ranging from 10% to 50%. The alloy is produced using powder metallurgy methods and exhibits excellent electrical and thermal conductivity, good high-temperature strength, and a certain degree of plasticity. At very high temperatures, such as above 3000°C, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the surface temperature of the material. Therefore, this type of material is also known as a metal sweating material.

What is the heat sink method in LED packaging?

What is the heat sink method in LED packaging?

The term "heat sink" refers to heat dissipation. Therefore, the purpose of using a heat sink in LED packaging is to add heat dissipation fins or increase the contact area on one junction surface of the LED, in order to achieve effective heat dissipation.

What is the difference between a heat exchanger and a heat sink?

What is the difference between a heat exchanger and a heat sink?

In industrial applications, a heat sink typically refers to a miniature cooling device used to cool electronic chips. On the other hand, a heat exchanger is a device designed to transfer heat from a hot fluid to a cold fluid, meeting specific process requirements.

Are heat sink materials and electronic packaging materials the same concept?

Are heat sink materials and electronic packaging materials the same concept?

No, they are not the same concept. Heat sink materials are specifically designed for use as heat sinks, while electronic packaging materials encompass a much broader range of materials, making it a larger concept. Some heat sink materials can be used for electronic packaging, but not all of them.
