Tungsten copper has been in use for decades, and is now an essential element in the manufacturing process of many products, from aerospace and defense applications to semiconductors. Tungsten copper is made up of two highly conductive metals, tungsten and copper, with an average Cu/W ratio that ranges from 50/50 to 75/25. On a molecular level, tungsten has a well-defined atomic structure while copper has an atomistic structure, and when these two metals are combined they form a unique material with unique properties.
Tungsten copper is strong but malleable, allowing it to be shaped and molded into various manufacturing parts. This metal has a low coefficient of thermal expansion, a high tensile strength and a high electrical conductivity. Its stability makes it especially useful for high-temperature applications and electronics. Its metal characteristics also allow it to resist corrosion and oxidation.
Tungsten copper is primarily used as an electrical contact material in relays and connectors for automotive and industrial applications. Copper offers greater electrical conductivity than tungsten and improves the thermal shock resistance of tungsten. Furthermore, due to its low thermal expansion, tungsten copper is often used as a joining material in the aerospace and defense industry.
Moreover, tungsten copper is often used in high-temperature applications, such as furnace components and heat exchangers. It is also used in semiconductor packaging and die bonding, where its low electrical contact resistance is a great asset. Its use is also common in the electronics industry as solderable or brazeable contacts. In addition, it is also used as heat sinks in cases where heat transfer is required.
Overall, tungsten copper has unique properties that make it suitable for many types of applications. It is strong, malleable, and has a low coefficient of thermal expansion, making it a great choice for high temperature applications. Its high electrical conductivity and its ability to resist oxidation and corrosion make it an ideal material for electronic components. Furthermore, its metal characteristics make it an excellent choice for joining and electrical contact applications.
