Tungsten wire has the following important functions in shielding materials:
Electromagnetic shielding: Tungsten wire has good conductivity and high density, so it can effectively block and reflect electromagnetic waves. This makes it an ideal choice for electromagnetic shielding materials, especially in situations where electromagnetic interference (EMI) or electromagnetic radiation leakage needs to be prevented, such as the housing of electronic equipment, the shielding layer in communication equipment, etc.
High temperature stability: The extremely high melting point of tungsten allows tungsten wire to maintain its shielding performance under high temperature conditions. This is especially important for shielding materials used in extreme environments, such as in the aerospace field or high-temperature industrial equipment, where tungsten wire can provide reliable shielding effects at high temperatures.
Structural strength: The high strength and hardness of tungsten wire enable it to provide structural support for shielding materials and enhance the durability and mechanical strength of the shielding layer. In some applications, the strength of tungsten wire can prevent shielding materials from being physically damaged during use.
Versatility: Since tungsten wire can be combined with other materials such as metal foil, composite materials, etc. to form a multi-layer shielding structure, it is highly adaptable in a variety of shielding applications. For example, tungsten wire can be embedded in fabrics to form flexible shielding materials, which are suitable for occasions requiring flexibility and durability.
In general, the role of tungsten wire in shielding materials is mainly reflected in its electromagnetic shielding performance, high temperature stability, structural strength and versatility, making it one of the key components of high-performance shielding materials.
