Abstract
Tungsten wire is a critical material used in many high-temperature, high-pressure and high-impact applications. It has excellent high-temperature performance and excellent corrosion resistance, and its tensile strength and fatigue resistance are also very good. Therefore, tungsten wire is often used in many fields such as aerospace and energy. The anti-sag performance of tungsten wire has important practical significance in the fields of aircraft structures and civil nuclear power safety.
Introduction
Tungsten (W) is a refractory metal that occurs naturally in most parts of the world and has a melting point of 3422 °C and a boiling point of 5900 °C. It has the highest-known melting point and the highest-known density of all elements. Therefore, it has very good physical, chemical and mechanical properties, such as high resistance to corrosion, high tensile strength and fatigue resistance, and good electrical and thermal conductivity.
Tungsten has been widely used in the aerospace, defense and civil nuclear power sectors where it has been used for different purposes. Due to its excellent high temperature resistance and other properties, as well as its strength and durability, tungsten wire is the main material used for aerospace and nuclear power wiring. Tungsten wires anti-sag performance is crucial for safety in these industries.
Background
Wire sag, also known as wire droop, is the phenomenon of a wires length drifting in positive or negative direction under its own weight due to external force and temperature conditions. In the aerospace industry, wires and cables must be designed and installed to meet strict requirements because they are used to power, control and monitor various systems and subsystems. Hence, wire sagging can be highly dangerous and can cause electrical circuit failures, interference with other wire runs, and even destruction of aircraft. Therefore, the anti-sag performance of the wire is one of the most important criteria for determining the suitability of its use in the aerospace industry.
In addition, wire sagging is also of great importance in civil nuclear power plants. Due to the close spacing between conduits and other structures, wire sagging can cause similar circuit failures or obstruction of vital systems. Therefore, it is important for wire and cable manufacturers to design and manufacture high-performance products that are able to withstand the severe conditions encountered in civil nuclear power plants.
Anti-Sag Performance of Tungsten Wire
Tungsten wire has excellent high temperature performance, corrosion resistance, and tensile strength. Therefore, it has great advantages in aerospace and civil nuclear power applications. The anti-sag performance of tungsten wire is also very good and is determined by its mechanical properties.
Tungsten wire has high corrosion resistance which allows it to maintain its structural integrity and strength over time, even under extreme conditions. In practical applications, the wire is usually made into cables or braided wires so that it can withstand large forces. The wire also has high elastic modulus, low elongation and excellent fatigue strength which give it a higher anti-sag performance.
In addition, tungstens high temperature resistance also helps to improve its anti-sag performance. It can withstand high temperatures without deforming, sagging or losing its strength and flexibility.
Conclusion
Tungsten wire is widely used in many industries due to its excellent high-temperature performance and other properties. The anti-sag performance of tungsten wire is also very good and is mainly determined by its tensile strength, fatigue resistance and corrosion resistance. Its high temperature resistance also helps to improve its anti-sag performance. This makes tungsten wire a reliable and safe choice for many applications in the aerospace and nuclear power industries.
