Chapter 1 Basic Knowledge of Silver-Tungsten Alloy
As a high-performance composite material, silver-tungsten alloy has shown wide application potential in the electrical, electronic, defense and industrial fields due to its excellent electrical conductivity, thermal conductivity, high temperature resistance and arc corrosion resistance. The alloy is prepared by powder metallurgy process, combining the high electrical and thermal conductivity of silver with the high melting point and hardness of tungsten, and can meet the demanding requirements in high current, high temperature or high wear environment. With the rapid development of electrification and high-power equipment, the importance of silver-tungsten alloy in the fields of electrical contacts, circuit breakers and electrode materials has become increasingly prominent.
1.1 Concept of Silver Tungsten Alloy
Silver-tungsten alloy is a composite material with silver and tungsten as the main components. It is usually prepared by powder metallurgy and is widely used in scenarios that require high conductivity, arc corrosion resistance and high temperature resistance. Silver provides excellent electrical and thermal conductivity, while tungsten contributes high melting point, hardness and wear resistance, making the alloy perform well in electrical contact and high temperature environments. The performance of silver-tungsten alloy can be optimized by adjusting the ratio of silver and tungsten to meet the needs of different applications, such as high-voltage switches, welding electrodes and aerospace electrical components.
1.1.1 Definition of Silver Tungsten Alloy
Silver-tungsten alloy is a composite material made of silver and tungsten through powder metallurgy process. Silver is used as matrix or bonding phase, and tungsten is used as high melting point reinforcement phase. The advantages of both are combined to form a material with excellent performance. The high electrical conductivity and thermal conductivity of silver make it an ideal conductive matrix, while the high melting point and hardness of tungsten give the alloy excellent high temperature resistance and arc corrosion resistance. The preparation process usually includes powder mixing, pressing, sintering and post-processing. Silver forms a liquid phase during the sintering process, wets the tungsten particles, fills the gaps, and forms a dense microstructure. The composition ratio of silver-tungsten alloy is adjustable. When the silver content is higher, the conductivity is better, and when the tungsten content is higher, the wear resistance and high temperature resistance are stronger. It is suitable for scenes such as electrical contacts, circuit breaker contacts, resistance welding electrodes and plasma sprayed parts. Its non-magneticity and low thermal expansion coefficient further enhance its applicability in high-precision electrical and high-temperature environments.
The core advantage of silver-tungsten alloy lies in its comprehensive performance. The high conductivity of silver ensures the efficiency of current transmission and is suitable for high-voltage electrical systems; the high melting point and arc corrosion resistance of tungsten enable the alloy to remain stable in high current or frequent switching operations and extend its service life. The toughness and wear resistance of the alloy enable it to withstand mechanical shock and arc erosion, making it suitable for dynamic electrical environments. The flexibility of the preparation process allows the performance to be optimized by adjusting the silver- tungsten ratio or adding trace elements (such as nickel) to meet specific application requirements. Silver-tungsten alloy is widely used in the electrical and industrial fields to manufacture high-reliability contacts and electrodes, especially in scenarios requiring high conductivity and arc resistance, such as power systems, aerospace electrical connections, and industrial welding.
