      • Overview
        • Silver tungsten is a composite material that combines the beneficial properties of both silver (Ag) and tungsten (W). This alloy is widely recognized for its excellent electrical and thermal conductivity, high melting point, and exceptional strength. The material typically consists of a matrix of silver with embedded tungsten particles.
          Silver Tungsten s high electrical and thermal conductivity, along with its low electrical contact resistance, make it an ideal choice for electrical and electronic applications.
          Silver tungsten is available in various forms, including rods, plates, discs, and custom shapes. These products can be manufactured through powder metallurgy techniques, where silver and tungsten powders are compacted and sintered to form a solid composite.

      • Applications
        • Application Description
          It is commonly used in electrical contacts, switches, relays, and circuit breakers, where reliable and efficient electrical conduction is crucial. The combination of silver superior conductivity and Tungsten s high melting point allows silver tungsten to withstand high current and high-temperature conditions.
          Furthermore, silver Tungsten s exceptional hardness and wear resistance make it suitable for applications that require durability and resistance to friction and erosion. It is often used in electrical discharge machining (EDM) electrodes, welding electrodes, and contact materials for heavy-duty switches and relays.
