Silver-tungsten Alloy

Hotline:
Silver-tungsten alloy is a kind of two-phase structural pseudo-alloy composed of tungsten and silver elements, and is a metal-matrix composite material. With larger differences of physical properties, silver and tungsten cannot be produced by a fusion casting method. Currently, silver-tungsten alloy is generally obtained by a powder metallurgy technology. Technological process: burden mixing -- compression molding -- sintering & infusion -- cold machining. The tungsten-silver alloy has integrated the advantages of tungsten and silver, which include high tungsten melting point (tungsten melting point: 3,410℃) and high density (tungsten density: 19.34g/cm³); silver has superior electric and thermal conductivity, while tungsten-silver alloy (the components generally belong to the range of WCu7~WCu50) features uniform microstructure, high-temperature resistance, high strength, arc ablation resistance and large density.
