Tungsten silver alloy is a kind of two-phase structure pseudo alloy mainly composed of tungsten and silver. Because the physical properties of silver and tungsten are quite different, it can’t be produced by melting and casting. Instead, it is usually obtained by powder alloy technology. The technological process includes batching, mixing, pressing, sintering, melting, and cold working.
Tungsten silver alloy combines the advantages of metal tungsten and silver, among which tungsten has high melting point (tungsten point is 3410°C) and high density (tungsten density is 19.34 g/m3), while silver has excellent conductivity and thermal conductivity. Tungsten silver alloy (composition generally ranges from wcu7 to wcu50) has uniform microstructure, high temperature resistance, high strength, arc erosion resistance and high density.
Compared with W-Cu alloy, W-Ag alloy has better conductivity, plasticity and oxidation resistance, but lower strength and hardness, and higher price. Please refer to Tungsten Copper Page for our W-Cu products.
