Tungsten Silver Composite

HOSO brings over a decade of expertise in manufacturing silver tungsten alloys, showcased in our HOSOPM®1 series. Adhering to the stringent standards of GB/T8320-2003 and ASTM B631, our products match the quality of Elkonite 2088, 20S, 30S, 35S, 50S, 4050, 20SB, 35SB, 2110, and 2150. These alloys are widely utilized in various applications, including EDM erosion electrodes, electrical contact tips, and spot welding electrodes, demonstrating their remarkable versatility and reliability

Tungten Silver Process:

HOSO employs an advanced vacuum infiltration technique, known as the PSI process, to produce tungsten silver alloy. This method ensures our silver tungsten products achieve exceptionally high density and electrical conductivity. The production has the following steps: powder mixing, pressing, sintering, infiltration, and machining.

HOSO Tungsten Silver Application and Advantage:

HOSO's AgW stands out as an excellent contact material for heavy-duty switching applications. The combination of high melting temperatures and the robust strength of refractory metals confers exceptional resistance to arc erosion, welding, mechanical wear, and deformation. Additionally, the high conductivity of these metals ensures efficient electrical and thermal conduction, resulting in low contact resistance.

Tungsten Silver Properties:

 The following guidelines pertain to silver-tungsten materials, detailing typical ranges of chemistry and properties for the various available compositions. We can also provide specific compositions beyond those listed.
