Product name: Tungsten silver alloy

Silver silver tungsten sintered materials of high conductivity, thermal conductivity and high melting point metals tungsten and molybdenum in the high hardness, resistance welding, material transfer of small, high-burning binding as a whole. AG-W electrical contact in the work of current off the air frequently on the surface in electrical contact formation of mixed oxide to form the contact resistance can increase the surface film.
