Tungsten Bucking Bar


By selecting high purity tungsten and oxygen-free copper, all of our tungsten copper alloy products are manufactured by sintering and infiltrating process or mixed sintering. In terms of different types, the composition of tungsten and copper are well-proportioned. These tungsten copper products possess excellent properties from both tungsten and copper. They are of high arc resistance, good electrical conductivity, high thermal conductivity, low thermal expansion as well as good sweat cooling characteristics.
