This Tungsten Iridium Stream Mouth is a special tungsten heavy alloy combined with other refractory metals. It is mainly used in rare-earth metal smelting. In addition, it is also high in demand in the induction furnace heating element. Widely used to make high temperature vessels, this Tungsten Iridium Stream Mouth has excellent degree of hardness, good heat conduction electric conductivity and low expandability. These are widely used for making special glass drill bits for drilling through glass. The standard bearing utilized is a Carbon-Graphite compound in our Tungsten Iridium Stream Mouth that has astounding consumption safe qualities while working in most fluid situations. Certain liquids will assault the folio or process streams may contain rough solids which block the utilization of carbon-graphite bearing. Tungsten Iridium Stream Mouth is made of metal. It is more grounded than titanium rings and longer enduring than gold rings.
