Iridium Tube Function- Production of Tungsten Iridium Stream Mouth

Iridium is the element in Ⅷseries. The Iridium is the main product of Iridium which is characterized by high melting point, boiling point, hardness, density, elastic modulus and corrosion resistance and low Poisson’s ratio. One of its main application is to combine with tungsten in order to produce tungsten iridium stream mouth. 

Iridium tube picture

The iridium tube owns the following properties:

1.0 High corrosion resistance

2.0 High erosion resistance of silicate at elevated temperature

3.0 High erosion resistance of the melting reagent

4.0 Good plasticity at over 1600 centigrade

5.0 High elastic modulus, low Poisson’s ratio and low plasticity at low temperature

6.0 High melting point, boiling point, hardness and density

7.0 Good ductility, electrical conductivity and heat conductivity

Tungsten iridium stream mouth is the combination of tungsten basal body and the iridium tube. Its properties (such as the wear resistance, hardness, strength and so on) got a further improvement so that guarantees the uniformity of products. It is these properties that make it an indispensable component in today's high-tech crystal industry. The density of the tube is not less than 21.00g/cm3, and the purity of iridium is not less than that of SM-Ir99.95 iridium powder in the GB/T 1422. The degree of curvature is not more than 5mm/m, and its internal and external surfaces are smooth without the defects, such as burr, crack and so on.

The stream mouth is widely applied the metallurgy of rare earth metals, the heater of the induction furnace, the smelting of the silex and so on.
