Funnel Type Tungsten Products Tungsten Iridium Alloy Orifice Tungsten Parts In High Temperature Quartz Glass Furnace

Tungsten has a large specific gravity, high hardness, good thermal and electrical conductivity, heat resistance, wear resistance, corrosion resistance, low expansion and dimensional stability at high temperatures. Tungsten has the highest melting point (up to 3380°C), the lowest vapor pressure, and the highest tensile strength (at 1650°C) of all metals, and its corrosion resistance is very good, with little attack from most inorganic acids.

Iridium has high melting point and chemical stability, high temperature corrosion resistance, and is widely used in utensils in chemical analysis and iridium tubes in tungsten-iridium flow ports for drawing refractory fibers. Because the ratio of iridium's compression modulus to shear modulus is small, the deformation resistance is large, the hardening rate is high, and the processing is difficult, so the production of iridium materials at home and abroad adopts the process of hot rolling with a layer of nickel coated with a blank iridium plate or iridium rod.

The wear resistance, hardness, strength and heat resistance of alloys made of tungsten and iridium have been further improved, thereby better ensuring product consistency. It is these valuable properties that make it an indispensable equipment element in today's high-tech crystal glass industry.

3. Application Of Funnel Type Tungsten Iridium Alloy Orifice:

The tungsten-iridium orifice is mainly used for rare earth metal smelting, induction furnace heating element, quartz glass smelting, etc., as a high-temperature container. In the glass and ceramic industry, the tungsten orifice is a very critical element in the micro-production of ceramics.
