The tungsten iridium stream mouth is as a special tungsten heavy alloy with other refractory metals. It mainly uses in rare-earth metal smelting, the induction furnace heating element, the quartz glass smelting and so on, makes the high temperature vessel.

In the glass and the ceramic industry, the tungsten iridium stream mouth is a ceramic micro production very essential part. The tungsten proportion is big, degree of hardness is big, the heat conduction electric conductivity good, heat-resisting, wear-resisting, anti-corrosive, has the low expansibility and the size stability under the high temperature. The tungsten melting point is highest when all metals (reaches as high as 3380 degrees Celsius), the steam tension to be lowest, the tensile strength is highest (1650°C), and its antiseptic property is good, the majority inorganic acid are very small to its corrosion. Therefore it is ideal to manufacture heavy alloy. But the tungsten and the iridium make the alloy, its abrasion resistance, degree of hardness, the intensity, the heatproof quality obtained the further promotion, thus has guaranteed the product uniformity well. Is precisely these precious performance, causes it to become now in the high-tech crystal glass industry the indispensable equipment component.

In 2012 India International Defense Exhibition, Israel revealed two new 125 mm tank shells, namely the multi-purpose M710 tracer grenades tungsten alloy penetrator (HE-MP-T) and MK-2 tracer APFSDS (OF APFSDS-T) tungsten alloy penetrator, R & Dproviders Israel Military Industries Ltd. These two types of shells to enhance the operational viability of the Indian Army main battle tanks.

M710 can be used to as a typical asymmetric warfare and urban combat environment, 125 mm tank gun fired multipurpose tracer grenades, designed for T-90 T-80 and T-72 main battle tanks, the Israeli militarythe industry's latest multi-purpose tank shells. M710 electronic fuze system, there are three different modes of action: delay detonation (PDD), touched deep-fried (PD) and air-burst (AB). Target information provided by the tank fire control system, fire control system can be programmed via a wireless data link electronic fuzes when tank shells in the gun bore.

Israel Military Industries, R & D, another known as the 125 mm tank shells MK-2 tracer APFSDS tungsten alloy penetrator, second-generation high-speed kinetic energy penetrators. When using the 125 mm tank gun fired, MK-2 tungsten alloy penetrator improved accuracy, within the scope of the full range of reducing the wear and tear on the barrel and enhances the penetration of armored targets.

Applications which might gain more importance in the future are construction material for the tungsten alloy plasma technique in magneto hydrodynamic power generation (W and W-Cu) and target plates in fusion reactors (W, W-La2O3).

Recent plasma technique and theoretical and numerical studies show that tungsten may be the best, if not the only, material to withstand the extraordinary operating conditions in a nuclear fusion reactor diverter. The diverter, being that part of the vacuum vessel where the tungsten alloy plasma technique particles interact with the first wall, and where a large fraction of the fusion heat is removed, consists of water-cooled copper heat-exchanger element covered with a plasma facing armor. The tungsten alloy plasma techniqueparticles (electrons, protons, and α-particles) are directed by the magnetic field toward the diverter target plates, where they are neutralized and pumped. The convective heat flux reaches 20 MW.m-2 and the attendant surface temperature more than 3000℃. Therefore, a suitable armor material must have a high thermal conductivity (in order to transfer high heat fluxes), low thermal expansion coefficient and low Young’s modulus (in order to keep thermal stresses low), and a high melting point and low sputtering yield (in order to keep erosion low). Although tungsten does not have as high a thermal conductivity and as low a Young’s modulus as carbon-carbon composite materials, which are foreseen for the sections of the diverter with the highest heat flux, many experts believe that, in the long run, reasonable lifetimes will only be achieved by tungsten diverter plates, which have the lowest erosion rates of all materials in sections of the diverter with relatively low plasma temperature but high particle density.

For the technical realization of low-pressure plasma processes, one requires equipment with the following components:
Vacuum system (pump, vessel)
Energy supply
Gas supply
Measurement and control components for the reproducible adjustment of the process parameter
Due to the necessity of a vacuum system in most cases, batch operation method is the easiest solution.

The processes can be flexibly and complexly configured, in order to change the mode of action of the tungsten alloy plasma technique through variation of the process parameters (pressure, gas flow, gas composition, power) and can attain different effects in one process step. So that, i.e. without great expenditure a secondary cleaning can be carried out and immediately thereafter a corrosion protection layer becomes deposited, without having to aerate in between.

Most of tungsten granules present transcrystalline cleavage fracture. Binder phase presents ductile fracture and shows better mechanical properties. Remaining organics are not deprived completely during thermal derosination. So, precious few parts in sample have foreign impurities. Those foreign impurities are the key factors for influencing mechanical properties. For that, compared with tensile strength detection result of standard tensile sample, tensile strength of matter sample is low.

Most of tungsten granules present transcrystalline cleavage fracture. Interface of tungsten granules breach and tungsten granules are smashed. What is different is that individual white foreign impurities exist in fracture pattern. Because of large sizes of samples, previously few high polymer organics are not deprived completely and produce carbon inclusions. For that, impact ductility of matter samples is low.
