The manufacturer of Molybdenum Rhenium tube tells you that rhenium has very excellent properties, so rhenium is added to molybdenum to form a molybdenum-rhenium alloy. The electrical properties, high-temperature ductility and processability of the alloy can be greatly improved and strengthened, and can be widely used in high temperature Heating body, temperature measuring thermocouple, electron tube cathode and other high-temperature components, etc. Molybdenum Rhenium tube manufacturers tell you that molybdenum-rhenium alloy is often used in the manufacture of high-speed rotating X-ray tube targets, long-life grids for microwave communications, and space reactor cores Heating tube, high temperature furnace heating element and high temperature thermocouple, etc.

The manufacturer of Molybdenum Rhenium tube tells you that molybdenum-rhenium alloy is a refractory alloy, so it is generally prepared by powder metallurgy or vacuum melting. Both methods have their own advantages and disadvantages.
The molybdenum-rhenium alloy ingot prepared by the vacuum melting method can well control the impurity content, especially the gas element content is significantly reduced, and the intermediate phase is not easy to precipitate, which is beneficial to the subsequent processing of the molybdenum-rhenium alloy. The grains of molybdenum-rhenium alloy ingots are usually relatively coarse, and the size distribution is uneven, which increases the difficulty of alloy blanking.
The manufacturer of Molybdenum Rhenium tube tells you that compared with the vacuum smelting method, the process of preparing molybdenum-rhenium alloy by powder metallurgy is relatively simple, low in cost, and relatively easy to realize industrialization. Therefore, almost all products currently available for sale use powder metallurgy. Production. But the powder metallurgy method is not easy to control the impurity content in the alloy ingot. Generally, the sintered ingot can be well controlled by vacuum melting.
