Molybdenum Rhenium sheet manufacturer tells you that rhenium has very excellent properties, so adding rhenium to molybdenum to form a molybdenum-rhenium alloy, the electrical properties, high temperature ductility and workability 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 parts, etc. Molybdenum-rhenium alloy is often used in the manufacture of high-speed rotating X-ray tube targets, long-life grid plates for microwave communication, space reactor core heating tubes, and high-temperature furnace heating body and high temperature thermocouple, etc.

Molybdenum Rhenium sheet manufacturers tell you that molybdenum-rhenium alloys are refractory alloys, so they are generally prepared by powder metallurgy or vacuum melting. Both methods have their own advantages and disadvantages.
Molybdenum Rhenium sheet manufacturer tells you that the molybdenum-rhenium alloy ingot prepared by 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 molybdenum-rhenium alloy However, the grains of molybdenum-rhenium alloy ingots prepared by this method are usually relatively coarse, and the size distribution is not uniform, which increases the difficulty of alloy opening.
Molybdenum Rhenium sheet manufacturers tell you that compared with the vacuum melting method, the powder metallurgy method for preparing molybdenum-rhenium alloy is relatively simple, low-cost, and relatively easy to realize industrialization. Therefore, almost all products currently available for sale use powder metallurgy method. However, it is not easy to control the impurity content in the alloy ingot by powder metallurgy. Generally, the impurity content in the sintered ingot can be well controlled by vacuum smelting.
