Information

Rhenium crucible manufacturers tell you that due to the excellent properties mentioned above, rhenium has become an important material used in many fields. In the metallurgical industry, rhenium is used as an alloying element to improve the properties of the alloy. For example, pure tungsten and pure molybdenum become brittle as glass at lower temperatures, making them difficult to process and thus limited in use. However, tungsten-rhenium alloys or molybdenum-rhenium alloys made by adding appropriate amount of rhenium to tungsten or molybdenum have good plasticity and can be processed into various structural materials, while maintaining high hardness, high strength and high temperature resistance. Many parts of American manned spacecraft are made of this rhenium alloy. The rhenium crucible manufacturer tells you that adding a small amount of rhenium to the chromium-nickel alloy can greatly improve the melting point and strength of the alloy. The service life of parts made of this alloy can be extended several times to dozens of times.

The rhenium crucible manufacturer tells you that rhenium is mainly used as a catalyst in the petroleum industry, and as an element additive in superalloys and superalloys. Pure rhenium products can be used for high-temperature parts in particularly harsh working atmospheres. Rhenium plating on metals such as tungsten for space technology increases wear and corrosion resistance. Rhenium filament or rhenium-coated tungsten filament is used as the filament and cathode of electron tubes and is more durable than tungsten filament in argon or nitrogen containing trace amounts of moisture. The rhenium crucible manufacturer tells you that rhenium has high temperature stability and strong anti-corrosion ability under the action of an arc, so rhenium tungsten alloy can be used for the working part of electrical contacts, and its performance can be compared with platinum and ruthenium products.
Rhenium has high electron emission properties and is widely used in radio, television and vacuum technology. The rhenium crucible manufacturer tells you that rhenium has a very high melting point and is a major high-temperature instrument material. Tungsten-rhenium thermocouples do not soften at 3100°C. Alloying tungsten or molybdenum with rhenium increases ductility. Alloys of rhenium and rhenium can also be used as electronic tube components and ultra-high temperature heaters to vaporize metals. Rhenium is used as a high-temperature coating on rockets and missiles. Instruments and high-temperature components used in spacecraft such as heat shields, arc discharges, and electrical contactors require rhenium.
