Tungsten-rhenium alloy can be used to make special incandescent light bulb and high temperature electric couple. Rhenium and tungsten, iron form alloy, very high hardness, wear resistance and corrosion resistance is very strong. It has a highly selective catalytic function for many chemical reactions, so it is also commonly used as a catalyst. Used primarily as a catalyst in the petroleum industry, rhenium has high electron emission properties and is widely used in radio, television and vacuum technology. Rhenium has a very high melting point and is one of the main high-temperature instrument materials. Tungsten-rhenium thermocouple does not soften at 3100℃, adding 25% rhenium in tungsten or molybdenum alloy can increase the ductility of this alloy; Rhenium is used as a high-temperature coating on rockets and missiles, and is used in spacecraft instruments and high-temperature components such as heat shields, arc discharges, and electrical contactors.

Because of its high price, it was not until 1950 that the laboratory curiosity became an important emerging metal material. At present, rhenium is widely used in various sectors of modern industry, mainly used as petroleum industry and automobile industry catalyst, petroleum reforming catalyst, electronic industry and aerospace industry with rhenium alloy, etc.

1. Tungsten rhenium alloy can be mainly used as a catalyst in the petroleum industry

2. Rhenium has high electron emission properties and can be used in alloys for radio, television and vacuum technology.

3. Rhenium has a high melting point, is a major high temperature instrument material.

4. Rhenium and rhenium alloys can also be used as electronic tube elements and ultra-high temperature heaters to evaporate metal.

5. Tungsten-rhenium thermocouple at 3100℃ does not soften, tungsten or molybdenum alloy with 25% rhenium can increase the ductability; Rhenium is used as a high-temperature coating on rockets and missiles, and is used in spacecraft instruments and high-temperature components such as heat shields, arc discharges, and electrical contactors.

6. Metal tungsten rhenium alloy in the daily use of what can be made of tap water nib and high temperature thermocouple; In alcohol dehydrogenation, synthesis of ammonia and other chemical catalysts; Rhenium alloy can withstand high temperature; Due to the existence and dispersion of rhenium, its price is high and its practical application is still to be developed. It is also used to make electric filaments, shells for satellites and rockets, and protective plates for atomic reactors.
