Tungsten Rhenium Wire
W-3Re/W-25Re, W-5Re/W-20Re, W-5Re/W-26Re, W/W-26Re, Commonly used for tungsten sapphire or sapphire tungsten-rhenium alloy wire for single crystal sapphire binding Model: W-25Re, diameter 0.5mm
- Description
Tungsten-rhenium alloy is mainly used for structural materials in high-temperature fields, and has a wide range of applications in electronic technology, nuclear technology, aerospace technology and temperature measurement technology.
There are three aspects that are currently the most widely used:
1. Low-rhenium alloy wire and high-rhenium alloy wire thermocouple matched to
2. Low-rhenium alloy wire and high-rhenium alloy wire thermocouple into the match, a wide temperature range (0 ~ 2500C), high values of thermoelectric power, fast response, good corrosion resistance, so in the tungsten-rhenium thermocouple wire thermometer It is widely used. It is not only used in vacuum, reducing atmosphere and inert atmosphere, but also used in oxidizing atmosphere instead of platinum-rhodium thermocouple temperature measurement when taking anti-oxidation measures.
3. Used to make single crystal sapphire for binding.
