High Heat Equals High Value
If you’ve read this blog before, you know that we have written posts about thermocouples – those fascinating devices, made up of two different metals that are used to monitor temperatures remotely. We have also written about the probes, attached to the ends of thermocouple wires, which are used to monitor temperatures in medical testing and manufacturing processes.
Those devices often contain precious metals. But today we would like to tell you about some items that are just a bit different…
Thermocouples and probes that are used to monitor extremely high temperatures
We are not talking about the more common thermocouple set-ups that are used to monitor temperatures in water heaters, kitchen stoves, air conditioners, or pasteurizing operations. We are talking about specialized thermocouples from nuclear power plants, non-nuclear-power plants, jet engines, gas turbines, and other places where there is a need to monitor sustained levels of extremely high temperatures.
Certain precious metals and platinum alloys are used in places like those because they will not oxidize, even at extremely high temperatures. Where lesser metals would fizzle out, they keep on monitoring.
What Metals Can You Find in High-Temperature Thermocouples and Probes?
Let’s take a look at what these high-temp thermocouples can contain.
- Molybdenum – This is one tough metal. It holds up in temperatures up to 4000°F.
- Platinum-Rhodium Alloys – Used in applications up to about 3000°F.
- Tantalum – Used in applications up to about 4000°F.
- Platinum-Molybdenum Alloys – Used in application up to about 3000°F.
How Can You Determine the Value of High-Temperature Thermocouples and Probes?
If you have scrap from high-temperature applications, don’t hesitate to find out how much it can be worth. If you call us at 800-426-2344, one of our expert consultants can explain how simple it is to send in a sample of your scrap for testing.
