Catalytic converters are probably the biggest source of recyclable platinum today, because so many of them have been manufactured – and so many are piling up in scrapyards and other places where cars are repaired or scrapped. But even though cat convertors might be the biggest source of platinum, are they the best source for speculators who like to collect platinum scrap and send it to us to be refined? Not necessarily.Read More
Did you know that some thermocouples contain gold and gold alloys? They are highly specialized, not the kind of thermocouples or thermocouple wire that you can pull out of old stoves or air conditioners. They are usually used in laboratory settings to measure low to moderate temperatures. If you acquire even a small quantity of them...Read More
Valuable and precious metals are used in many medical devices. But before we explain where those metals are used, let’s answer this question: Where can you buy scrapped medical devices? The short answer to that question is, it can be difficult to obtain large quantities of used medical devices… Still, it is possible to obtain and recycle quantities of some medical devices that can offer you a good return on your investment if you send them to us to be recycled. Let’s take a closer look.Read More
How valuable are the precious metals in a single toaster? How about in a coffee maker or a toaster oven? In reality, you won’t find more than a few cents’ worth of precious metals in small appliances like those. But when the quantities of small appliances increase, things can get more interesting – and more profitable. Here are some interesting variables that can have a big impact on the potential value of quantities of smaller appliances . . .Read More
...Yet there is a compelling reason why business brokers should slow down a little and take a close look at the businesses that they are listing for sale: Many businesses contain sources of gold and other precious metals that can be profitably recycled with a qualified precious metals refinery like ours....Read More
We’ve written about thermocouples before on this blog, and today we are going to provide you with a checklist of where to find them. But before we do, let’s get a quick overview of what they are . . .
Thermocouples, like batteries, are devices that are made up of two or more metals that generate voltage. When they are subjected to temperature changes (or radiation changes in some cases), changes occur in the amount of voltage that they generate. In fact, when one end of a long wire thermocouple is heated, that voltage increase can be measured at the other end.
So the result is that thermocouples can be used to remotely measure changes in temperature. If you’re supervising a production line, for example, thermocouples can help you monitor temperature changes from the safety of a control room that is located at some distance from the line itself. Thermocouples can also be used to ensure the safety of manufacturing operations. If the temperature in a piece of equipment rises above safe levels, for example, a device equipped with a thermocouple can automatically shut it down.
What Precious Metals Do Thermocouples Contain?
Depending on the application, they can contain a number of different precious and non-precious metals. They can be made of: pure platinum, platinum/rhodium alloys, Palladium/Platinum/Gold alloy, nickel alloys, tungsten alloys; and even a combination of 2 pure noble metals like Gold and Platinum or Platinum and Palladium.
Where Are Thermocouples Found?
- Airplane gauges and controls
- Air conditioning systems
- Chemical manufacturing plants
- Equipment used in the manufacturing of steel and other metals
- Gas turbines
- Ignition systems used in manufacturing
- Industrial safety systems
- Industrial sensors of many kinds
- Industrial valves and actuators
- Kerosene lamps and space heaters
- Medical testing and monitoring equipment
- Power plants, including nuclear power plants where thermocouples can be used to measure radiation
- Robotic and other welding equipment
- Safety cutoff values and switches
- Steam systems
- Water heaters
