The RTD wire is a pure material, typically platinum, nickel, or copper. The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature. As RTD elements are fragile, they are often housed in protective probes.
Thermostats run on either line voltage or low voltage. The easiest way to tell if you need a line or low voltage thermostat is to look at the wire. If it's a very thin wire (like a doorbell or speaker wire), you'll need a low voltage thermostat. If it's a heavy wire, you'll need a

In low temperature constructions, Teflon insulated nickel or silver plated copper wire is used along with an epoxy seal. This construction is usually limited to 400 to 500°F. High temperature constructions typically use fiberglass insulated, nickel plated copper wire and a ceramic cement which has a maximum temperature of 900°F to 1200°F.
Band heaters use electric heating elements (NiCr wire) to heat-up the external surface of drums or pipes for a gradual heat transfer. Band heating is an indirect form of industrial heating and offers safety when heating volatile and explosive substances as well as pipes or containers that cannot otherwise be heated using direct heating methods.
Material for High Temperature Gaskets. High Temperature Gasket material is necessary for applications that will have continuous temperatures exceeding +750F. Applications with intense heat, high pressure, saturated steam or hot oils can quickly lead to gasket failure if the wrong material is designated for use.
Temperatures can reach as high as 500 degrees F and use the high quality magnesium oxide that is also used in tubular heating elements that allow for effective heat transfer. Finned strip heaters are a fairly inexpensive way of heating small areas and are an excellent solution to meet any budget.

Many households, especially in rural areas, use propane as a main home heating energy source. Typical propane gas tanks are located outside, either installed on top of a concrete foundation or placed in an underground hole.
And whether ignition wire is copper, aluminum, or copper clad aluminum. There are 6,974 ignition wire suppliers, mainly located in Asia. The top supplying country is China (Mainland), which supply 100% of ignition wire respectively. Ignition wire products are most popular in
Nickel 200 – Nickel 200 alloy is a commercially pure nickel that exhibits good corrosion resistance. It is It is ferromagnetic and has relatively low electrical resistivity.
Nitinol, the non-brand-specific name, comes in an as-drawn form, which is what a Maker would want, because it allows one to set the memory. As-drawn refers to the drawing (not picture drawing) process, which is how a bar of alloy is continually pulled through reduced sized openings until it is a wire.
High temp wire, including thermocouple wire, is stocked since many internal and external wiring applications are used in environments exceeding 150°C, and even up to 200°C. We carry high temperature wire in a wide variety of materials and configurations to suit every application.
Because of pure nickel's corrosion resistance, particularly to various reducing chemicals and especially to caustic alkalis, nickel is used to maintain product quality in many chemical reactions, particularly the processing of foods and synthetic fibre manufacture.
