PTC Alloy wire has medium resistivity and high positive temperature coefficient of resistance. It is widely used in various heaters. It can automatically control temperature and adjust power by keeping constant current and limiting current. PTC alloy has many advantages such as automatic temperature control, automatic power regulation, constant current, current limiting, energy saving and long practical life.

The Nickel-Chrome & Nickel-Chrome-Iron alloy wires are widely used as the high resistance alloy for electrical heating and wire-wound resistors in metallurgical industry, chemical industry and electrical industry, etc.
This alloy wire has higher electrical resistance coefficient, good anti-oxidation and anti-corrosion performance, and it also has good mechanical workability and weldability, with a high strength at high temperature.

Nickel 200 is the most widely used standard grades of commercially available pure brought Nickel along with and Nickel 201. These alloys offer good thermal conductivity, mechanical properties, resistance against many corrosive environments, in particular against caustic alkalis, low electrical resistivity, and good magnetostrictive properties.
Nickel 200 is easily workable by forming and drawing. Nickel 201 is a low carbon variation of Ni200 and has a very low work hardening rate which allows it to be easily cold formed. It also offers better creep resistance and is preferred over Ni200 for applications that experience temperatures over 600°F (315°C).

Fe-CuNi thermocouple (type J) is also named Fe- Constantan thermocouple. The positive leg Fe(JP) is made by pure Iron, and the main chemical composition of negative leg Constantan (JN) is Cu: Ni≈ 55%: 45%. Although they are all called Constantan, JN does not give the same EMF output curve as EN and TN, it cannot be instead by other Constantan.
