The maximum operating temperature of TK240 alloy can reach 1150℃, with good oxidation resistance, good corrosion resistance (except sulfur-containing and specific atmospheres), and strong deformation resistance during use. Open coil heating elements can be used

Chemical Composition and Propertes:

Nickel-chrome wire, also known as nichrome wire, is a type of resistance wire that is commonly used in heating applications due to its unique properties.

Key features and characteristics of nickel-chrome wire:

1. Composition:

   • Nickel-chrome wire is typically composed of an alloy containing approximately 40% nickel and 20% chromium.
   • The specific nickel-to-chromium ratio can vary slightly depending on the application requirements.

2. High-Temperature Resistance:

   • Nickel-chrome wire has an exceptionally high melting point, typically ranging from 1,400°C to 1,500°C.
   • This high-temperature resistance allows the wire to operate reliably in environments with elevated temperatures.

3. Electrical Resistivity:

   • Nickel-chrome wire exhibits a relatively high electrical resistivity, usually around 1.00-1.10 microhm-cm at room temperature.
   • This property enables the wire to efficiently convert electrical energy into heat, making it suitable for use as a heating element.

4. Oxidation Resistance:

   • The chromium content in the nickel-chrome alloy forms a protective oxide layer on the surface, providing excellent resistance to oxidation at high temperatures.
   • This oxidation resistance helps maintain the wire's structural integrity and electrical properties over extended periods of use.

5. Mechanical Strength:

   • Nickel-chrome wire has good mechanical strength and hardness, allowing it to maintain its structural integrity under the stresses of high-temperature applications.
   • This mechanical strength is important for applications where the wire is subjected to vibrations or physical stresses.

6. Applications:

   • Nickel-chrome wire is widely used in a variety of heating applications, including:
     • Electric heating elements (e.g., ovens, furnaces, toasters)
     • Industrial heaters and furnaces
     • Heating coils in HVAC systems
     • Heating tapes and cables for industrial and commercial use
     • Heating elements in household appliances

7. Fabrication and Handling:

   • Nickel-chrome wire is typically produced through processes like wire drawing or rolling.
   • Special care must be taken during the handling and installation of nickel-chrome wire to avoid mechanical damage, as the alloy can be brittle.

The combination of high-temperature resistance, electrical properties, and oxidation resistance make nickel-chrome wire a popular choice for resistance heating applications where reliable and efficient heating is required. Its ability to operate at high temperatures while maintaining its structural and electrical characteristics is a key factor in its widespread use across various industries.
