Product Details

NiCr Series

Nichrome wire is a type of alloy that is composed primarily of nickel, chromium, and iron. One of the key properties of nichrome wire is its high resistivity, which means that it is able to resist the flow of electrical current. Another important feature of nichrome wire is its good oxidation resistance, which allows it to withstand high temperatures and prevents it from corroding over time.

 

In addition to its high resistivity and good oxidation resistance, nichrome wire also has excellent ductility after use and weldability. This means that it can be easily shaped and formed into various shapes and sizes, and can be easily welded together to form larger structures.

 

Given these properties, nichrome wire is widely used in a variety of applications. It is commonly used to manufacture heating elements for laboratory and industrial electric furnaces, as well as various electrical devices that require thermal action, such as heat guns and industrial hair dryers. Nichrome wire is also used in water heating systems, high-value electrical resistors, heating cords, and cables.

 

Overall, nichrome wire is a versatile and reliable material that is essential in many industries. Its unique combination of properties makes it an ideal choice for applications that require high-temperature resistance, electrical resistance, and ductility.
