Cr10Ni90 heating wire is a high-resistance alloy wire composed of elements such as chromium and nickel. It has high resistance characteristics and high temperature stability and is widely used in various heating equipment and electric furnace heating elements. The heating wire has excellent resistance characteristics and can provide high power and fast heating response. It also has anti-oxidation properties and can remain stable in high-temperature environments. It is widely used in industrial heating equipment, home appliances, laboratory equipment, chemical industry and other fields to meet high-temperature heating needs in different scenarios.

Basic performance:

• Chemical composition: Cr10Ni90 heating wire is mainly composed of chromium (Cr) and nickel (Ni). Among them, the chromium content accounts for about 10% of the mass ratio, and the nickel content accounts for about 90% of the mass ratio.
• Physical properties: Cr10Ni90 heating wire has a high melting point, usually between 1200-1400 degrees Celsius. It has good resistivity and is capable of producing proper resistive heating. In addition, the heating wire has a low coefficient of linear expansion, which helps maintain better stability during heating and cooling.
• Mechanical properties: Cr10Ni90 heating wire has high tensile strength and yield strength, and can withstand certain mechanical stress. Its elongation is usually low, about 20% at room temperature.
