Cr20Ni80 heating wire is a commonly used nickel-chromium alloy heating element, which is widely used in the field of home appliances. This heating wire is made of about 20% chromium (Cr) and 80% nickel (Ni) as its main components, and has excellent resistance characteristics and high temperature stability.

Cr20Ni80 heating wire has reliable performance and excellent durability, and is suitable for the heating needs of various home appliances. It is widely used in household appliances such as electric water heaters, ovens, and dryers. This heating wire can quickly generate high temperatures and maintain a stable heating effect over a long period of use.

This heating wire has a high melting point and a high maximum use temperature, which can reach about 1100-1200 degrees Celsius. It has moderate resistivity and can produce appropriate resistive heating effect, quickly converting electrical energy into heat energy. In addition, Cr20Ni80 heating wire also has a low linear expansion coefficient and excellent mechanical strength, which can maintain stability and reliability in high temperature and mechanical stress environments.

Basic performance:

• Composition: Cr20Ni80 heating wire is composed of approximately 20% chromium (Cr) and 80% nickel (Ni) by weight. This alloy composition provides good electrical resistance and high-temperature stability.
• Resistivity: The resistivity of Cr20Ni80 heating wire is typically around 1.09-1.13 μΩ·m. This property determines the wire's electrical resistance and its ability to generate heat when an electric current passes through it.
• Maximum Operating Temperature: Cr20Ni80 heating wire has a high melting point and can withstand temperatures up to approximately 1100-1200 degrees Celsius (2012-2192 degrees Fahrenheit). It is suitable for applications requiring high-temperature heating.
• Density: The density of Cr20Ni80 heating wire is approximately 8.4 g/cm³.
• Coefficient of Linear Expansion: The wire has a coefficient of linear expansion of about 13-15×10^-6/°C, which means it expands or contracts slightly when subjected to temperature changes.
• Mechanical Strength: Cr20Ni80 heating wire has good mechanical strength, including tensile strength and yield strength. The tensile strength is typically in the range of 700-900 megapascals (MPa), and the yield strength is around 300-600 MPa. These properties allow the wire to withstand mechanical stress during operation.
• Elongation: The elongation of Cr20Ni80 heating wire is typically around 20-30%, indicating its ability to stretch slightly without breaking.
