Nickel-Chromium Alloy Electroloy / Alloy C/ Resistohm60 /NiCr6015 Rod 3.0mm 2.5mm 5.5mm 8mm Used For Heat Exchangers

Chemical Composition

• It mainly consists of nickel (Ni), chromium (Cr), and iron (Fe), along with small amounts of other elements such as carbon (C), silicon (Si), manganese (Mn), cobalt (Co), sulfur (S), and phosphorus (P). Typically, the nickel content is approximately 55%-61%, and the chromium content is about 15%-18%

Physical Properties

• Resistivity: At 20℃, it has a resistivity of around 1.12 μΩ·m, enabling it to generate sufficient heat when current passes through, making it suitable for manufacturing various resistance elements.
• Density: With a density of about 8.2 g/cm³, it provides a certain weight and mass characteristics to the wire.
• Thermal Conductivity: Having a thermal conductivity of 45.2 kJ/m·h·℃, it allows for efficient heat transfer and dissipation, facilitating rapid heat exchange during heating and cooling processes.
• Coefficient of Thermal Expansion: The coefficient of thermal expansion is 17.0×10⁻⁶/℃, meaning its size changes relatively slightly with temperature variations. This is crucial for applications requiring stable performance at different temperatures, like heating elements in high-temperature furnaces.
• Melting Point: It has a relatively high melting point of about 1390℃, allowing it to remain solid in high-temperature environments and ensuring reliability in high-temperature applications.
