Product Introduction
Cr20Ni30 Wire is a high resistance electric heating alloy wire, mainly composed of 20% chromium (Cr) and 30% nickel (Ni), with excellent corrosion resistance, oxidation resistance and high temperature stability.
Resistivity: about 1.04±0.05μΩ·m (20℃) at room temperature. Density: 7.90 g/cm³. Melting point: above 1400℃. Thermal conductivity: 11.3 W/(m·K).
Cr20Ni30 Wire is widely used in electric heating elements, furnace heating elements, electric furnace lining materials, electronic components and other fields. Its excellent high temperature oxidation resistance and resistance characteristics make it the preferred material for electric heating equipment. In addition, it is also suitable for thermocouples, industrial heaters, resistors, chemical equipment, vacuum equipment and aerospace fields.
