Heat-Resistant Electric Thermal Alloy Wire Nickel-Chromium Resistance Wire 12-14 W/M·K Cr20Ni35 Wire
Product Introduction
Cr15Ni60 Wire has a wide range of applications in the field of electrical components, mainly due to its excellent resistance performance and high temperature stability. The main components of this alloy include 15% chromium (Cr) and 60% nickel (Ni), and the combination of these components makes it perform well in high temperature and corrosive environments. The physical properties of Cr15Ni60 Wire include density 8.2 g/cm³, resistivity of about 1.11±0.05 μΩ・m at 20°C, melting point of about 1390℃, and thermal conductivity of about 45.2 KJ/m・h℃.
In terms of electrical components, Cr15Ni60 Wire is widely used to manufacture various resistance components such as resistors, potentiometers, thermistors, etc. Its high resistivity and stable resistance characteristics enable it to generate stable heat when current passes through it, while maintaining good corrosion resistance and oxidation resistance, ensuring the reliability and safety of the equipment in long-term use. In addition, the resistance temperature coefficient of Cr15Ni60 Wire is small, which means that in a wide temperature range, the change of resistance value is very small, so its resistance value has high stability, which is particularly suitable for precision instruments and constant temperature electric heating elements.
