CuNi19 NC025 Alloy Insulated Heating Wire with FEP Insulation for High-Temperature Environments and Electrical Safety
CuNi19 NC025 alloy material insulated FEP heating wire is a high-performance heating wire designed for precision applications. Made from CuNi19 NC025 (Copper-Nickel alloy), it offers excellent electrical resistance, corrosion resistance, and thermal stability. The wire is insulated with FEP (Fluorinated Ethylene Propylene), providing superior heat resistance, chemical resistance, and durability in harsh environments. This heating wire is commonly used in industrial heating systems, medical devices, and automotive applications. Its consistent performance, flexibility, and long lifespan make it ideal for applications requiring precise temperature control. The combination of CuNi19 NC025 alloy and FEP insulation ensures reliable operation under high temperatures while maintaining electrical safety.
