Product Description
Eureka Enameled Wire (0.516mm, 180°C Class)
Product Overview
Eureka enameled wire (0.516mm diameter, 180°C class) from Huona New Material is a high-performance resistance wire composed of 60% copper and 40% nickel (CuNi40). Engineered through vacuum smelting, precision drawing, and high-temperature enamel coating, this wire combines extremely stable electrical resistivity, low temperature coefficient of resistance (TCR), and excellent thermal stability up to 180°C. The 0.516mm diameter ensures a balance of mechanical strength and flexibility, making it ideal for high-precision resistors, current shunts, and heating elements in automotive electronics, industrial control systems, and aerospace applications.
Standard Designations & Core Material Foundation
- Alloy Grade: Eureka (CuNi40; equivalent to UNS C18400, DIN 2.0872)
- Key Specification: 0.516mm bare diameter (tolerance: ±0.003mm)
- Insulation Class: 180°C (Polyesterimide or Polyamide-imide enamel coating)
- Chemical Composition: Cu: 59-61%; Ni: 39-41%; trace impurities ≤0.5%
- Compliant Standards: IEC 60317, NEMA MW 1000, GB/T 6109
- Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949
Key Core Advantages (Centered on 0.516mm & 180°C Performance)
1. Ultra-Stable Electrical Performance
- High & Stable Resistivity: Exhibits a resistivity of 0.49 μΩ·m (20°C), which is significantly higher than pure copper, allowing for compact resistor designs.
- Ultra-Low TCR: The temperature coefficient of resistance is as low as ±40 ppm/°C (0-100°C), ensuring minimal resistance drift (≤0.004%/°C) even under fluctuating temperatures. This stability is critical for precision current sensing and voltage regulation.
2. Superior 180°C Thermal Endurance
- Continuous High-Temperature Operation: The enamel insulation is rated for continuous use at 180°C, with a short-term overload capability up to 200°C.
- Thermal Shock Resistance: The enamel coating maintains adhesion and dielectric strength even after 10,000 hours of aging at 180°C, far exceeding the performance of standard 155°C class wires.
3. Optimized 0.516mm Mechanical & Process Properties
- Balanced Strength & Flexibility: The 0.516mm diameter provides a tensile strength of ≥550 MPa (hard drawn) while maintaining sufficient ductility for winding on small mandrels (minimum bending radius ≥2× diameter).
- Excellent Solderability: The enamel layer is designed for easy stripping or direct soldering (depending on coating type), facilitating high-speed automated assembly in resistor manufacturing.
