Produkt-Beschreibung
CuNi23 (Alloy 180) Precision Resistance Wire – 0.12mm Diameter
Product Overview
CuNi23 (Alloy 180 / Cuprothal 180) precision resistance wire from Huona is a copper-nickel-manganese alloy designed for stable, mid-resistance applications requiring low temperature coefficient and good corrosion resistance. It is the industry-standard grade for wire-wound resistors, rheostats, and heating elements where a balance of resistivity, TCR, and cost is needed.
Core Specifications
- Product Name: CuNi23 (Alloy 180) Precision Resistance Wire
- Alloy Composition: Cu ~77%, Ni ~23%, Mn ~1–2%
- Diameter: 0.12mm (customizable: 0.05–1.00mm)
- Tolerance: ±0.005mm
- Form: Plastic spool (standard length: 800m/spool; custom lengths available)
- Key Electrical Properties:
- Resistivity (20°C): ~0.39 Ω·mm²/m
- Temperature Coefficient of Resistance (TCR): ±50 ppm/°C
- Maximum Operating Temperature: 300°C
- Standards Compliance: GB/T 1234, ASTM B172, DIN 17471, RoHS 2.0, REACH
- Manufacturer: Huona (Shanghai) New Material Co., Ltd.
Key Advantages
1. Stable Resistivity with Low TCR
CuNi23 (Alloy 180) offers consistent resistivity across typical operating temperatures, with a TCR of ±50 ppm/°C. This makes it ideal for applications where resistance drift must be minimized, without requiring the ultra-low TCR of more expensive precision alloys.
2. Balanced Resistivity for Compact Designs
With a resistivity of ~0.39 Ω·mm²/m, it enables the design of compact wire-wound resistors and heating elements, making it a cost-effective choice for mid-range resistance requirements.
3. Excellent Corrosion & Oxidation Resistance
The copper-nickel base forms a protective oxide layer, providing good resistance to atmospheric corrosion, moisture, and mild chemical environments. This ensures long-term reliability in industrial and consumer electronics applications.
4. Good Mechanical Strength & Formability
The wire has a tensile strength ≥400 MPa and elongation ≥25%, making it suitable for fine winding, forming, and soldering. It handles repeated bending without work-hardening excessively, supporting high-volume production.
5. Versatile & Cost-Effective
CuNi23 is widely compatible with standard soldering, welding, and insulation processes. Compared to higher-resistivity nickel-chromium alloys, it offers a more economical solution for applications that don’t require extreme operating temperatures.
