Product Description
CuMn8Ni Manganin Wire (0.8mm Diameter)
Product Overview
CuMn8Ni manganin wire (0.8mm diameter) from Huona New Material is a high-precision copper-manganese-nickel alloy wire with a bright, uniform surface finish as shown. Composed of Cu (balance) + 7.0–9.0% Mn + 1.0–2.0% Ni with trace stabilizing elements, it is produced via vacuum smelting, hot rolling, multi-pass precision drawing, and controlled annealing. It features ultra-low temperature coefficient of resistance (TCR), stable resistivity, and excellent mechanical ductility, making it ideal for precision wirewound resistors, current shunts, strain gauges, and high-frequency signal components requiring long-term stability and reliable performance.
Standard Designations & Core Material Foundation
- Alloy Grade: CuMn8Ni
- International Equivalents:
- UNS: C18500
- DIN: 2.0870
- JIS: C1850
- GB/T: 3131-2019 (Mn8Ni)
- Key Specification: 0.8mm diameter (tolerance: ±0.005mm); soft/half-hard/hard temper available
- Chemical Composition (wt%): Mn: 7.0–9.0%; Ni: 1.0–2.0%; Cu: balance; Fe ≤0.3%; Pb ≤0.05%; C ≤0.1%

- Manufacturer: Huona New Material, certified to ISO 9001 and ISO 14001
Key Core Advantages (Centered on 0.8mm Fine Wire)
1. Ultra-Stable Electrical Performance
- Low TCR & Stable Resistivity: Resistivity = 0.30 μΩ·m (20℃), TCR = ±8×10⁻⁶/℃ (0–100℃), ensuring resistance drift ≤0.008%/℃—critical for precision measurement and control circuits.
- Low Signal Attenuation: 0.8mm diameter balances conductivity and flexibility, minimizing signal loss in high-frequency and precision sensing applications.
2. Excellent Mechanical & Processing Properties
- High Ductility & Flexibility: Tensile strength ≥400 MPa (hard temper) / ≥280 MPa (soft temper), elongation ≥25% (soft temper), supporting tight winding (minimum radius ≥1.6mm) and complex forming without breaking.
- Bright Surface & Good Solderability: Polished bright finish (Ra ≤0.6μm) ensures low contact resistance and reliable soldering, ideal for resistor winding and terminal connections.
3. Good Corrosion & Environmental Resistance
- Atmospheric & Mild Corrosion Resistance: Forms a dense oxide film, passes 500-hour ASTM B117 salt spray test without obvious corrosion.
- Wide Operating Temperature: -40℃ to 130℃, stable performance in industrial, automotive, and electronic equipment environments.
