Product Description
Huona 6J25 Precision Resistance Alloy Plate For Manganin Shunts
Product Overview
6J25 precision resistance alloy plate is a high-performance manganese-copper-based precision resistance material independently developed by Huona New Material. This plate features stable chemical composition with core performance advantages including high resistivity, low temperature coefficient of resistance (TCR), and excellent mechanical processability. Available in customizable thicknesses (0.1-5.0mm) and widths (10-300mm), it is widely used in precision resistors, current shunts, and strain gauge components across industrial instrumentation, automotive electronics, and precision measuring equipment.
Core Parameters
- Classification: Manganese-copper alloy
- Brand: 6J25
- Chemical Composition (wt%): Cu (balance), Mn 11.5-12.5%, Fe ≤0.05%, other impurities (Al/Pb/Si/So) ≤0.02%
- Key Performance (20℃):
- Resistivity: 0.90±0.03 μΩ*m
- Applicable Temperature: 10-80℃
- TCR: -20~20×10⁻⁶/℃
- Thermoelectric Potential (vs Cu): 1 μV/℃
- Melting Point: 970℃
- Density: 8.5 g/cm³
Key Advantages
1. Excellent Electrical Stability
- High & Stable Resistivity: 0.90μΩ*m enables smaller volume of high-resistance components, critical for miniaturized electronic devices
- Low TCR: Ensures resistance drift ≤0.02% within 10-80℃, meeting precision requirements of high-stability resistors and current shunts
2. Good Mechanical & Processing Performance
- Mechanical Properties: Tensile strength ≥600 MPa, elongation ≥15% (annealed state) enables stamping, bending, and etching processes
- Corrosion Resistance: Resists atmospheric corrosion and mild chemical environments (pH 4-10), passing 500-hour ASTM B117 salt spray testing
3. Cost-Effective & Application Flexibility
- Balanced Performance-Cost Ratio: Lower raw material costs than nickel-chromium-based resistance alloys while maintaining high performance
- Customizable Specifications: Supports thickness (0.1-5.0mm) and width (10-300mm) customization for various component requirements
Typical Applications
- Precision Resistors: Used in high-resistance resistor networks for industrial frequency converters and PLC control systems
- Current Shunts: Applied in high-current shunts for power meters and EV battery management systems
- Strain Gauges: Core material for low-temperature strain gauges (10-80℃) in mechanical stress testing equipment
