Descrição de produto
Huona High Electrical Conductivity 6J12 Manganin Alloy Strip 0.19mm Thickness × 100mm Width
Product Overview

6J12 manganin alloy strip (0.19mm×100mm), a high-precision resistance alloy product independently developed and manufactured by Huona New Material, is a typical manganese-copper (Mn-Cu) based precision resistance alloy. Crafted via our advanced vacuum smelting, cold-rolling, and precision annealing processes, this strip features a fixed thin gauge of 0.19mm and standard width of 100mm, achieving ultra-tight dimensional tolerances and consistent electrical properties.

Standard Designations & Material Foundation
  • Alloy Grade: 6J12 (Chinese standard manganin precision resistance alloy grade; belongs to Mn-Cu series)
  • International Equivalents: Similar to DIN 17471 CuMn12Ni2, ASTM B193 Manganin, UNS C75400 (for high-precision resistance scenarios)
  • Dimensional Specification: 0.19mm thickness (tolerance: ±0.002mm) × 100mm width (tolerance: ±0.1mm)
  • Compliant Standards: Adheres to GB/T 1234-2019 (Chinese standard for resistance alloy strips), IEC 60404-8-2, and JIS H3530
  • Manufacturer: Huona New Material, certified to ISO 9001 and RoHS, with 20+ years of experience in manganin alloy smelting and precision processing
Key Advantages
  • Extreme Resistance Stability: Temperature coefficient of resistance (TCR) as low as ±5 ppm/°C (-50℃ to 150℃)
  • Optimized Thin-Gauge Mechanical Balance: 0.19mm thickness strikes perfect balance between miniaturization and processability
  • Standard Width for Efficient Batch Production: 100mm width matches industrial precision etching and stamping die sizes
  • Superior Corrosion & Current Stability: Resists atmospheric corrosion, freshwater, and mild chemical environments
  • Excellent Etchability for Precision Patterns: Minimum etched line width up to 0.03mm

Product Specifications
Item Specification
Surface Finish Bright annealed (oxide-free, oil-free) - optimal for precision etching; matte finish (customizable for anti-glare needs)
Flatness ≤0.05mm/m - ensures uniform thickness during etching and stamping, avoiding resistance deviation
Machinability Excellent - compatible with CNC stamping, laser cutting, and chemical etching; no edge burrs after processing
Weldability Suitable for spot welding and TIG welding - welded joints have resistance variation ≤0.1%
Insulation Compatibility Compatible with polyimide (PI) and epoxy resin films for resistor substrate bonding
Packaging Vacuum-sealed in anti-oxidation aluminum foil bags with desiccants; wooden spools (150mm diameter) to prevent strip warping and oxidation
Customization Temper adjustment (soft/half-hard/hard) for specific forming requirements; width slitting (minimum 5mm); anti-tarnish coating (passivation treatment)
Typical Applications
  • High-Precision Current Shunts: Used in ammeters, power analyzers, and EV battery management systems (BMS)
  • Standard Resistors & Calibration Components: As the core material of laboratory standard resistors and calibration equipment
  • Precision Measuring Instruments: Resistance elements for pressure transducers, torque sensors, and flow meters
  • Consumer Electronics: Micro-shunts for smartphone fast-charging modules and laptop power adapters
  • Industrial Control Systems: Current-sensing resistors for frequency converters, programmable logic controllers (PLC), and servo drives
