Descrição de produto
6J11 New Constantan Alloy Strip
Product Overview

6J11 new constantan alloy strip is a high-performance precision resistance alloy product independently developed by Huona New Material. This copper-nickel-manganese (Cu-Ni-Mn) based alloy is optimized for medium-temperature precision applications through advanced vacuum smelting, multi-pass precision cold-rolling, and controlled atmosphere annealing processes.

Key characteristics include:

  • Stable electrical and mechanical properties within 0-120℃ operating range
  • Density of 8.5g/cm³ and resistivity of 0.49μΩ*m
  • Low resistance temperature coefficient (TCR)
  • Excellent corrosion resistance and superior processing performance
  • Ideal for precision resistors, current shunts, and strain gauges in consumer electronics, industrial control, and automotive systems
Standard Designations & Material Foundation
  • Alloy Grade: 6J11 (Chinese standard new constantan alloy grade)
  • International Equivalents: Comparable to DIN 17471 CuNi44Mn1.5 and ASTM B193 modified constantan
  • Core Parameters: 0-120℃ operating range; density 8.5g/cm³; resistivity 0.49μΩ*m (20℃)
  • Compliant Standards: GB/T 1234-2019, IEC 60404-8-2, and RoHS 2.0
  • Manufacturer: Huona New Material (ISO 9001 and ISO 14001 certified)
Key Advantages
1. Stable Electrical Performance in Medium-Temperature Range
  • Resistivity stably maintained at 0.49μΩ*m (20℃)
  • TCR as low as ±15 ppm/℃ (0-120℃ range)
  • Resistance drift <0.008% after 1000 hours at 120℃
2. Balanced Mechanical & Processing Performance
  • Density of 8.5g/cm³ (12% lower than nickel-chromium alloys)
  • Tensile strength 480-550 MPa (annealed state)
  • Elongation ≥25% with 180° bending capability
3. Reliable Corrosion & Environmental Adaptability
  • Passes 1000-hour ASTM B117 salt spray testing
  • Low thermoelectric potential (≤2μV/℃ vs. copper)
  • Resists atmospheric corrosion, freshwater, and mild chemical environments
