उत्पाद विवरण
Ultra-Thin In-Stock CuNi44 Foil 0.0125mm Thick x 102mm Wide High Precision & Corrosion Resistance
Product Description
CuNi44 Foil (0.0125mm Thickness × 102mm Width)
Product Overview

CuNi44 foil (0.0125mm × 102mm), this copper-nickel resistance alloy, also known as constantan, is characterized by a high electrical resistance coupled with a fairly small temperature coefficient of the resistance. This alloy also shows high tensile strength and resistance towards corrosion. It can be used at temperatures of up to 600°C in air.

Standard Designations
  • Alloy Grade: CuNi44 (Copper-Nickel 44)
  • UNS Number: C71500
  • International Standards: Complies with DIN 17664, ASTM B122, and GB/T 2059
  • Dimensional Specification: 0.0125mm thickness × 102mm width
  • Manufacturer: Huona New Material, certified to ISO 9001 for precision alloy processing
Key Advantages (vs. Standard CuNi44 Foils)

This 0.0125mm × 102mm CuNi44 foil stands out for its targeted ultra-thin and fixed-width design:

  • Ultra-Thin Precision: 0.0125mm thickness (equivalent to 12.5μm) achieves industry-leading thinness, enabling miniaturization of electronic components without sacrificing mechanical strength.
  • Stable Resistance Performance: Resistivity of 49 ± 2 μΩ*cm at 20°C and low temperature coefficient of resistance (TCR: ±40 ppm/°C, -50°C to 150°C)--ensures minimal resistance drift in high-precision measurement scenarios, outperforming thinner non-alloy foils.
  • Strict Dimensional Control: Thickness tolerance of ±0.0005mm and width tolerance of ±0.1mm (102mm fixed width) eliminate material waste in automated production lines, reducing post-processing costs for customers.
  • Excellent Formability: High ductility (elongation ≥25% in annealed state) allows for complex micro-stamping and etching (e.g., fine resistor grids) without cracking--critical for precision electronic manufacturing.
  • Corrosion Resistance: Passes 500-hour ASTM B117 salt spray testing with minimal oxidation, ensuring long-term reliability in humid or mild chemical environments.

Typical Applications
  • Micro-Electronics: Thin-film resistors, current shunts, and potentiometer elements in wearable devices, smartphones, and IoT sensors (0.0125mm thickness enables compact PCB design).
  • Strain Gauges: High-precision strain gauge grids (102mm width fits standard gauge manufacturing panels) for load cells and structural stress monitoring.
  • Medical Devices: Miniature heating elements and sensor components in implantable devices and portable diagnostic tools (corrosion resistance ensures biocompatibility with body fluids).
  • Aerospace Instrumentation: Precision resistance components in avionics (stable performance under temperature fluctuations at high altitudes).
  • Flexible Electronics: Conductive layers in flexible PCBs and foldable displays (ductility supports repeated bending).
Huona New Material implements rigorous quality control for this ultra-thin CuNi44 foil: each batch undergoes thickness measurement (via laser micrometer), chemical composition analysis (XRF), and resistance stability testing. Free samples (100mm × 102mm) and detailed material test reports (MTR) are available upon request. Our technical team provides tailored support--including etching parameter recommendations and anti-oxidation storage guidelines--to help customers maximize the performance of this precision foil in micro-manufacturing scenarios.
