High-Precision 6J13 Manganin Alloy Foil 0.0125*100mm
Product Overview
6J13 manganin alloy foil (0.0125mm×100mm), a ultra-thin precision resistance material independently developed by Huona New Material, is a Mn-Cu-Ni ternary alloy foil engineered for miniaturized high-precision components. Through proprietary "ultra-thin cold-rolling + vacuum annealing" technology, this foil achieves an extreme thickness of 0.0125mm (12.5μm) with ultra-tight tolerance (±0.0005mm) and uniform width of 100mm--perfectly matching the processing requirements of micro-electronic elements and pressure sensor grids.
Standard Designations & Application-Oriented Foundation
- Alloy Grade: 6J13
- Dimensional Specification: 0.0125mm (12.5μm) thickness × 100mm width (tolerance: thickness ±0.0005mm, width ±0.15mm)
- International Alignment: Performance comparable to DIN 17471 CuMn12Ni2 ultra-thin foils
- Compliant Standards: GB/T 1234-2019 + GB/T 2059-2021 + IEC 60404-8-2
- Manufacturer: Huona New Material, certified to ISO 9001 and RoHS
Key Core Advantages
1. Ultra-Thin Precision for Miniaturization
- Extreme Thickness Advantage: 0.0125mm thickness (12.5μm) is 75% thinner than conventional 0.05mm manganin strips
- Dimensional Uniformity: Thickness variation across the entire foil width (100mm) is ≤0.0003mm
2. Sensor-Specific Performance Optimization
- Stable TCR for Measurement Accuracy: TCR as low as ±8 ppm/℃ (-40℃ to 140℃)
- Flexibility for Curved Sensors: Elongation ≥28% (annealed state) enables bending to a minimum radius of 0.1mm
3. Micro-Processing Adaptability for Electronic Elements
- Ultra-Fine Etchability: Supports micro-chemical etching with line width as narrow as 0.01mm
- Clean Surface for Thin-Film Bonding: Oil-free, oxide-free surface ensures strong adhesion with substrates
