Product Description
6J13 Manganin Alloy Foil (0.0125mm Thickness × 100mm Width)
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. It integrates ultra-low resistance temperature coefficient (TCR), excellent flexibility, and superior micro-etchability—becoming the core material for ultra-miniature resistors, strain
gauge grids in pressure sensors, and thin-film resistance elements
in high-density electronic devices.
Standard Designations & Application-Oriented Foundation
- 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,
with adjusted Ni-Mn ratio to prevent brittle fracture during
ultra-thin rolling
- Compliant Standards: GB/T 1234-2019 (resistance alloy strips/foils) + GB/T 2059-2021
(copper alloy foils) + IEC 60404-8-2 (precision resistance
components for sensors)
- Manufacturer: Huona New Material, certified to ISO 9001 and RoHS, with
specialized ultra-thin foil production lines (minimum rolling
thickness 0.005mm)
Key Core Advantages (Tailored for 0.0125×100mm & Sensor/Electronic
Applications)
1. Ultra-Thin Precision for Miniaturization
- Extreme Thickness Advantage: 0.0125mm thickness (12.5μm) is 75% thinner than conventional
0.05mm manganin strips, enabling component volume reduction by
60%—critical for ultra-slim electronic devices (e.g., foldable
phone sensors) and micro-pressure transducers (where space between
sensing layers is ≤20μm).
- Dimensional Uniformity: Thickness variation across the entire foil width (100mm) is
≤0.0003mm, ensuring resistance consistency ±0.03% for
micro-resistors—avoiding signal drift in pressure sensors caused by
uneven thickness.
2. Sensor-Specific Performance Optimization
- Stable TCR for Measurement Accuracy: TCR as low as ±8 ppm/℃ (-40℃ to 140℃), perfectly matching the
operating temperature range of industrial pressure sensors (-20℃ to
120℃). Resistance drift <0.006% after 2000 hours of continuous
operation at 80℃—ensuring pressure measurement error ≤0.1% FS (full
scale).
- Flexibility for Curved Sensors: Elongation ≥28% (annealed state) enables bending to a minimum
radius of 0.1mm (8× thickness) without cracking—ideal for curved
pressure sensor diaphragms (e.g., automotive tire pressure sensors)
and flexible electronic components.
3. Micro-Processing Adaptability for Electronic Elements
- Ultra-Fine Etchability: Uniform microstructure (grain size ≤15μm) and bright annealed
surface (Ra ≤0.1μm) support micro-chemical etching with line width
as narrow as 0.01mm—meeting the production of high-density resistor
arrays in integrated circuits and strain gauge grids in precision
pressure sensors.
- Clean Surface for Thin-Film Bonding: Oil-free, oxide-free surface (verified via XPS analysis) ensures
strong adhesion with polyimide (PI) and epoxy substrates (peel
strength ≥0.8 N/mm)—critical for sensor foil-substrate bonding
without delamination.
