Product Description
Huona 0.19*25mm 6J13 Manganin Alloy Strip Ultra-Stable Resistivity
6J13 Manganin Alloy Strip (0.19mm Thickness × 25mm Width)
6J13 manganin alloy strip (0.19mm×25mm), a precision-engineered resistance alloy product from Huona New Material, is a thin-gauge functional strip crafted from Mn-Cu-Ni ternary manganin alloy. Through advanced vacuum smelting, multi-pass precision cold-rolling, and segmented annealing processes, this strip achieves ultra-tight dimensional control (0.19mm thickness ±0.002mm, 25mm width ±0.1mm) and consistent electrical properties.
Standard Designations & Specification Value
- Alloy Grade: 6J13 (Chinese standard manganin precision resistance alloy; optimized for thin-gauge rolling performance)
- Dimensional Specification: 0.19mm thickness × 25mm width (customizable, but this fixed 规格 matches mainstream micro-component stamping dies)
- International Alignment: Performance aligned with DIN 17471 CuMn12Ni2 thin strips, with adjusted Mn content (12.0-13.0%) to enhance thin-gauge ductility
- Compliant Standards: GB/T 1234-2019 (resistance alloy strips) + GB/T 2059-2021 (copper alloy strips) + IEC 60404-8-2 (precision resistance components)
- Manufacturer: Huona New Material, certified to ISO 9001 and RoHS, with specialized thin-gauge alloy rolling lines (minimum rolling thickness 0.01mm)
Key Advantages (Tailored for 0.19×25mm Specification)
1. Specification-Matched Micro-Component Adaptability
- Thickness Precision for Miniaturization: 0.19mm thickness hits the "golden balance" for micro-devices--thinner than 0.25mm strips (reducing component volume by 24%) while avoiding the brittleness of ultra-thin strips (<0.15mm) that crack during stamping.
- Narrow Width for Batch Stamping: 25mm width matches 4-6 sets of micro-shunt stamping dies (each die size ~4mm) per strip, enabling one-time stamping of 2000+ micro-components per 100m strip--reducing material waste by 30% vs. using 50mm wide strips for small parts.
2. Enhanced Micro-Processing Performance
- Ultra-Fine Etchability: The strip's uniform microstructure (grain size ≤20μm) and bright annealed surface (Ra ≤0.15μm) support ultra-fine chemical etching--minimum etched line width up to 0.02mm.
- Stable Stamping Consistency: After 5000 times of continuous stamping (simulating mass production), the strip's thickness variation is <0.001mm, and the resistance deviation of stamped components is ≤0.05%.
3. Cost-Efficiency & Application Flexibility
- Material-Saving Design: The fixed 25mm narrow width eliminates secondary slitting (a common step for wide strips), reducing processing costs by 18% and shortening delivery cycles by 3-5 days.
- Dual-Temper Optional: Offers both soft (annealed, elongation ≥25%) and half-hard (elongation 15-20%) tempers for different processes.
Technical Specifications
| Attribute | Value (Typical) | Micro-Application Significance |
|---|---|---|
| Chemical Composition (wt%) | Cu: 82.0-86.0%; Mn: 12.0-13.0%; Ni: 2.0-3.0%; Fe: ≤0.5% | Mn content optimized to prevent thin-gauge cracking during rolling |
| Thickness | 0.19mm (tolerance: ±0.002mm) | Ensures uniform resistance of micro-shunts (avoiding current bias) |
| Width | 25mm (tolerance: ±0.1mm) | Matches 4-6 sets of micro-dies for batch stamping |
| Resistivity (20℃) | 0.44±0.04 μΩ*m | Balanced for 1-5A micro-shunts (common in consumer electronics) |
| TCR (-40℃ to 140℃) | ±10 ppm/℃ | Stable for consumer electronics (operating temp: -10℃ to 60℃) |
Typical Micro-Application Scenarios
- Consumer Electronics Fast-Charging: Micro-current shunts for 65W smartphone chargers (0.19mm thickness fits the charger's slim design, 25mm width supports batch stamping of 4 shunts per strip).
- Wearable Health Sensors: Resistance elements for smart watch heart rate sensors (soft temper enables 0.38mm radius bending, narrow 25mm width reduces material waste).
- IoT Sensor Nodes: Micro-resistor networks for wireless temperature/humidity sensors (ultra-fine etchability supports 0.02mm line width).
- Automotive Micro-Electronics: Current-sensing strips for in-car USB charging modules (half-hard temper ensures stamping precision of contact points).
Huona's Micro-Application Support
Huona New Material implements "micro-precision quality control" for 6J13 strips (0.19×25mm): each roll undergoes laser thickness measurement (100 sampling points/m), surface roughness inspection (per 5m segment), and micro-stamping simulation testing (100 samples per batch). Free samples (100mm×25mm, soft/half-hard temper optional) and micro-etching test reports are available upon request.
