Huona 0.19*25mm 6J13 Manganin Alloy Strip Ultra-Stable Resistivity

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.

• 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.

• 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%.

• 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.

• 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).
