• 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)

• 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. It perfectly fits the thickness requirement of smartphone fast-charging shunts and wearable sensor resistors.

• 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, meeting the production of micro-resistor grids for IoT sensor nodes (which require line width accuracy ±0.003mm).

• 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%—solving the "batch inconsistency" pain point of thin-gauge strips in automated production.

• 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. For customers producing small-batch micro-components, it avoids inventory waste of wide strips.

• Dual-Temper Optional: Offers both soft (annealed, elongation ≥25%) and half-hard (elongation 15-20%) tempers for different processes—soft for complex bending (e.g., wearable device sensor leads) and half-hard for high-precision stamping (e.g., micro-shunt contacts).

• 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—reducing production costs for charger manufacturers).

• Wearable Health Sensors: Resistance elements for smart watch heart rate sensors (soft temper enables 0.38mm radius bending, narrow 25mm width reduces material waste for small sensor production).

• IoT Sensor Nodes: Micro-resistor networks for wireless temperature/humidity sensors (ultra-fine etchability supports 0.02mm line width, ensuring sensor signal accuracy ±0.1℃/±1%RH).

• Automotive Micro-Electronics: Current-sensing strips for in-car USB charging modules (half-hard temper ensures stamping precision of contact points, stable TCR adapts to in-car temperature fluctuations -10℃ to 60℃).
