Product Description
6J13 Manganin Alloy Strip (0.19mm Thickness × 25mm Width)
Product Overview
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.
Unlike generic manganin strips, its fixed thin gauge and narrow
width are tailored for miniaturized, high-batch precision
components—integrating balanced resistance stability, excellent micro-stamping performance, and cost-effective batch production advantages. It has become the core material for micro-current shunts,
miniaturized resistor networks, and portable sensor elements in
consumer electronics, automotive micro-electronics, and IoT
devices.
Standard Designations & Specification Value

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)

specialized thin-gauge alloy rolling lines (minimum rolling
thickness 0.01mm)
Key Fresh 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. 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.
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, 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.
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. 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).

Huona's Micro-Application Support (Value-Added)
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
