Microelectronics & Sensors
Microelectronics and sensor manufacturers need ultra-fine nickel wire with micrometer-level tolerances for RTD elements, MEMS actuators and precision resistors. Hansemut sources NP1/NP2 wire from 0.025 mm — with inline diameter and resistance verification.
Sourcing ultra-fine wire for sensor applications is a precision challenge.
Diameter tolerances at micrometer level
A sensor wire at 0.025 mm needs +/-0.001 mm tolerance. Most wire suppliers cannot hold this across full spool lengths without inline monitoring.
Resistance uniformity along length
RTD and strain gauge applications require constant resistance per meter. Variations along the wire cause measurement drift and calibration failures.
Small quantities, high specifications
Sensor production runs are often small but specifications are extreme. Finding a supplier willing to produce 1 km of ultra-fine wire to tight specs is difficult.
Precision nickel wire with verified tolerances along every meter.
Inline diameter measurement
Wire diameter is measured continuously during drawing using laser micrometers. Tolerance of +/-0.001 mm is verified across the full spool length.
Resistance protocol per spool
Specific resistance is measured at multiple points along the wire and documented. You receive a resistance certificate alongside the standard CoA.
Flexible quantities from 1 km
Minimum order from 1 km total length. Qualification samples from 50 m available — so you can validate before committing.
Validate ultra-fine wire in your sensor prototypes
Request sample spools with inline-verified diameter and resistance protocols — test wire performance in your RTD elements or MEMS assemblies.
How nickel wire enables precision sensing
MEMS Sensors and Micro-Actuators
Ultra-fine NP2 nickel wire at 0.025 mm diameter is integrated into MEMS micro-actuators and membrane-based pressure sensors. Consistent resistivity along the wire length ensures stable calibration in miniaturized measurement systems operating at microvolt signal levels.
Bond Wires for Chip Interconnects
NP1 high-purity nickel wire serves as bond wire material for specialized interconnects in power electronics and hybrid modules. Oxide-free bright-drawn surface ensures reliable wedge bonding with consistent pull strength across high-volume production.

Microelectronics & Sensors
Microelectronics and sensor manufacturers need ultra-fine nickel wire with micrometer-level tolerances for RTD elements, MEMS actuators and precision resistors. Hansemut sources NP1/NP2 wire from 0.025 mm — with inline diameter and resistance verification.
Standard: 0.025 mm (25 um). For even finer diameters, we coordinate with the manufacturer to evaluate feasibility for your application.
NP1 (99.98% Ni) has a more linear temperature coefficient — critical for precision RTD elements. NP2 (99.94%) is suitable for general sensor and actuator wiring.
Yes. Precision spools with defined winding tension and specified spool dimensions are available. Custom lengths per spool on request.
