Product Description

Product Overview

CuNi6 micro wire is a copper-nickel alloy precision wire containing 5.5%-6.5% nickel, offering balanced conductivity, corrosion resistance and mechanical properties, widely used in electronics, electrical engineering and precision instruments.

Key Feature

Stable Resistivity
Low resistivity (0.019 Ω·mm²/m) and small temperature coefficient (0.0006/ºC), ideal for precision resistance components

Corrosion Resistance
Resistant to seawater, humid atmosphere and weak acid/alkali, suitable for marine engineering and chemical equipment

Excellent Workability
Easy to draw, bend and weld (supports brazing/fusion welding)

Surface Options

Available in bright, pickled or tin-plated finishes to meet various conductivity and protection requirements
