TECHNICAL PRODUCT INFORMATION

Plated Tungsten Wire

Ultra-Fine Tungsten Wire with Precision Surface Engineering

Precision plated tungsten wire combines the exceptional strength, stiffness, and high-temperature performance of tungsten with application-specific surface properties achieved through advanced reel-to-reel plating.

At Luma Wire Tech, we manufacture ultra-fine tungsten wire from 5 to 200 microns and enhance its performance using precision coatings tailored to demanding applications. Depending on the selected plating material, tungsten wire can be optimized for improved electrical conductivity, corrosion resistance, wear resistance, solderability, or long-term contact reliability.

Manufactured in Sweden under ISO-certified processes, our plated tungsten wires support high-performance applications across medical technology, electronics, aerospace, scientific research, defense, and technical textiles.
