Medical Wire

Tantalum & Tungsten-Rhenium Alloys: W, W3Re, W5Re, W25Re

Concept Alloys produces wire for medical applications, specializing in the use of our expertise with refractory metals, particularly different grades of tungsten and tungsten-rhenium formulations.

Concept Alloys’ medical wire is suitable for a wide range of applications, primarily for various surgeries. The size range, ductility and specific size/shape quality properties of Concept Alloys’ tungsten-rhenium wire enables our medical wire to be customized for specific cardiovascular and diagnostic applications.

Our wire is often the precise part of a medical device used to perform either Laparascopic (Minimally-Invasive) or Endoscopic surgical procedures.
