MWS Medical Plated Wire

Conductor Material

The variety in applications and targeted functionality of medical wire places significant emphasis on the choice of alloy (conductor material) used. Characteristics to consider are electrical conductivity and resistivity, strength, fatigue life, ductility, thermoelectric properties, biocompatibility, high tensile strength, expansion coefficient, magnetic attraction, melting point and resistance to oxidation or corrosive environments. This elevates the importance of material science and availability of alloy choices provided by MWS to our medical customers.
