Sandvik Bioline cored wire (SBCW) is a composite wire consisting of a Sandvik Bioline F562 CoCrMo alloy shell and a secondary alloy as the core material. The core material is typically pure silver (Ag) to promote increased conductivity relative to solid Sandvik Bioline F562. However, other core materials such as platinum (Pt), gold (Au) and tantalum (Ta) can be selected in order to increase the radiopacity or provide other unique combinations of properties to the composite wire. The standard core dimension is 25% by area, however other core sizes can be considered.

The outer component is characterized by:

• Excellent corrosion resistance

• Excellent fatigue properties

• High strength combined with good ductility

The inner silver core provides:

• High electrical efficiency

• Electrical conductivity

• Low electrical resistance.

Sandvik Bioline cored wire can be used for cochlear implants, pacemaker, defibrillator leads and varicose vein surgery devices.

Applications
Sandvik Bioline Cored Wire (SBCW) is a preferred grade of composite wire for medical applications because the highly favorable combination of excellent corrosion resistance, high strength and moderate conductivity.

Typical applications are lead wires for medical devices such as pacemakers, defibrillators and cochlear implants.
