Tantalum Marker Band Description
High-quality tantalum marker bands can be bought at SSC. Tantalum marker bands are made from thin-walled seamless tantalum tubes in varying lengths and diameters.
Marker bands are used in the medical industry to make catheter tubes and sensors radiopaque. Typical sizes for marker bands are 0.2-8.0 mm in diameter, 0.015-0.5mm in thickness, and 25 mm in length.
SSC can produce most materials in high purity and ultra-high purity forms.
SSC makes marker bands for medical devices all over the world. Our markers are made of platinum iridium alloy, gold, and tantalum. We can cut down to 0.2 mm lengths for clients using a special method that is very precise and doesn't leave any burrs. Radiopaque marking, ring electrodes, cardiac rhythm management devices, minimally-invasive catheter procedures, stents, and angioplasty are all common uses.
