Application : Tantalum ribbon or tantalum bands can be cut into tantalum marker bands (tantalum cut bands), which are used as medical device components where radiopacity is required, it is the excellent radiopaque marking. Known marker bands are typically constructed of a solid band of radiopaque material, such as platinum, iridium, tungsten, tantalum, gold, etc. and alloys thereof. Typically, the marker band is slipped around and onto a shaft of the catheter and then affixed to the shaft with an adhesive, crimping, or by heating the shaft.

ASTM F 560 medecal grade Tantalum, element #73, is a shiny, flexible, and highly radio-opaque metal. Though more brittle than stainless steel, tantalum exhibits high ductility and resistance to corrosion. tantalum marker bands, radiopaque markers (tantalum bands), tantalum thin film, tantalum marker, tantalum markers, tantalum per ISO 13782 -Implants for surgery -- Metallic materials -- Unalloyed tantalum for surgical implant applications, tantalum medical devices in conformity with ISO 13485 quality management system, etc.,

ASTM F 560 medecal grade Tantalum is ideal for viewing and supporting, but more biocompatible options exist.

ASTM F 560 medecal grade Tantalum is a highly radiopaque material, which is easily seen on fluoroscopy.

ASTM F 560 medecal grade tantalum exhibits excellent radiopacity and it is also Magnetic Resonance Imaging (MRI)-compatible.

The bioinertness of tantalum was reconfirmed as was its suitability for use as skeletal and soft tissue radiographic markers.
