Application :  Tantalum ASTM F560 is an approved biomaterial, tantalum radiographic markers consist of tantalum wires and tantalum beads (conform to ASTM F560 ) that are press-fit into small holes in the implant, tantalum wire markers (conforms to ASTM F560) are inserted into the components to give surgeons a visual aid in determining the location of the implant, both inter and post-operatively. e.g. the interbody fusion system is comprised of a variety of components fabricated and manufactured from the material PEEK ASTM F2026-07e1 Standard Specification for Polyetheretherketone (PEEK) Polymers for Surgical Implant Applications or titanium alloy (Ti-6Al-4V) that conforms to ASTM F136 Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401) and ASTM F560 Standard Specification for Unalloyed Tantalum for Surgical Implant Applications.

Tantalum pins are used for medical purposes such as hip-joint replacement, since tantalum is the only metal that is not rejected by bodily fluids. Tantalum pins can display orientation in radiography, since plastic doesn't reflect X-rays, especially have an excellent function in the spinal fusion cages, tantalum pins markers can obtain distinct landmarks, calibrated cages with small tantalum pins markers.

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.

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.
