Niobium (Nb) Marker Bands| ALB-Nb-MB

Item No.: ALB-Nb-MB. Niobium (Nb) Marker Bands are made of pure niobium with purity over 99.95%. Size available: OD: 0.2-8.00 mm; WT: 0.015-0.5 mm. Standard: ASTM B 394.

Niobium Marker Bands Description:
ALB Materials Inc is a global supplier of Radiopaque Niobium Marker Bands and Ring Electrodes for the medical industry. Marker band fabrication is the production of metal cut tubing which can be used as radiopaque markers during angioplasty and other minimally-invasive catheter procedures.
Our marker bands can be cut in a variety of lengths and diameters according to customer specifications. Our marker bands, manufactured in platinum+iridium(Pt/Ir), gold, tantalum or niobium are cut into lengths, down to 0.25 mm via an original process which guarantees high precision and a burr-free finish.
