OXINIUM™ material is created from a compound of 97.5% zirconium
and 2.5% niobium — two of the most bio compatible metals known —
and with a proprietary process involving extreme heat and oxygenation.
This process yields a revolutionary material with a 5-micron thick
ceramic surface on a core of metal — providing OXINIUM material
with its superior strength and wear characteristics.
