Oxinium is a shiny black metal alloy with a ceramic surface and is made up of 97.5% zirconium and 2.5% niobium. The base material, zirconium, is one of the prime biocompatible metals, with a very high fracture and fatigue strength, similar to a cobalt-chromium alloy, and with a level of elasticity almost equal to that of titanium alloys. Oxinium\u2019s ceramic surface is not a coating, but instead actual zirconium that has been ceramicized using a process of oxidation and heat. This means that prosthetics made of this material have the unique hardness, abrasive resistance, and sliding properties of ceramics - yet the fracture strength and elasticity of metal.<\/p>\n\n\n\n

Zirconium (along with titanium, tantalum, platinum, and niobium) is one of the five most biocompatible metals on earth, meaning that the body tolerates it very well.<\/p>\n\n\n\n
