Oxidized Zirconium

Fatigue Strength

Fatigue Strength 6

ASTM standards require implants to withstand loads that would normally be characterized as extreme. This test simulated worst-case physiological conditions. The OXINIUM components were found to support a minimum fatigue load of 1,000 lbs. for 10 million cycles, which is equivalent to a cobalt chrome femoral component of the same design.

  • This test shows the metal-like fatigue strength and toughness of the OXINIUM component, unlike ceramic components that could shatter under these conditions.
