Honeycomb Materials:

NIMRA has a combination of high strength (from zirconia) and high hardness (from alumina phase).

It is an aluminum oxide strengthened with a content of 15% (Y2O3 - stabilized) zirconium oxide. Together aluminium oxide and zirconium oxide form an composite phase.

The larger zirconia atoms reinforce the lattice structure and create greater compression strength than standard alumina. The zirconia reinforces the aluminum oxide web and arrest the cracks from further propagating. This gives NIMRA'S TOUGHENED ALUMINA increased impact resistance. 

It has excellent wear resistance, both in sliding and abrasive conditions. NIMRA'S TOUGHENED ALUMINA provides a cost effective material solution to the most demanding applications which require wear resistance, errosion resistance, high temperature stability and superior mechanical strength. 

NIMRA honeycombs can be manufactured to precision tolerances and finish in a wide range of shapes and sizes with tailored mechanical properties.
