Comparison of Wear Resistance
What is Honeycomb structure Ceramic?
Honeycomb structure Ceramic is a composite
material consisting of a core (gray portion) and
shell (white portion)
l
Improved wear and fracture
resistance due to the mixture of
the hard and acicular particles
Superior balance in heat
resistant alloys machining
achieves optimum balance
between wear and fracture
resistance.
