Special Shaped Wear-Resistant Ceramic Pieces Porcelain Eyes
Product Overview
Special-shaped ceramics have excellent strength, hardness,
insulation, thermal conductivity, high temperature resistance,
oxidation resistance, corrosion resistance, wear resistance, high
temperature strength and other characteristics. Therefore, it shows
high stability under very harsh environment or engineering
application conditions. The mechanical properties have aroused
widespread concern in the material industry, and its scope of use
is also expanding. Global and domestic industries are becoming more
and more strict with high precision, high wear resistance, high
reliability mechanical parts or electronic parts. Therefore, the
demand for ceramic products has received great attention, and its
market growth rate is also considerable.
