6.0g/cm3 density yttria zirconia machinable ceramic rods
Description:
Zirconia Ceramic offers high strength, wear resistance, and
flexibility far beyond those of most other technical ceramics.
Zirconia is a very strong technical ceramic with excellent
properties in hardness, fracture toughness, and corrosion
resistance; all without the most common property of ceramics – high
brittleness. Its unique resistance to crack propagation and high
thermal expansion make it an excellent material for joining
ceramics with metals like steel.
Our industrial ceramic parts include, tube, rod, plate, disc,
wafer, ring, seal, bearing, valves, pump plunger, beam, roller,
shaft, screw, washer, sleeve, hunger, spacer, holder, carrier,
insulator, fixture, clamp, chuck, nozzle, guide, frame, lining, and
grinding media, milling ball or beads.
