6.0g/Cm3 Yttria Zirconia Ceramic Rods Machinable 2000mm
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.
