Yellow high precision magnesium stabilized zirconia tubes
Description:
Magnesium stabilized zirconia has high oxygen ion conductivity, high strength and toughness, and good thermal shock resistance. It is a very promising high-temperature functional material and structural ceramic material. Magnesium oxide is used as a stabilizer. The cubic phase material is packed into tiny tetragonal deposits and thus has a very high transformation toughness. Magnesium stabilized zirconia has high fracture toughness. It has excellent mechanical properties, including high strength, fracture toughness, wear resistance, low thermal conductivity and good thermal shock resistance.
Principal characteristic :
1. Zirconia ceramics hardness is close to natural diamond, lighter than metal, with never wear, no color and other gem characteristics;
2. High anti-wear, anti-oxidation, never rust, never change color, never cause skin allergy;
3. Degree of insulation, no metal, electroplating pollution, is the ideal environmental protection material in the watch industry
Application :
Because of its resistance to wear and corrosion, it is mainly used in valves, pumps and gaskets, and Manufacture of special ceramic cutting tools, standard measuring tools, mechanical seals, stamping dies and all kinds of wear resistant parts for the mechanical textile industry.
