High quality alumina part/ zirconia ceramic piston
Zirconia ceramic due to its high toughness, high bending strength and thermal expansion coefficient close to the iron and steel, etc., it is widely used in elect-ronics, machinery, aerospace, petrochemical and other fields. As a structural ceram-ic components, the main properties of zirconia ceramic has the following advantages:
High density
Good corrosion resistance
High strength and fracture toughness
High hardness and wear resistance
High temperature resistance and Low thermal conductivity
Performance
Physical properties: high insulation resistance, breakdown, high temperature resistance, abrasion resistance, high strength (three meters altitude fall not broken)
Fire rating: USA military standard MIL-F-51058 (the highest level)
Typical application: strong current, voltage, strong high temperature parts, IC MOS, IGBT power tube heat pipe insulation
Certification: natural organic matter, the European Union, exempt products without certification materials
Thermal conductivity: high temperature: 1600 degrees below the ideal heat insulating material of high voltage and high frequency equipment.
