Description
High Polish 99%Alumina Ceramic Plate Block
Key Features of alumina ceramic plate block:
1.Its high compressive strength and wear resistance make it an ideal material for manufacturing components such as bearings, seals, and cutting tools.
2.Its high mechanical strength and hardness, making it a durable material for use in harsh operating conditions and environments.
Surface roughness:
The surface processing of alumina ceramic plate sheets can achieve very high precision: the inner hole surface can reach 0.005mm, the outer hole surface can reach 0.001mm, and the mirror polishing can reach Ra0.1.
Finishing ability
1.The maximum height is 600mm
2.The maximum length is 2500 mm
3.The maximum CNC length is 1200 mm
Properties of alumina ceramic plate block:
1.Alumina ceramic plate block also exhibit excellent thermal conductivity and thermal shock resistance, making it well-suited for applications requiring efficient heat dissipation and resistance to thermal stress.
2.Its high thermal stability and resistance to chemical corrosion further expand its potential applications in industries such as aerospace, automotive, and chemical processing.
3.Moreover, alumina ceramic plate block have good electrical insulation properties, making it suitable for use in electrical and electronic applications. Its high dielectric strength and low dielectric loss make it an ideal material for manufacturing components such as insulators, capacitors, and circuit boards for high-frequency and high-power electronic devices.
