Alumina ceramic (Al₂O₃) precision structural parts, including ceramic parts in various shapes, are mainly used for electrical insulation, mechanical support or wear-resistant parts.
Product composition and characteristics:
Large ring piece:
Thick-walled circular ring with gold/yellow-brown coating or insert (possibly metallized layer or sealing ring) on the inner ring.
Used for high-voltage insulating flanges, bearing seats or sealing structures.
Holed round gasket:
Multiple disc-shaped parts with a through hole in the center and 2 small mounting holes on the outer edge.
Typically used for flange gaskets, motor insulation end plates, and sensor mounting seats.
Square block pieces:
L-shaped or stepped blocks with through-holes and counter-bores.
For use on mechanical mounting brackets, insulating terminal bases or equipment positioning blocks.
Material and performance:
Material: high-purity alumina ceramic (Al₂O₃), white, dense and smooth.
Features:
High dielectric strength (high voltage resistance)
High hardness and wear resistance
High temperature resistance (up to 1600℃)
Resistant to corrosion and chemical attack
Dimensional stability, precision machining
Typical application scenarios:
Power equipment: high-voltage insulators, transformer bushings, switch cabinet insulation parts
Motors and generators: rotor/stator insulated end plates, bearing insulating sleeves
Semiconductor and photovoltaic equipment: wafer transfer fixtures, vacuum chamber insulators
Chemical and medical equipment: corrosion-resistant sealing rings, high-temperature reactor linings.
