Laser Cutting 96% Alumina Ceramic Plate Customized Aluminum Ceramic Sheet
Alumina ceramic parts
Alumina ceramic parts are made of aluminum oxide ceramics. Alumina
is a ceramic material with high thermal conductivity, compressive
strength, and thermal shock resistance. It also has a low thermal
expansion, making it a suitable material for furnace use in the
crucible, tube, and thermo couple sheath form. Aluminum oxide is
high hardness and good wear resistance, making it a suitable
material for ball valves, piston pumps, and deep drawing tools. In
addition, alumina ceramic parts can be easily combined with metals
and other ceramic materials using brazing techniques and
metallization.
