Mill components (classifiers, air flow mills, bead mills)
General industrial parts (laser processing machine nozzles, shafts, bearings)
High-precision, precision, and heat-resistant metallurgical tools (positioning jigs, assembly jigs)
Wear-resistant parts (guide rollers for wire drawing machines, wire channels, guide rails)
Electrically insulated parts (insulators, gaskets, bushings)
Advantages of Ceramic Sealed Assemblies Ceramic sealed assemblies offer several advantages, including:
Alumina is a white or milky white ceramic that has been used in electronics since the early days for its excellent electrical insulation properties. It is used in large quantities and is the lowest cost material in precision ceramics.
We supply high purity products in 99% and 99.8% . The high purity type of alumina has high mechanical strength and excellent corrosion resistance, enabling the production of large products.
In addition, due to its excellent plasma resistance, it can also be used as a component for CVD equipment or etching equipment.
