Alumina Ceramic Substrate
My factory looking for distributors.
Al2O3 substrate is the most popular ceramic substrate, with excellent heat resistance,
high mechnical strength , abrasion resistance and small dielectric loss .
The surface of alumina substrate is quite smooth and low porosity , 99.6% alumina substrate
is suitable for thin film device , 99.3% alumina substrate is suitable for thick film device application.
USES of alumina ceramic plate
Alumina ceramic substrate is often used in chemical and physical grinding environment, especially high purity alumina is a very good material for producing wear-resistant components.
These components include shafts, pistons, bearings and mating end face seals. They are mainly used in chemical and physical conditions and are good corrosive media. These components can be used to manufacture circulating pumps, reciprocating pumps and resonator-supported products.
We use ceramic injection molding and grinding to produce a variety of complex components with strict surface finish and flatness requirements. At the same time, our manufacturing process can also meet the requirements of small and batch production.
We only make high purity alumina ceramics
1. material: 99.3% Alumina ceramic etc.
2. method of moulding: thermal casting/drying press/extrusion
3.colour: white
4.sintering temperature: 1800c
5.surface finish:Ra0.4 &SIM RA 0.8&mum etc, upon your requirement.
6.package: packing with carton and ship with wooden box.
7.we can produce them by your molds or te drawings you require.
