high purity customized sizes precision components in alumina
ceramic part
Precision alumina ceramic parts is an electrically insulating material and the most mature of the
engineering ceramics, offering excellent electrical insulation
properties together with high hardness and good wear resistance,
but relatively low strength and fracture toughness. Alumina
ceramics are generally white but may also be pink or ivory. The
color is derived from either the sintering additives or impurities
in the raw materials.
We can supply the products according to customer's drawings,
samples and performance requirement.We provide OEM, ODM or OBM
service.
We can offer the products base on customer's drawing, sample and
other reference parameter
1) A variety of specifications available.
2) Satisfy various technical request
3) High quality be sure
4) Good insulation performance and high temperature resistance
5) Bending strength and compressive strength resistance
6) Used in all electric products and electric heating products
7) OEM, ODM and OBM are welcomed
The features of products
- High hardness, it is can be 1700 Hv.
- High heat resistance: Alumina ceramic part has excellent thermal
stability, which means that it is widely used in areas where
resistance to high temperatures is essential.
- Good wear resistance: it is the material of chioce for alumina wear
parts.
- High electrical resistivity: used in all electric products, electric heating products and wear
resistant machinery parts.
- High corrosion resistance: It is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
