Product Description
al2o3 alumina ceramic Washers spacers sleeves shafts
Reputation depends on quality, quality comes from Hard!
Alumina Ceramic:
The main crystalline phase is α-A12O3. The density is 3.98 g/cm3 or more. The linear transmittance is 90% to 95% or more. The dielectric constant is greater than 9.8. The dielectric loss tangent is less than 2.5×10-4 (1GC), and the flexural strength is greater than 350-380 MPa. The breakdown strength is 6.0 to 6.4 kV/mm. Thermal expansion coefficient (6.5 ~ 8.5) × 10-6 / °C. Good alkali metal vapor corrosion resistance at high temperatures.
The raw material is Al2O3 with a purity of 99.99% or more, and a small amount of additives such as pure magnesium oxide, antimony trioxide or antimony trioxide are added, and continuous isostatic pressing, atmosphere sintering or hot press sintering is performed, and the grain size is strictly controlled. Highly dense transparent ceramic.Luminous tube for the manufacture of high pressure sodium lamps (working life can exceed 20,000 h). It can also be used as a microwave integrated circuit substrate, bearing material, wear-resistant surface material and infrared optical component material.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.

SHENZHEN HARD PRECISION CERAMIC CO.,LTD
Shenzhen Hard precision ceramics Co., LTD. has been committed to design, development and manufacture of industrial ceramic products since 2007. Compared with metal, advanced ceramic has the following excellent performance: high hardness, high strength, high temperature (fire), and can wear resistance, corrosion resistance, acid and alkali resistance, oxidation resistance, insulation, non-magnetic and good chemical stability . So it is often used in the environment where the metal material cannot endure. With its promising application , advanced ceramics are widely used in aerospace, aviation, military industry, nuclear power, machinery, textile, chemical, electronics, food, medical and other industries. Our advanced ceramic products made by zirconia (ZrO2), alumina (Al2O3), silicon nitride (Si3N4), etc. Our products can divide into two parts: one part is ceramic ball, rods, tubes, ceramic materials such as plate, block, strip and so on, and the other part is the precision ceramic parts which are for industrial use and civilian products. Our company has advanced one-stop equipment and technology of ceramic forming, sintering and processing. Hope we can establish excellent cooperation with customers from at home and abroad for a wide range .
