Product Description

heat sink aluminum oxide ceramic substrate sheet

Reputation depends on quality, quality comes from Hard!

Alumina Ceramics:

Alumina: It is one of the most widely used raw materials in boron carbide nozzle products and has a series of excellent properties. In addition, it is also an important raw material for high temperature refractories, abrasives, abrasives, laser materials and alumina gemstones. Zirconia: it is a high temperature structure boron nozzle

Alumina is one of the hard man-made materials, which has the characteristics of light weight, semiconductor physical properties, absorption of neutrons, high grinding efficiency, no reaction with strong acid and strong alkali, Mohs hardness of 9,36 and microhardness of 5400~ 6300 kg per square meter, density is 2.52 kg per square meter, melting point is 2450 degrees Celsius, boron carbide is hexagonal dark black, due to the above characteristics and properties, boron carbide is widely used in machinery, metallurgy, chemical, aerospace military and other fields. Abrasives can be used to process gemstones, ceramics, knives, bearings, and refractory materials for use in various fields of metallurgy. Densified boron carbide can be used as nozzles, mechanical seals, and ballistic resistant materials due to the greater heat of boron carbide. The neutron capture cross section, which absorbs a large amount of neutrons, can be used in high-tech fields such as nuclear reactors. As a new type of material, engineering ceramics is widely used in chemical, mechanical, electronic, information, aerospace due to its high melting point, high hardness, high modulus of elasticity, strong wear resistance and good self-lubricating properties. , automotive and other industries.
Features of boron carbide products: It has the same properties as boron carbide, extremely hard and wear-resistant, does not react with acid and alkali, high temperature resistance, reactor, neutron absorption rod, bulletproof tools, etc. Boron carbide sealing ring and sand blasting nozzle can replace known hard alloy and sealing ring made of silicon carbide, silicon nitride, alumina, zirconia, etc.
alumina ceramics


High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.

  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 .
