Features of Alumina Ceramics：
1.They have high mechanical strength. The flexural strength of sintered alumina ceramic products can reach 250MPa, and that of hot-pressed products can reach 500MPa. The strength can be maintained up to 900℃ at high temperatures.
2. Alumina ceramics have a high resistivity and excellent electrical insulation performance. The resistivity at room temperature is 1015Ω·cm, and the insulation strength is 15kV/mm.
3.High hardness, with a Mohs hardness of 9.
Advantages of Alumina Ceramics:
1.Mechanical parts made of alumina precision ceramics not only have the characteristics of strong wear resistance, but also can withstand harsh environmental conditions such as high temperature, high pressure and corrosion. This makes it widely used in the manufacture of heavy machinery and equipment, such as shipbuilding, aerospace, automobile manufacturing, and other industries.
2.Alumina precision ceramics also play an important role in the field of electronic devices. Electronic devices often need to have good insulating properties and electrical conductivity, and alumina precision ceramics meet these requirements. Not only is it able to effectively resist the conduction of electric current and heat, but it is also able to withstand high voltage and high frequency electromagnetic interference.
3.As a material with excellent functions, alumina fine ceramics have important application value in the fields of mechanical processing, electronic devices and medical devices. Its unique properties, such as high hardness, abrasion resistance, and high temperature resistance, make it one of the indispensable materials in many industries.
