Alumina Parts & Components
Alumina ceramics (Al₂O₃), also known as corundum, are among the most widely used ceramic materials in the industrial sector. They are primarily composed of high-purity aluminum oxide and are renowned for their exceptional hardness, high-temperature resistance, excellent electrical insulation, wear resistance, and superior corrosion resistance. Alumina ceramics are processed into various components used in high-temperature electrical equipment or wear-resistant parts. These ceramics are widely applied in industries such as semiconductors, electronics, automotive, and chemicals, especially in environments that demand high temperature and wear resistance. Through precision machining, alumina ceramics can be shaped into complex, high-performance components such as electrical insulators, seals, and wear-resistant liners. Their high hardness allows them to maintain stable performance under harsh working conditions, significantly extending the service life of equipment.
Alumina ceramic parts are ideal for use in military, aerospace, semiconductor manufacturing, energy, chemical industries, and various equipment components that operate under harsh conditions, particularly as replacements for metal materials where high toughness is not a critical requirement.· Electrical insulation parts
