Alumina Ceramic Custom Finishing
Aluminium Oxide structure ceramics parts
Alumina ceramics are also known as precision ceramics, special ceramics, or high-tech ceramics. It is a ceramic with highly selected raw materials, produced according to a special manufacturing process, which can precisely control the chemical composition and has excellent properties. Currently, alumina ceramics are mainly used in high-tech and cutting-edge industries, such as microelectronics, nuclear reactors, aerospace, magnetic fluid power generation, artificial bone and artificial joints. Alumina ceramics in the manufacturing process.
Customised Production:Customised production involves tailoring the manufacturing process to meet specific customer requirements. In the context of aluminium oxide ceramic blind tubes, this may include customising the dimensions, shapes, surface finishes, and other specifications to suit the intended application.
Main characteristics: high melting point, high hardness, can be made into transparent ceramics, non-toxic, insoluble in water, high strength.
Main applications: corundum ball mill, lamps for high pressure sodium lamps, crucibles, tap valve cores.
SHENZHEN HAORUI can offer not only qualified products, we can also supplying quality service including design, development, export and after sales. With our professional skills, advanced technology and quality material, we can design and develop new products or new applications according to the clients' expectation. We have custom-made new products and promoted the specifications for more than 1000 clients, and we have gotten good reputation from our clients.
