Material Introdution


Alumina ceramic (Aluminum Oxide or Al2O3) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. Additionally, it is extremely resistant to wear and corrosion. Alumina components are used in a wide range of applications such as electronics, pump components and automotive sensors. UNIPRETEC offers a variety of alumina compositions, including 92% Alumina, 95% Alumina, 96% Alumina, 99% Alumina, 99.5% Alumina and 99.8% Alumina. Alumina components can be formed by a variety of manufacturing techniques such as uniaxial pressing, isostatic pressing, injection molding and extrusion. Finishing can be accomplished by precision grinding and lapping, laser machining and a variety of other processes.

  • Ceramic Welding Roll

    Ceramic Si3N4 Welding Rolls for Steel Tube Industry

    silicon nitride ceramics is an inorganic non-metallic material. It is a super-hard material, which has lubricity and is wear-resistant; except for hydrofluoric acid, it does not react with other inorganic acids. It is highly corrosive and resistant to oxidation at high temperatures. Moreover, it can resist high thermal shocks. It will not crack when heated to over 1,000°C in the air, cooled rapidly and then heated rapidly. Because of the excellent characteristics of Si3N4 ceramics, it’s often used to manufacture bearings, turbine blades, mechanical seal rings, permanent molds and other mechanical components. In the field of welding of copper stainless, and aluminum tubes, silicon nitride ceramic rolls have natural advantages.

  • boron nitride setters

    Ceramic Boron Nitride Setters for Nitride Ceramics Sintering

    Boron Nitride can be compared to graphite thanks to lubrication capacities, good thermal conduction and easy machinability, although it's white and has good electrical insulation. Plus, it isn't wetted by most molten metals and can therefore be used as a container for most molten metals.
