    Alumina Ceramic Parts

    Alumina parts are made of aluminum oxide, which is one of the most important and versatile materials in the field of oxide ceramics. This material therefore used in a wide range of applications. The alumina ceramic from UNIPRETEC has a Al2O3 purity up to 99.8%. Due to the fine structure of the material and its high surface quality, an unsurpassable combination of properties can be achieved.

  • 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.
