High Purity Alumina Ceramic Ring For Semi-conductor Usage
Alumina Ceramic Ring is of high wear resistance, acid and alkli resistance, effectively prolong the service life of equipment and considered to be the best choice of anti-wearing and anti-corrosion material; Wear resistance of ceramic is 266 times than that of special manganese, 171.5 times to high chrome cast iron; Hardness is much higher than that of wear-resistant steel and stainless steel. Application: Oil, mining, steel and power industry.
Alumina ceramic ring is a kind of super high temperature resistant material, of which 97 alumina can work in the environment of 1500 ℃, and 99 alumina can be more resistant to 1700℃. At present, alumina ceramics are widely used in high-temperature equipment parts, such as high temperature stirring rods, high-temperature insulating tubes, kiln furnaces. 99% aluminum oxide tubes, also known as 99% corundum pipes. Alumina ceramics are one of the best refractory materials, and others like zirconia ceramics, aluminum nitride ceramics, silicon carbide ceramics and so on.
Mingrui offers you a wide range of production facilities like extrusion, injection moulding, pressing and casting. Depending on product geometry and quantities, we will choose the suitable technique for your products.For the final finishing of the parts we use CNC machining centres, equipped with diamond tools in order to meet high accuracies.
Our aim is to offer the ideal solution for any application. Our engineers therefore offer custom solutions that range beyond our existing product portfolio. With our well-equipped industrial development facilities, we produce innovations that can be rapidly commercially exploited
