Product description
Product Description:
Wear Resistance Black Ceramic Tube
Silicon nitride ceramic is a kind of inorganic material that does not shrink during sintering. Silicon nitride is very strong, especially hot pressed silicon nitride, one of the hardest materials in the world. It has the properties of high strength, low density, high temperature resistance and so on. With the characteristics of light weight and large rigidity, Si3N4 can be used to make ball bearings. It has higher accuracy than metal bearings, and produces less heat, and it can operate in higher temperature and corrosive medium. The steam nozzle made of Si3N4 ceramics has the characteristics of wear resistance and heat resistance. It has no obvious damage for 650 degree boiler after a few months, while the other heat and corrosion resistant alloy steel nozzles can only be used for 1-2 months under the same conditions.
Production range:
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
