About Alumina TubesAlumina Ceramic tubes have exceptional hardness and strength, resistance to chemical attack and wear, low dielectric loss and excellent electrical insulation properties. Additionally, Alumina can be metallized for brazing to other metals, highly polished, and comes in a variety of purities depending on it use. Due to these outstanding properties ceramic Alumina tubes are used in a wide range of industrial and advanced applications.For more information on Alumina please refer to our General Alumina Page. Additionally, we supply extruded ceramic Alumina tubes and pipes offered in both stock sizes and custom sizes, designed and machined to precise customer specifications. If you would like to buy Alumina Tubes or have any questions, please contact us and one of our experts will be happy to assist you. Available Grades

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.

Process of production:
Q1: How to send an inquiry
You can send your drawing with technology requiremens,and infrom your purchase quantity .If you can,pls inform what is your part used in .We will confirm what is the most suitable materials and quote our best price to you in 24 hour
Q2:Can you provide the free samples ?
Yes,we can provide the sample free of charge if we have the stock product as customer's required,but the courier fee be collected.
Q3:How long will it take for you to send me a quote?
This depends on the complexity of your requirements. For simple items such as plates and rods, we can generally supply a quotation within 24 hours.
Q4:What's the delivery time?
For the standard products, like ceramic substrate and insulating rods, delivery time is normally 7 working days. For hot pressed boron nitride and machinable glass ceramic, it's about 10 working days. For customized products made of alumina, zirconia, boron carbide and silicon nitride, total producing time is about 30-45 working days.
