High Insulator Alumina Ceramic Sleeve / Ring for Vacuum Furnace

Shengda Ceramic provide all kinds of High Insulator Alumina Ceramic Sleeve / Ring for Vacuum Furnace

Product Introduction

Product description

Alumina Ceramic have a high melting point, high hardness,although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. So it is widely used for many mechanical parts which request very high temperature.

Shengda Ceramic provide all kinds of 2, 4, 6 holes alumina ceramic tubes. Also the rings, rods, tubes, plates, inserts, bushing, sleeves, blocks, plunger and so on. Any dimension requirement, please contact us.
