Product Description

Refractory 99% 99.5% Al2O3 Ceramic Alumina Plate / Sheet / Setter

Aluminum oxide ceramics have an exceptional anti-high temperature, high thermal conductivity, good conductivity, mechanical strength, high hardness, and good wear resistance.
It usually takes use of producing a variety of ceramic setters for furnaces.   The max. service temperature can be extended to 1750℃.
Besides, it's easy to get an ideal flatness on the working board via flat grinding, then will greatly benefit the application.

Refractory 99% 99.5% Al2O3 Ceramic Alumina Plate / Sheet / Setter 0


We have in-housing comprehensive manufacturing types of equipment, including forming, sintering, CNC machining, precision grinding, laser cutting and so on, it helps us to control the quality very well, also it greatly benefits to cost control.


Packaging proposal and transportation solutions

1. We will keep the ceramic parts inside the inner package to be fixed without moving,

then it will prevent them from collision each other, to avoid any cause any chippings during transportation.

2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
