High Purity Industrial Refractory Alumina Ceramic Roller Resistant To High Temperature

 

 

1.Alumina ceramic roller  

 

The alumina tube/rod/bar is an ideal wear-resistance material for delivering the sand, mine, ash dregs and molten aluminium, has excellent conductivity, high machinery strength and high temperature resistance, can resist to the acid, high temperature, corrosion and static electricity. Al2O3 is the most important technical ceramic material. It is characterized by high hardness, high compressive strength and corrosion resistance even at high temperatures. Through the content of Al2O3 in the material,these properties can be tailored to the application of customer.

 

 

 

Features:

1) A variety of specifications available.

2) Satisfy various technical request

3) Lower medium spoilage

4) Good insulation performance and high temperature resistance

5) Stiffness texture

6) Used in all electric products and electric heating products

7) OEM, ODM and OBM are welcomed

 

We can supply the products according to customer's drawings, samples and performance requirement.

 

Alumina ceramic is kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, 200T isostatic pressing and extrusion productive technology etc.
