Reliable Bar Shaped Alumina Ceramic Parts High Temperature Machinable
The alumina ceramic 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 of alumina ceramic bar:
1.High temperature, Max working temperature: 1700C.
2.Excellent wear and abrasion resistance.
3.Good chemical corrosion resistance under high temperature.
4.High dielectric properties.
5. High oxidation resistance.
