product name:Alumina ceramic rod
✔ High wear resistance
Aluminum oxide ceramics have wear resistance, but their hardness is the same as that of corundum, reaching a Mohs hardness of 9, and their wear resistance can rival that of superhard alloys.
✔ Good insulation
Aluminum oxide ceramics have excellent insulation properties, with relatively low high-frequency losses but good high-frequency insulation properties;
✔ High heat resistance
Aluminum oxide ceramics have the characteristics of heat resistance, low coefficient of thermal expansion, high mechanical strength, and good thermal conductivity;
✔ Chemical corrosion resistance
Aluminum oxide ceramics have characteristics such as chemical corrosion resistance and molten metal properties;
✔ Excellent characteristics
Aluminum oxide ceramics have the characteristics of non flammability, rust resistance, and non susceptibility to damage, making them excellent properties that are incomparable to other organic and metal materials;
