Alumina rods
Advantages of Alumina rods
1. The alumina rods has strong hardness, second only to diamond in hardness.
2. Alumina rods have the advantages of wear resistance, corrosion resistance, and resistance to impacts,
3. Alumina rods are non-toxic and odorless, suitable for use as machine parts in the medical and food industries.
4. High temperature resistance, long-term use at 1600 ℃, short-term use at 1800 ℃.
5. Alumina rods have electrical insulation properties and can be used as insulating components for electronic experiments.
Applications of Alumina rods
1. Mechanical aspect. Alumina rods widely used for cutting hard materials.
2.Industrial aspect. Alumina rods widely used for industrial valve sealing bearings, sealing rings, ball valves, etc.
3. In terms of electronics and power. Alumina rods widely used for electrical insulation ceramic parts, electronic materials, magnetic materials, etc.
4.In terms of medicine. Alumina rods more commonly used for manufacturing artificial bones, joints, teeth, etc

Clean alumina rods
1.Firstly, place the alumina rod into a mild detergent solution.
2. Gently scrub the alumina rods with a brush.
3. Rinse the rod with clean warm water to ensure the removal of residue.
4. Use a clean and soft cloth to dry the alumina rod and check if it has been cleaned thoroughly.
5.If the stains are severe, please repeat the cleaning process until the alumina rod is completely clean.

FAQ
A1. Ceramics are non-metallic, inorganic materials that are typically composed of a combination of metallic and non-metallic elements. Alumina is a type of ceramic oxide, specifically an oxide of aluminum. It is widely used in various applications due to its excellent mechanical, thermal, and electrical properties.
A2. Because of their excellent chemical stability, alumina industrial ceramic rods are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Alumina industrial ceramic rods are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.
A3. Alumina industrial ceramic rods is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
