Alumina Ceramic Nut Parts
My factory looking for distributors.
Advantages of alumina ceramic nut parts
1.This is the alumina ceramic nut parts, it is soild screw bar, the screw size is M2. We also accept the custom size and shape about this parts.
2.Compared with common metal parts, alumina ceramic nut parts have higher hardness and strength, better wear resistance, better stability, excellent biocompatibility, etc.
3.Alumina ceramic nut parts have the characteristics of high temperature resistance, corrosion resistance, rapid cooling and rapid heat, high mechanical strength and superior electrical performance.
4.Alumina ceramic nut parts are widely used in industrial equipment manufacturing and other fields.
Applications of alumina ceramic nut parts
1.Alumina ceramic nut parts can be used as protective and insulating tubes for temperature measuring instruments, thermocouples, and thermometers.
2.Alumina ceramic nut parts can be used for carbon and sulfur determination tubes in steel chemical analysis.
3.Alumina ceramic nut parts is used as the basic ceramic component for insulation instruments and components that are resistant to high temperature, acid and alkali corrosion.

FAQ
Q1. What is the difference between ceramic and alumina?
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.
Q2. What is alumina ceramic used for?
A2. Because of their excellent chemical stability, alumina ceramics are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Aluminum oxide ceramics are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.
Q3. Is alumina ceramic hard?
A3. Alumina is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
