Slotted Alumina Ceramic Rods
My factory looking for distributors.
Our alumina ceramic tubes are exported to more than 30 countries. The quality of our products is deeply liked by customers. Crucible products are also purchased by many university laboratories and mining laboratories. Parts products are also ordered by many large machine companies.
All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680
Features of alumina wear-resistant porcelain rods:
1. Large hardness
Measured by professional research institutes, its Loss hardness is HRA80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel.
2. Good wear resistance
After research and determination, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. According to our customer follow-up survey over the past ten years, under the same working conditions, the service life of the equipment can be extended by at least ten times.
3. Lightweight
Its density is 3.5g/cm3, which is only half that of steel, which can greatly reduce the equipment load.
4. Wide range of application
Alumina ceramics is a very wear-resistant precision ceramic material, which is widely used in electronics, steel, smelting, machinery, coal, mining, chemical, medical, military, aviation, photovoltaic semiconductors, etc. On all the machinery and equipment of the enterprise with great wear and tear, different types of products can be selected according to different needs.

8.What is the difference between ceramic and alumina?
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.
9. What is alumina ceramic used for?
Everything You Need to Know about Alumina Ceramics
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.
10. Is alumina ceramic hard?
Alumina is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products.
