Product Description

Product Description:

The term "alumina ball" refers to a type of aluminum ball that is produced using raw materials such as bauxite, rolled powder, alumina, and high temperature calcined α-alumina powder. The manufacturing process involves mixing, grinding, molding, drying, and sintering. These balls are primarily used as grinding media and are commonly used in various industries.

Based on their alumina content, alumina balls can be categorized into three types: aluminum ball, high aluminum ball, and super high aluminum ball. Due to their relatively low cost, aluminum balls and high aluminum balls are widely accepted by ceramics manufacturers, primarily for grinding ceramic materials. The high aluminum balls, on the other hand, are preferred for their excellent properties such as high strength, hardness, wear resistance, small size, high temperature resistance, corrosion resistance, and lack of pollution. These qualities make them suitable for use in different types of ceramics, enamel, glass, and chemical industries, particularly the 92% alumina content ball, which is the most commonly used.


Alumina oxide (AL 2 O 3 ) is a highly desirable ceramic material for use in ball form, thanks to its exceptional resistance to corrosion and ability to withstand high operating temperatures. These qualities make precision alumina oxide balls the ideal choice for applications where durability against abrasion, corrosion, and oxidation is crucial.

Balls made from alumina oxide are often chosen for their outstanding performance in extreme conditions, particularly in high-temperature and high-wear environments. With a proven track record of maintaining dimensional stability at temperatures as high as 3180 ºF, alumina oxide balls are unmatched in their ability to handle intense heat. Our inventory includes a wide range of Alumina Oxide ball sizes, ranging from .031 inches to 1 inch in diameter.



Alumina balls are a commonly used type of grinding and milling media in various industrial applications. They are frequently used in ball mills, grinding jars, and vibratory mills for the purpose of grinding and dispersing materials. This is because they have a high hardness and wear resistance, making them durable and effective for the grinding process.

In addition to their use as grinding media, alumina balls are also widely used as catalyst supports due to their high surface area and thermal stability. They serve as a stable substrate for catalytic materials and can be molded into different shapes and sizes based on specific requirements.

The chemical processing industry makes use of alumina balls as well. They are commonly utilized as fillers, filtering media, and support materials for catalysts to enhance chemical reactions. Thanks to their chemical stability and hydrophobic properties, they are an ideal choice for this purpose.

In the field of micro-electronics, alumina balls play a crucial role as they are used as substrates for various electronic components. This is because they possess exceptional electrical insulation properties, making them suitable for use in such high-precision applications.

Another significant application of alumina balls is in ceramic bearings. Due to their high hardness, wear resistance, and low coefficient of thermal expansion, they are widely used in the manufacturing of ceramic bearings. These properties enable them to withstand high speeds and loads, making them ideal for use in demanding environments.

Alumina balls are also utilized as heat exchangers and transfer media, particularly in high-temperature applications. Their excellent thermal stability makes them perfect for this purpose, as they can withstand extreme temperatures without any significant loss of functionality.

The refractory industry is another major user of alumina balls. They are frequently used in various refractory products, such as furnace linings, crucibles, and casting molds. This is because they have a high melting point and are chemically stable, making them ideal for use in high-temperature and corrosive environments.

Due to their exceptional wear resistance, alumina balls are often utilized as linings for equipment subject to abrasion, such as chutes, pipelines, and tanks. This not only serves to protect the equipment against wear and tear but also extends its lifespan.

Alumina balls are well-known for their excellent electrical insulation properties, making them suitable for use as insulators in high-temperature and high-voltage environments. This makes them an indispensable component in various industries, including electronics, power generation, and aerospace.

In the field of water treatment, alumina balls are used as filtration media due to their hydrophilic properties and ability to remove impurities from water. They are an essential part of many water treatment systems and play a significant role in providing clean and safe drinking water.

In addition to industrial applications, alumina balls also have various biomedical uses. They are commonly used in orthopedic and dental implants, as well as prosthetics, due to their biocompatibility and ability to bond with bone tissues. This makes them a preferred choice for medical applications.

The aerospace industry also makes use of alumina balls, particularly in applications that involve high temperatures, such as rocket nozzles and heat shields. Their thermal stability and resistance to extreme temperatures make them crucial components for these types of applications.

Finally, alumina balls are utilized in the lighting industry for the fabrication of ceramic bulbs and tubes. Due to their excellent optical transmission properties, they are an ideal material for producing high-quality lighting products.
