Alumina ceramic balls are ceramic spheres made from alumina as the main raw material, which are fired at high temperatures and then molded using molds. After some grinding and polishing, they become high-precision ceramic balls. The alumina content is 95%, which is relatively high, and therefore their performance is also very excellent.
1.High hardness and high wear resistance:
Its hardness is second only to that of diamond and silicon carbide, with a Mohs hardness of up to 9. This enables it to have an extremely long service life in grinding and wear environments, being several times or even dozens of times more wear-resistant than steel balls.
2.Corrosion Resistance:
It has extremely strong resistance to most acids, bases and organic solvents and will not rust. It is suitable for corrosive environments such as those in the chemical and pharmaceutical industries.
3.Heat resistance:
It can maintain its shape and properties even under high temperatures (usually above 1600℃), without melting or deforming. This makes it highly suitable for use as load-bearing supports in high-temperature kilns (such as kiln bodies, roller rods), etc.
4.High mechanical strength:
It has extremely high compressive strength and can withstand tremendous pressure without breaking.
5.Electrical insulation:
It is an excellent electrical insulating material and can be used in the fields of electronics and electrical engineering.
6.Good chemical stability:
It does not contaminate the processed materials, making it particularly important in the food, pharmaceutical and cosmetic industries.
