Zirconia ceramic balls have high strength and toughness at room temperature, good wear resistance, high temperature and corrosion resistance, high rigidity, non-magnetic conductivity, and electrical insulation.

Zirconia Ceramic Ball (ZRO2)

The strength and hardness of the zirconia ceramic ball is almost unchanged at 600°C. Its density is 6.00g/cm3, and its thermal expansion rate is close to that of metal.

Silicon Nitride Ceramic Ball (SI3N4)

Silicon nitride ceramic balls are precision ceramics sintered at high temperature in a non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, and can be used for a long time in seawater. Good performance. At 800°C, the strength and hardness are almost unchanged. Its density is 3.20g/cm3, which is almost 1/3 of the weight of bearing steel. The centrifugal force is small during rotation. High-speed operation can be achieved. It also has self-lubricating properties, and it can be used in environments where no lubricating medium is highly polluted. Become the material of ceramic bearings and mixed ceramic ball bearings.

Silicon Carbide Ceramic Ball (SIC)

The performance of ceramic ball products is stable, and the comprehensive performance of silicon nitride is better. Compared with steel, the weight is lighter than steel, the friction coefficient is small, and the movement performance is good. The elastic modulus is 50% larger than that of steel, and the thermal expansion coefficient is less than 25% of steel. It can maintain high strength and hardness before 1000 ℃ at high temperature, and it can resist corrosion. No rust, no magnetism, and can work under oil-free lubrication conditions. Our company is advanced in the production of ceramic balls. Silicon Carbide Ball Material: Pressureless Sintered Silicon Carbide Density: 3.15 g/cm3 Color: Black Grade: G10, G16
