Introduction
Silicon Nitride Ceramic Grinding Beads, with a bright black color, weigh one-third of steel, have a hardness second only to diamond, and have many excellent properties compared to other materials, including low density, high strength, high temperature resistance, corrosion resistance, long service life, self-lubrication, high hardness and toughness, and non-magnetic insulation. They are the best structural ceramic in terms of comprehensive performance and are known as "all-purpose ceramic."
Because of their excellent comprehensive performance, Silicon Nitride Ceramic Grinding Beads are widely used in fields such as aerospace, spaceflight, navigation, nuclear industry, petrochemical industry, medical equipment, light industry, metallurgy, power generation, food processing, transportation, and high-speed machining.
Our company's drop-casting process-made 0.1mm Silicon Nitride Ceramic Grinding Beads fill the technical gap in the entire industry and add more possibilities to the high-end material grinding.
Characteristics
1.High hardness Silicon Nitride grinding media balls have good wear resistance and stable structure, making them suitable for precision processing and application in many special fields and industries.
2. Non-magnetic insulation Indoor resistivity is as high as 1013 ohms per centimeter, and it can conduct electricity when the temperature rises to 600°C.
3. Are corrosion-resistant and can withstand acid and alkali, making them suitable for long-term use in seawater.
