Silicon nitride ceramic wheel
SHENZHEN HAORUI INDUSTRIAL Silicon Nitride is a durable and resistant ceramic substance that is significantly lighter than steel, weighing only 60% of its weight. This specific type of Silicon Nitride, known as Sintered Silicon Nitride (Si₃N₄), is specifically engineered to possess a range of exceptional qualities, including resistance to thermal and impact shocks, electrical insulation, and protection against wear. The versatility of SHENZHEN HAORUI Silicon Nitride allows for various design options, making it an excellent substitute for stainless steel, superalloys, tungsten carbides, and older ceramics like Al₂0₃ and ZrO₂. These advantageous characteristics make SHENZHEN HAORUI Silicon Nitride the ideal solution for measuring wheels.
Application industry:
Machinery, electronic, semiconductor, chemical, petroleum, smelt.
Specific application:
Welding shaft, electronic substrate, plunger, nozzle, slide guide, diesel parts, metal molding, shaft wheels etc.
