Wear resistant insulation silicon nitride precision ceramic screw

Wear resistant insulation silicon nitride precision ceramic screw is a high-performance fastener made of advanced ceramic material – silicon nitride (Si ∝ N ₄). Silicon nitride ceramics have become an ideal material for manufacturing precision screws due to their excellent wear resistance, high hardness, good insulation performance, and outstanding high temperature and corrosion resistance. This product is designed for fields that require extremely high material performance, such as electronics, aerospace, medical equipment, chemical industry, etc., to meet the needs of fasteners that require both high-strength connections and insulation, wear resistance, corrosion resistance, and other characteristics.

Main characteristics
Wear resistance: Silicon nitride ceramics have a hardness second only to diamond and cubic boron nitride, and have extremely high wear resistance. Even in extremely harsh working environments, they can maintain long-term dimensional stability and service life.
Insulation: Silicon nitride ceramics are excellent electrical insulators with high resistivity, which can effectively isolate current and are suitable for applications that require electrical isolation.
High temperature resistance: Silicon nitride ceramics have no melting point under normal pressure and can maintain stability at temperatures up to 1800 ℃. They have a low coefficient of thermal expansion and good thermal shock resistance, making them suitable for use in high-temperature environments.
Corrosion resistance: Silicon nitride ceramics have excellent corrosion resistance to various chemicals, and are almost unaffected by other acids, bases, and salt solutions except for hydrofluoric acid and concentrated sodium hydroxide.
High precision: Adopting precision ceramic processing technology to ensure the dimensional accuracy and thread quality of screws, meeting the requirements of precision assembly.
