Description
High Quality Manufacture Silicon Nitride Ceramic Sleeves
Silicon nitride ceramic sleeves have better high temperature capabilities than most metals combining retention of high strength and creep resistance with oxidation resistance.
Size: as your requirements.
Delivery time: depend on the quantity.
Materials：95%,99.9%Alumina (Al2O3)ceramic/ Zirconia(ZrO2) ceramic /Silicon nitride ceramic(Si3N4) /Silicon Carbide ceramic/AIN ceramic.
Application:Silicon Nitride Ceramic Rods/Pistons/Sleeves usually used in the engine components, bearings and cutting tools.
Note: The shape(outter diameter&length) of ceramic rods/pistons/ sleeves, surface roughness and tolerance can be customize.
Advantages:
Silicon nitride ceramic’s excellent thermal conductivity and thermal shock resistance make it a preferred material for applications requiring efficient heat dissipation and resistance to thermal stress, such as in the production of heat sinks for electronic devices and components for high-power electronic circuits.
