Composite BN-AlN Ceramic Description

Boron Nitride Composite Ceramic BN-AlNBoron Nitride is a kind of advanced synthesis ceramic that was sintered at a high temperature and high pressure by BN powder. It has many excellent properties including high-temperature resistance, high thermal conductivity, easy machining, and good lubricity, making BN an outstanding material.

Boron nitride composite BN-AlN ceramic is manufactured by a transitional plastic phase process. The relative density of the hot-pressed composite ceramic decreases as the boron nitride content increases, but 30% of the boron nitride can be obtained in more than 99% of the aluminum nitride. Though materials such as quartz are not available in high-temperature gas atmospheres, boron nitride-aluminum nitride composite ceramic gears provide reliable drive performance.

•  High hardness, excellent wear resistance

•  High mechanical strength, high thermal conductivity

•  Provide a reliable driving force for gears

Good quality and doesn't break with a light crash.
