Key Features of Silicon Carbide Products

As a type of high-performance ceramic materials, silicon carbide products exhibit excellent properties in multiple industrial fields and provide strong support for the development of advanced technologies. The following are the key properties of silicon carbide products that make them the material of choice in many areas due to their excellent performance under extreme conditions such as high temperatures, pressures and corrosion.
High temperature stability
Silicon carbide products have attracted attention due to their excellent high-temperature stability. In extreme high temperature environments, it can maintain structural stability and performance and is not prone to brittleness or deformation. This makes silicon carbide products ideal for high-temperature processes, furnace components and aerospace applications. The high-temperature stability of silicon carbide products provides engineers with broader design flexibility in manufacturing high-temperature resistive materials and other applications that require high-temperature performance.
High hardness
Silicon carbide is known for its exceptional hardness, far exceeding that of many traditional engineering materials such as steel and aluminum. This hardness makes silicon carbide products excellent in resistance to wear and corrosion, making them suitable for manufacturing demanding parts such as brake discs, cutting tools and abrasive tools. In manufacturing, the high hardness of silicon carbide products provides critical support for improving component durability and performance.
Excellent thermal conductivity
