Low thermal expansion and strong against thermal shock, Kogilight.
This is an insulating ceramic characterized by being lightweight and having a low thermal expansion rate, excelling in thermal shock resistance. It exhibits less than half the thermal expansion rate compared to common materials like alumina. It is used in applications where dimensional changes due to temperature fluctuations must be minimized, or as insulating materials that experience rapid temperature changes. Our company conducts consistent manufacturing from material procurement to production at our raw material factory. We respond to requests such as "The machine parts currently in use have been discontinued and cannot be procured" and "I want it made in shapes, strengths, and specifications that are not available in existing products." Examples of applications: ■ Automotive parts ■ Fuse cases ■ Automotive catalysts
