Ceramics that can withstand rapid temperature increases and decreases while maintaining electrical insulation! They are used in fuses that require high currents, such as in electric vehicles.
At Otsuka Ceramics, we manufacture "Kojilight" products. Kojilight is a relatively inexpensive ceramic. It is characterized by a low coefficient of thermal expansion and excellent resistance to thermal shock. It is used in automotive exhaust system components, fuses for electric vehicles, and infrastructure facilities that require high current. Additionally, it has perfect anti-soiling measures due to self-glazing. *Please download the PDF to check the results of the thermal shock resistance test. Since our establishment in 1959, our company has a wealth of experience in ceramic manufacturing and offers "custom-made ceramic products." We can accommodate a wide range of production from small lot production starting from one piece to mass production using molds. We conduct integrated production from raw material formulation to shaping, firing, processing, and inspection, and can propose manufacturing methods tailored to your needs. Prototyping is also possible. **Characteristics of Ceramics** - Usable in environments over 1,000°C - Higher insulation than general resins - Excellent chemical resistance - Adopted in a wide range of fields, including mechanical parts ★ We are distributing materials that outline the properties and characteristics of ceramic materials! You can view them from the [PDF download].

basic information
This is an insulating ceramic characterized by its lightweight and low thermal expansion rate, which excels in thermal shock resistance. It exhibits less than half the thermal expansion rate compared to common alumina and is used in applications where dimensional changes due to temperature fluctuations need to be minimized, as well as in insulating materials subjected to rapid temperature changes.
