Products Description
Metalized Ceramic is usually based on technical ceramics such as alumina (Al₂O₃), aluminum nitride (AlN), and zirconia. By forming a uniform, dense, and weldable metal layer on its surface, ceramic components can be firmly connected to metals such as Kovar, copper, and stainless steel. This product is not a simple "coated ceramic", but a functional component that has undergone process verification, structural design, and reliability evaluation. It is suitable for long-term service environments and has high requirements for air tightness, thermal conductivity, electrical insulation, and structural strength.
Core Product Advantages
Insulation and Conductivity
Ceramic Metallization ensures resistance to cracking under high-voltage or mechanical impact, maintaining the integrity of internal electrical circuits. The metallized layer enables ceramic components to be welded or bolted just like ordinary metal parts, solving the industry pain point that traditional ceramics cannot be directly installed, and achieving a perfect balance between insulation and conductivity.
High-Efficiency Heat Dissipation
The metallized layer greatly improves the thermal conductivity of ceramics. Relay cores or circuit breaker cores that need to withstand high-current impact in a short time can quickly dissipate heat, prevent component aging caused by excessive temperature, and significantly extend the service life of equipment. In the 100A load test, the heat dissipation efficiency of Ceramic to Metal is increased by more than 40% compared with pure ceramics.
Weather Resistance Protection
Metallization Ceramic has strong corrosion resistance after special treatment, and is not easy to rust even in humid or high-temperature environments, ensuring a long service life. The high temperature resistance (≥1200℃) and impact resistance of the ceramic matrix enable it to maintain stable performance under extreme working conditions, providing continuous protection for equipment operation.
Customized Adaptation
We support precision cutting and polishing of Precision Metallized Alumina Ceramic Components according to customers' CAD drawings to ensure a tight fit during assembly. Different ceramic matrices and metallized layer materials can be selected to adapt to different voltage levels and heat dissipation requirements, providing accurate safety solutions for high-voltage equipment.

Application Scenarios
Relay Iron Core
In relays, Metalized Ceramic Insulating Tubes Metalizating Ceramic Parts are often used as the terminal for fixing the iron core. It can not only conduct current but also prevent the iron core from arc breakdown caused by temperature rise, thus ensuring the reliable operation of the relay in high-voltage environments, and serving as a core safety component in power control systems.
Circuit Breaker Magnetic Core
For high-power circuit breakers, Metalized Ceramics for Electrical Components can withstand enormous electromagnetic force and achieve effective heat dissipation through its metal layer, protecting the main contacts of the circuit breaker from high-temperature damage and ensuring reliable breaking in the event of a short-circuit fault. It is an important safety guarantee for power distribution systems.
Intelligent Switch Module
In high-frequency switching power supplies, Metalized Ceramic is often used to support high-frequency transformers. While providing insulation performance, it effectively reduces the core temperature and ensures the stability of the module during high-frequency switching processes, which can be adapted to high-voltage power supply equipment in new energy, communications, and other fields.
