Products Description

Metalized Ceramics for Electrical Components are fabricated by coating a layer of metallic material on the ceramic surface. Ceramics themselves feature excellent electrical insulation, high-temperature stability and chemical corrosion resistance, while the metallized layer endows them with electrical conductivity and solderability, enabling a wider range of applications.

We focus on providing customers in fields including industrial control and new energy with high-performance, customizable Ceramic Components with Metallization products and one-stop supporting solutions. With material technology, precision manufacturing, and in-depth services, we help customers improve product quality, reduce supply chain costs, and shorten development cycles.

Core Product Advantages

Integration of Insulation and Conductivity

Metal Coated Ceramic Parts integrate insulation and conductivity. The ceramic substrate ensures reliable insulation, suitable for high-voltage and high-frequency applications; the surface metallization layer delivers stable conductivity and enables direct soldering. The integrated structure simplifies packaging and solves the pain point of traditional substrates that "cannot achieve both insulation and conductivity".

High Temperature Resistance and Corrosion Resistance

The substrate of Metallized Ceramic Assemblies provides excellent high-temperature resistance, allowing long-term stable operation in high-temperature environments. Meanwhile, it features corrosion resistance and oxidation resistance, protecting against harsh environments, extending component service life, and reducing maintenance costs.

Excellent Thermal Conductivity

Ceramic–Metal Bonded Components boast outstanding thermal conductivity, enabling rapid heat dissipation and effective temperature control of components. This greatly improves the operational stability and service life of high-power electronic components, meeting thermal management requirements.

High Bonding Strength

Alumina Ceramic with Metallized Coating adopts advanced metallization processes to achieve metallurgical bonding between the metal layer and ceramic, with strength far exceeding that of traditional processes. They can withstand vibration, impact and thermal shock, ensuring reliable operation of components under extreme working conditions.

Ceramic Components with Metallization

Material Advantages

Ceramic Matrix Materials: Ceramic Parts with Metallized Surface prefer high-performance ceramics suitable for the electronics sector, which mainly fall into three categories:

Alumina ceramics: Cost-effective, suitable for conventional medium-low voltage and medium-power components.
Beryllia ceramics: High thermal conductivity, ideal for high-power and high-frequency devices.
Aluminum nitride ceramics: Eco-friendly and low-expansion, used in high-end fields such as new energy and aerospace.

Metallization Layer Materials: Ceramics with Metal Coating adopt four types of high-purity materials: tungsten, molybdenum, copper, and silver.

Tungsten and molybdenum layers: High temperature resistance and strong bonding strength, suitable for high-temperature and high-pressure working conditions.
Copper layer: Excellent electrical and thermal conductivity, easy to weld, meeting medium-low temperature and high-conductivity requirements.
Silver layer: Superior electrical conductivity and low contact resistance, suitable for high-frequency precision devices.

Auxiliary Materials: High Temperature Metallized Ceramic Components all use eco-friendly products free of hazardous substances, complying with international environmental standards. Special binders and sintering additives enhance the bonding strength of ceramic metallization. Matching solders ensure reliable welding, effectively avoiding cold joints and de-welding, and improving the corrosion resistance and service life of products.
