The Introduction and Applications of Ceramic-Metal Brazed Joints

July 11, 2023

Ceramic-metal brazing is a specialized joining technique that allows for the seamless fusion of ceramics and metals. This process enables the creation of strong and reliable joints, making it invaluable in various industries where the unique properties of both ceramics and metals are required. In this article, Xiang Ceramics will explore the basic principles of #ceramic-to-metal brazing and discuss its wide range of applications based on many years of experience in production and R&D. 


1. Ceramic-Metal Brazed Joints

Ceramic-metal brazed joints are created by heating a combination of ceramic and metal components with a suitable brazing material. The brazing material, often a filler alloy compatible with both the ceramic and metal, melts and forms a metallurgical bond at the interface, effectively joining the two materials. The brazed joint maximizes the mechanical strength and thermal compatibility between ceramics and metals, offering a range of unique advantages.

2. Advantages of Ceramic-Metal Brazed Joints

· High Strength: #Ceramic-metal brazed joints exhibit high tensile and shear strength, making them suitable for demanding applications where mechanical integrity is critical.

· Thermally Compatible: Unlike traditional adhesive bonding methods, ceramic-metal brazed joints maintain their strength and integrity at high temperatures, allowing for applications in thermal management systems or high-temperature environments.

· Hermetic Seal: The metallurgical bond created during brazing ensures a hermetic seal, making ceramic-metal brazed joints ideal for applications requiring gas-tight or vacuum seals.

· Electrical Conductivity: Certain ceramic-metal combinations can provide electrical conductivity, expanding the possibilities for electronic and electrical applications.


3.  Applications of Ceramic-Metal Brazed Joints

· Electronics: Ceramic-metal brazed joints are widely used in the electronics industry. They enable the integration of electronic components with ceramic substrates, providing electrical connectivity and mechanical support.

· Aerospace: The high strength and thermal compatibility of ceramic-metal brazed joints make them extensively used in the aerospace industry. Applications include turbine blades, engine components, and heat exchangers.

· Automotive: The automotive industry benefits from ceramic-metal brazed joints in applications such as exhaust systems, catalytic converters, and sensors. The joints provide excellent thermal resistance and structural integrity.

· Medical: Ceramic-metal brazed joints find applications in medical devices, such as implants and prosthetics, due to their biocompatibility, strength, and corrosion resistance.

· Energy: Ceramic-metal brazed joints play a vital role in energy conversion and storage systems. They are used in solid oxide fuel cells (SOFCs), solar cells, and battery assemblies.


Ceramic-metal brazing provides a universal and reliable method for joining ceramic and metal parts. The ceramic metal brazed parts produced by Xiang Ceramics were shown high strength, good thermal compatibility, and usually have electrical conductivity, etc. These are the key points of ceramic - metal brazing joints which used in various industries. Our #ceramic metal sealing parts are widely used in electronics, aerospace, automotive, medical and energy. With the continuous development of the era of science and technology, ceramic-metal brazing will undoubtedly continue to find new applications in emerging fields.
