Brazing is a versatile joining process used across a wide range of industries due to its ability to create strong, durable, and leak-proof joints between dissimilar materials. It is particularly valued in industries where precision, reliability, and high-performance materials are required. The process involves heating a filler metal above its melting point and distributing it between two or more close-fitting parts by capillary action. This method is widely used in industries such as automotive, aerospace, HVAC, electronics, and medical devices, among others. Below, we explore the key industries that rely on brazing and the specific applications within each sector.
