Aluminum brazing is a versatile joining process widely used across various industries due to its ability to create strong, leak-proof, and corrosion-resistant joints. It is particularly favored for applications where lightweight materials with high thermal and electrical conductivity are required. The process involves joining aluminum parts using a filler metal that melts at a lower temperature than the base metal, ensuring minimal distortion and maintaining the integrity of the components. Below, we explore the key applications of aluminum brazing in detail.

Key Points Explained:
