What materials can be joined by brazing?

Brazing can join a variety of metals, including steel, copper, aluminum, brass, and nickel alloys. It is particularly effective for dissimilar metals, allowing for strong, durable joints. The process involves melting a filler metal with a lower melting point than the base metals, which then flows into the joint by capillary action. Additionally, brazing can be used for certain ceramics and some plastics when appropriate filler materials are used.
