Which metals can commonly be joined using silver brazing?

Silver brazing is a technique known for its effectiveness in joining metals with a strong, durable bond. The method utilizes a filler metal, typically containing silver, that has a melting point higher than 450°C (about 840°F). This allows the filler metal to flow between the workpieces, creating a strong joint upon cooling.

Copper, brass, and steel are commonly joined using silver brazing due to their thermal and chemical properties. Copper and brass are metals that braze well with silver because the high heat resistance of the brazing alloy complements the thermal conductivity of these materials. Steel, while different in composition, can also be successfully joined to these metals, allowing for a versatile application of silver brazing.

The other choices consist of pairs of metals that either have very different melting points, surface oxides that are difficult to manage during the brazing process, or are not typically used together in practice. For example, gold and titanium require specialized techniques for joining due to their unique characteristics. Similarly, aluminum and magnesium are generally not brazed using conventional methods because they require processes that can handle their particular reactivity and melting behavior. Iron and lead have similar challenges, as the fusion of these metals does not lend itself well to the silver brazing process
