The most commonly used filler metal in brazing is silver-based filler metals. This choice is supported by their versatility and effectiveness in various brazing applications, particularly due to their ability to provide strong joints and good corrosion resistance.
Silver-based filler metals are widely used in brazing due to several key advantages:
- Strength and Durability: Silver-based filler metals offer high strength and durability, making them suitable for applications requiring robust joints. The mechanical properties of joints made with silver-based filler metals are typically superior to those made with other types of filler metals like tin-lead solder, which is primarily used for soft brazing and in applications with low load-bearing requirements.
- Corrosion Resistance: Silver has inherent corrosion resistance, which is beneficial when brazing metals that are also corrosion-resistant, such as stainless steel. This ensures that the brazed joints maintain their integrity over time, even in harsh environments.
- Thermal and Electrical Conductivity: Silver is an excellent conductor of both heat and electricity. This property is advantageous in applications where thermal or electrical conductivity is crucial, such as in electronic components or heat exchangers.
- Wetting Ability: Silver-based filler metals have good wetting properties, meaning they spread evenly and adhere well to the base metals being joined. This ensures a uniform and strong bond during the brazing process.
In contrast, other filler metals like tin-lead solder are more limited in their applications due to their lower strength and are typically used only for soft brazing where the load-bearing requirements are minimal. The reference provided also mentions other types of filler metals such as copper-based, manganese-based, nickel-based, and precious metal filler metals, each with specific applications and properties. However, silver-based filler metals are noted for their broad applicability and superior performance characteristics, making them the most commonly used in brazing.
Overall, the selection of filler metal in brazing is critical and depends on the specific requirements of the materials being joined and the desired properties of the final assembly. Silver-based filler metals, with their combination of strength, corrosion resistance, and conductivity, are well-suited for a wide range of brazing applications.
