When it comes to brazing, the most commonly used filler metal is silver-based filler metals.
These are popular because they are versatile and effective in many brazing applications.
One of the main reasons for their popularity is their ability to provide strong joints and good corrosion resistance.
What is the most commonly used filler metal in brazing? (4 Key Advantages)
1. Strength and Durability
Silver-based filler metals offer high strength and durability.
This makes them ideal for applications that require robust joints.
The mechanical properties of joints made with silver-based filler metals are usually better than those made with other types of filler metals, like tin-lead solder.
Tin-lead solder is mainly used for soft brazing and in applications with low load-bearing requirements.
2. Corrosion Resistance
Silver has inherent corrosion resistance.
This is beneficial when brazing metals that are also corrosion-resistant, such as stainless steel.
It ensures that the brazed joints maintain their integrity over time, even in harsh environments.
3. Thermal and Electrical Conductivity
Silver is an excellent conductor of both heat and electricity.
This property is very useful in applications where thermal or electrical conductivity is important.
Examples include electronic components or heat exchangers.
4. Wetting Ability
Silver-based filler metals have good wetting properties.
This means 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.
They are typically used only for soft brazing where the load-bearing requirements are minimal.
The reference also mentions other types of filler metals such as copper-based, manganese-based, nickel-based, and precious metal filler metals.
Each has specific applications and properties.
However, silver-based filler metals are noted for their broad applicability and superior performance characteristics.
This makes 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.
