What Materials are Used in Welding Brazing? (9 Key Types Explained)

Welding brazing involves the use of various metals and alloys, each selected for specific properties such as melting point, wettability, strength, and corrosion resistance.

What Materials are Used in Welding Brazing? (9 Key Types Explained)

What Materials are Used in Welding Brazing? (9 Key Types Explained)

1. Aluminium-based Brazing Materials

Eutectic aluminium-silicon brazing material is widely used due to its good wettability, fluidity, and corrosion resistance. It is particularly favored in the aviation and aerospace industries for manufacturing complex aluminium structures.

2. Silver-based Brazing Materials

These materials have a low melting point and excellent wetting and caulking performance. They are versatile, capable of brazing almost all ferrous and non-ferrous metals. Elements like zinc, tin, nickel, cadmium, indium, and titanium are often added to enhance their properties.

3. Copper-based Brazing Materials

These are based on copper and include elements like phosphorus, silver, zinc, tin, manganese, nickel, cobalt, titanium, silicon, boron, and iron to lower the melting point and improve overall performance. They are extensively used in brazing copper and copper alloys, carbon steel, cast iron, stainless steel, high-temperature alloys, and hard alloys.

4. Nickel-based Brazing Materials

These materials are based on nickel and include elements like chromium, boron, silicon, and phosphorus to enhance thermal strength and reduce melting points. They are widely used in brazing stainless steel, high-temperature alloys, iron-based alloys, and diamond, among others, offering excellent resistance to high temperatures and corrosion.

5. Cobalt-based Brazing Materials

Typically based on Co-Cr-Ni, these materials are excellent for brazing cobalt-based alloys. The addition of silicon and tungsten can further enhance their properties, such as reducing the melting temperature and improving high-temperature performance.

6. Titanium-based Brazing Materials

Titanium, an active metal with high specific strength and excellent corrosion resistance, forms brazing materials with strong oxidation resistance and good wettability. These are used in vacuum brazing, diffusion brazing, and sealing for a variety of materials including titanium alloys, tungsten, molybdenum, tantalum, niobium, graphite, and ceramics.

7. Gold-based Brazing Materials

Comprising main alloy components like nickel, copper, palladium, zinc, indium, germanium, and tin, these materials are suitable for brazing copper, nickel, logable alloys, and stainless steel. They are particularly used in the aviation and electronics industries for critical components.

8. Palladium-based Brazing Materials

These are categorized into brazing materials for graded brazing in the electronics industry, high-temperature and heat-resistant brazing materials, and those with special properties. They are used in industries such as electric vacuum and aerospace.

9. Amorphous Brazing Materials

Developed through rapid cooling and quenching technology, these materials are used in various applications including plate-fin coolers, radiators, honeycomb structures, and electronic devices. They are available in nickel-based, copper-based, copper-phosphorus, aluminium-based, and tin-lead varieties.

Each of these materials is selected based on the specific requirements of the application, including the type of base metal, the environment in which the joint will operate, and the mechanical requirements of the joint. The choice of brazing material significantly impacts the integrity and performance of the brazed joint.
