High temperature brazing commonly utilizes materials such as aluminium-silicon alloys, silver-based alloys, copper-based alloys, nickel-based alloys, cobalt-based alloys, titanium-based alloys, gold-based alloys, palladium-based alloys, and amorphous brazing materials. Each of these materials has specific properties that make them suitable for different applications and environments.
Aluminium-Silicon Alloys: These are widely used in the aviation and aerospace industries due to their low density and high specific strength. Eutectic aluminium-silicon brazing material is particularly popular for its good wettability, fluidity, and corrosion resistance of brazed joints.
Silver-Based Alloys: Silver-based brazing materials offer a low melting point and excellent wetting and caulking performance. They are versatile and can be used to braze almost all ferrous and non-ferrous metals. Additives like zinc, tin, nickel, cadmium, indium, and titanium are often included to enhance their properties.
Copper-Based Alloys: These materials are based on copper and include elements like phosphorus, silver, zinc, tin, manganese, nickel, cobalt, titanium, silicon, boron, and iron to improve their melting point and overall performance. They are extensively used in brazing copper, carbon steel, cast iron, stainless steel, high temperature alloys, and hard alloys.
Nickel-Based Alloys: Nickel-based brazing materials are crucial for brazing stainless steel, high temperature alloys, iron-based alloys, and diamond, among others. They offer excellent resistance to high temperatures and corrosion, making them ideal for vacuum brazing applications.
Cobalt-Based Alloys: Cobalt-based brazing materials, typically Co-Cr-Ni based, are known for their high melting point and excellent mechanical properties. They are particularly suitable for brazing cobalt-based alloys and can be enhanced with elements like silicon and tungsten.
Titanium-Based Alloys: Titanium, an active metal with high specific strength and excellent corrosion resistance, forms brazing materials that are highly resistant to oxidation and have good wettability. They are used in vacuum brazing and diffusion brazing for a variety of materials including titanium alloys, tungsten, molybdenum, tantalum, niobium, graphite, and ceramics.
Gold-Based Alloys: Gold-based brazing materials are used for brazing copper, nickel, logable alloys, and stainless steel. They are particularly suitable for critical applications in the aviation and electronics industries due to their reliability and performance.
Palladium-Based Alloys: Palladium-based brazing materials are categorized into several types based on their applications, including graded brazing in the electronics industry and high-temperature brazing. They are used in industries such as electric vacuum and aerospace.
Amorphous Brazing Materials: These are developed through rapid cooling and quenching technology and are used in various applications including plate-fin coolers, radiators, honeycomb structures, and electronic devices.
Each of these materials plays a critical role in high temperature brazing, depending on the specific requirements of the application, such as temperature resistance, corrosion resistance, and mechanical strength. The choice of material is crucial for ensuring the longevity, reliability, and efficiency of the brazing process and the final product.
