Brazing Filler Metals / Alloys for Brazing Processes

Brazing is a group of joining processes that allow materials to be fused together by heating them to a brazing temperature in the presence of a brazing filler metal. This metal has a liquidus temperature above 840°F and below the solidus temperature of the base metal. The filler metal flows into the joint through capillary action, creating a strong and reliable bond.

Shree Kailaji Alloys, a trusted Brazing Filler Wire Manufacturer, Supplier in India, provides a complete range of brazing alloys and fluxes for various industrial applications. Our products are designed for durability, precision, and consistent performance across multiple industries.

Our Range of Brazing Alloys

Silver Brazing Alloys With Cadmium

We offer high-quality cadmium-bearing alloys with an excellent combination of melting range, capillary flow, and mechanical strength. These alloys are cost-effective solutions where the presence of cadmium is acceptable.

Silver Brazing Alloys Without Cadmium

Understanding the needs of industries like food and beverage, we supply cadmium-free alloys suitable for most ferrous and non-ferrous metals. These are available in multiple forms, including wire, strip, powder, paste, preforms, clad tri-metal products, and flux-cored wires.

Silver Brazing Alloys for Tungsten Carbide Tipped Tools

We manufacture specialized nickel-containing brazing filler metals for tungsten carbide tipped tools. These alloys provide protection from crevice corrosion and perform well at high temperatures. Available in wire, foils, or shims, they meet stringent industrial standards.

Silver Copper Phosphorus Brazing Alloys

Our copper phosphorus alloys are perfect for refrigeration, air conditioning, and plumbing industries. They are widely used to join copper and copper alloys such as brasses and bronzes. These alloys are self-fluxing on copper and are available in wires, strips, wire flattening, preforms, granules, and spheres. Custom solutions are also provided based on your requirements.

Copper Based Brazing Alloys-Brasses And Bronzes

TWe supply general-purpose brasses, brasses with added nickel, high-temperature copper alloys, and furnace brazing copper. These alloys are economical, versatile, and can be supplied in rods, wires, preforms, strips, powders, and pastes. They are ideal for Oxy-Fuel Gas Braze-Welding processes.

Fluxes
We manufacture a wide variety of fluxes suitable for different applications. These include mild organic acids or strong inorganic acids that promote fast cleaning of metals with strong surface oxides. Our fluxes are commonly used in silver brazing, copper brazing, soldering, and aluminium welding.
