silver brazing rods

Hook:
In brazing applications, achieving a balance between joint performance, process compatibility, and cost is a primary consideration. Silver-based filler metals offer a range of melting and flow characteristics to address different material combinations and design requirements.
Product Overview:
We supply a range of silver brazing filler metal rods (silver brazing rods), available in standard straight lengths of 500mm and diameters of 1.0mm, 1.5mm, 2.0mm, 2.5mm, and 3.0mm, packaged in 1 kg boxes. We also support custom manufacturing of other specifications based on confirmed customer orders. Our silver brazing rods, also known as silver solder rods, feature low melting point.
