Brazing is a method of joining two pieces of metal together by using a filler metal. This technique of metal joining provides greater mechanical strength than soldered joints.
The filler metal material for brazing comes in the form of a brazing rod. The rod is melted and is used to provide a strong joint between the two metal pieces.
Brazing alloys flow at 1175° to over 1700°F which helps to provide the heat and strength needed in joining two pieces of heavy metal together.
What is the best brazing rod material for your specific job? Below are some of the best Brazing Rod types that can help you with your job:
The Sil-Fos Brazing Rods:
The Sil-Fos family of alloys is made mostly of copper with a little Phosphorous added, usually containing various amounts of Silver. When joining copper-to-copper parts the phosphorous serves as the fluxing agent and therefore does not require a separate liquid flux.
Both the Sil-Fos 5 and 15 have Silver added for additional gap filling of parts.
Best Brazing Sil-Fos 15 Brazing Rods, 1 LB Tube, Lucas-Milhaupt 95150
This is the 15% Silver bearing alloy designed for general purpose brazing with large gaps. This silver brazing alloy is ideal for copper-to-copper joints as the phosphorus in the Sil-Fos serves as the fluxing agent.
This brazing rod alloy material is great for joining copper, brass, and bronze products. It has the highest durability of the Sil-Fos products.
With brass, a fluxing agent is recommended.
Sil-Fos 15 contains 80% Copper/ 15% Silver/ 5%P phosphorous.
This alloy has a solidus of 1190°F, a liquidus of 1475°F and a flow point of 1300°F.
- Sil-Fos 15 Brazing Alloy containing 15% Silver
- Sil-Fos 15 alloy has Solidus of 1190°F, Liquidus of 1475°F, flow point of 1300°F
- Flat Rods measure 0.050" thick x 0.125" wide x 20" long
Sil-Fos 5 Brazing Rods, 1 LB Tube, Lucas-Milhaupt 95060
This is the 5% Silver bearing alloy designed for general purpose brazing with large gaps (and where close fit-ups can’t be maintained. For copper-to-copper joints, the phosphorous in the Sil-Fos serves as the fluxing agent and you won’t have to use a separate flux. This Sil-Fos 5 brazing rod material is best used for joining copper to brass to bronze products.
Sil-Fos 5 brazing rods contain 89% Copper/5% Silver/6% Phosphorous.
This alloy has a solidus of 1190°F, a liquidus of 1495°F and a flow point of 1325°F.
- Sil-Fos 5 Brazing Alloy containing 5% Silver
- Sil-Fos 5 alloy has Solidus of 1190°F, Liquidus of 1495°F, flow point of 1325°F
- Flat Rods measure 0.050" thick x 0.125" wide x 20" long
Fil Fos-Flo #0 Brazing Rods. 1 LB Tube, Lucas 95000
The Fos-Flo copper brazing rods are the most economical of the brazing alloys designed for general purpose brazing on well-fitted joints with small gaps of .001" to .003".
Also known as #0 Brazing Alloy - Fos-Flo 7 contains no Silver. You can use the Fos-Flo to join copper, brass and bronze products. Fos-Flo 7 contains 92.75% Copper and 7.25% Phosphorous.
It is the economical choice and a great choice for a very medium temperature filler.
This alloy has a solidus of 1310° F, a liquidus of 1460 °F and a flow point of 1350° F.
