What can I use for a brazing rod?

Recommended Rods by Metal Type

  • Copper, brass, bronze: Copper Phosphorous Brazing & Welding Rods.
  • Steel, stainless steel, nickel alloys, copper alloys, cast iron, tungsten carbide: Nickel Silver Brazing & Welding Rods.
  • Cast iron, galvanized, nickel, steel, malleable iron: Bronze Brazing & Welding Rods.
  • Aluminum:

Which brazing rod is the strongest?

The strongest brazing rod made for joining cast iron and steel, HTS-528 is thin flowing for close-fit joining and repairs on all cast iron, steel, copper, bronze, nickel, and brass. It also will effectively join dissimilar metals.

What is the most common brazing rod?

The most common rods used for typical HVAC brazing are 0%, 5%, and 15%, with several other levels mixed in there. The percentage is the percentage of silver content in the rod.

Can you braze with a propane torch?

Brazing permanently joins two metals using a torch. You can use a propane torch to braze most metals you want to join. Propane torches are widely available in your local hardware stores, plumbing supply houses as well as at metalsmith and jewelry supply companies.

Can you braze with stick welder?

MIG welders can do many things, but they cannot heat metal for bending or brazing. Your stick welder can do those things with a carbon arc torch added to it.

What is the most commonly used flux for brazing?

Borax
Borax-based fluxes: In addition to being a common ingredient in detergents and many other products, borax has long been used as a flux in welding processes, including brazing. Borax improves the flow of filler metals and reacts with certain oxides to lower their melting points.

Can I use soldering flux for brazing?

Yes. It is imperative to use flux for the following reasons: Removes oxides from metals to be joined (you will still need to clean your metals prior to application). Prevents oxidation after completion.

Is brazing as strong as a weld?

Comparative Advantages. First, a brazed joint is a strong joint. A properly made brazed joint (like a welded joint) will in many cases be as strong or stronger than the metals being joined. Second, the joint is made at relatively low temperatures, ranging from about 1150°F to 1600°F (620°C to 870°C).

Why is silver used for brazing?

Adding silver to the process of soldering or brazing helps produce smooth, leak-tight, electrically conductive and corrosion-resistant joints.

Can you use MAPP gas to braze?

The problem with the larger, cooler flame common to standard air-Mapp gas rigs is: Not only is it limited to brazing smaller components and smaller copper tube sizes, but it takes longer and results in more heating of the surrounding area, which does more damage to heat-sensitive parts.

What is a brazing rod used for?

Brazing is typically used when joining pieces of the same metal type, such as steel to steel or copper to copper. Brazing rods are pieces of metal that melt during the welding process and attach to the separate pieces of metal to join them together once cooled.

What is a brazing strip made of?

These alloys are also known as trimetal brazing strips. They have silver with nickel alloy sides and a copper core. Also known as trimetal brazing strips, these alloys have silver with nickel alloy sides and a copper core.

What determines the thickness of a brazing rod?

The thickness of the brazing rod depends both on how thick the material to be joined is and the kind of metal it is. A thick piece of material, for example, typically requires a thicker brazing. If the rod is too thin, it will melt before the metal pieces are hot enough to accept the weld.

What is a TriMetal brazing strip?

These alloys are also known as trimetal brazing strips. They have silver with nickel alloy sides and a copper core. Also known as trimetal brazing strips, these alloys have silver with nickel alloy sides and a copper core. These rods create stronger welds than standard TIG welding rods for aluminum.
