Choosing the Best Dip Brazing Alloy

Dip brazing is one among several different metallurgy techniques by which a specialist can join two metallic objects – joints – together, for whatever purpose.

Performing a successful dip braze is very simple in theory – all you need is a brazing alloy with a liquid point lower than that of the metals you’re joining (basically, a melting point where the metal is in a perfect liquid state as per Dictionary.com), a flux for the heating to occur in (salt, resin, and several other similar choices that do not affect or bond with metal outside of speeding up the production of an oxide layer), and the expertise to perform the actual brazing of the two metallic objects with the alloy. In practice, of course, hiring dip brazing services ensures that you get the job done.

Your choices, ultimately, for completing this task are very numerous. If you’re looking for a high-quality, highly corrosion-resistant choice, then soft noble metals like silver, gold and palladium are valid choices.

In the alloy department, you have a much wider variety of choices, such as:

  • Al-Si: This is aluminum mixed with silicon, the perfect brazing alloy for any aluminum joining that needs to be done.
  • Au-__: Gold is a great core metal to use for a number of alloy partners, including silver, copper, nickel, and palladium. These are used mostly in cases where you need corrosion resistance, or in jewelry.
  • Cu-Zn: Also known as brass, this combination of copper and zinc works well for most simple steel and cast iron joining needs, and is especially valuable for its ductile nature.

No matter what alloy you ultimately need to work with or choose to work with, it’s best to consult any number of dip brazing services in order to feel comfortable with your choice. Second, third and fourth opinions are always a good idea.
