Popular Uses for Tin Zinc Solders

Are you trying to decide if zinc solder would be right for your business? Zinc is useful in soldering applications that require lower temperatures. For example, if you wanted to solder aluminum or copper. The basic formulation is comprised of 70 percent tin and 30 percent zinc. Here at Belmont Metals in Brooklyn, we sell tin zinc solder in capping bar, ingot and 2mm wire.

Benefits of Tin Zinc Solders

Tin zinc solders are extremely advantageous in certain applications that require lower temperatures and need an extremely corrosion-resistant surface where flux cannot be or should not be used.

  • Lower operating temperatures than for zinc aluminum solders
  • Solder starts melting around 390 degrees
  • Great for soldering aluminum and copper
  • Inherently corrosion resistant
  • Excellent for use as a spray wire
  • Extremely high tensile strengths

Common Uses for Tin Zinc Solders

When we look at the common uses for zinc solder, they typically involve soldering metals and components that cannot be exposed to a high level of heat and where precision and delicacy are required in order to complete the job.

Soldering Aluminum to Aluminum or Copper to Copper

Tin Zinc solders can be effectively used to solder aluminum and copper. One of the ways to do that is with MAB rod, which has a melting point of 720 degrees Fahrenheit (382C). We recommend using an oxygen and gas fuel torch with a neutral or reducing flame for large projects and propane torches for smaller projects when soldering with MAB rod. It’s important to note that flux is not needed with MAB rod.

Repairing Electronic Components, Including Capacitors

Electronic components and capacitors require a light touch and precision work. For this detailed work, we typically recommend tin zinc soldering wire or spray wire, which has a low melting point and helps to avoid heat damage, including the deformation of sensitive components, especially where capacitors are concerned.

Soldering Repair Work that Requires Precision and Delicacy

Lower melting alloys are perfect for applications that require precision and delicacy. Precision and delicacy are primarily achieve using MAB rod. This is because preparation involves heating the surfaces that are to be joined instead of the rod. Once the surfaces reach the desired temperature, the MAB rod is scratched along the surface in order to deposit the liquid soldering metal.

Tin Zinc Solders from Belmont Metals

We offer tin zinc solders in a range of compositions. While the most common composition is 70 percent tin and 30 percent zinc, we also offer percentages of 91/9, 80/20 and 60/40 to meet all of your precision soldering needs where a high tensile strength is needed to ensure the durability of the joined components. In addition to tin zinc solders, we also offer tin lead solder alloy and aluminum solder.
