Bernzomatic NS3 Nickel-Silver Flux Coated Brazing/Welding Rods, 2-Piece , Blue

The Bernzomatic NS3 Nickel-Silver Flux Coated Brazing/Welding Rods are a versatile option for joining various metals together. Whether it's mild steel, stainless steel, brass, or copper, these rods can be used with the proper flux to create strong and durable bonds. One customer used these rods to braze stems to leaves for art purposes. While the welds weren't a perfect silver color, they could be smoothed with a small grinder to achieve a more silvery appearance. Another customer used the rods to solder a choke onto a shotgun barrel, but mentioned the need for high temperatures that may affect the temper of the barrel. When it comes to brazing stainless steel, the proper flux is crucial. The blue flux provided with the rods is not recommended, but the Harris Stay silv black flux, along with a flux brush, is highly recommended. It is important to heat both pieces of stainless steel simultaneously and apply the rod to the base metal when it reaches an amber color. The diameter of the metal part of the rods is estimated to be 1/8" or less, and they flow similarly to old nickel/silver rods. Customers have successfully used these rods to attach brass to steel, and one customer mentioned using them to braze a O2 bung in stainless headers. While the Q&A section provided useful information about the product, there were also some unanswered questions, including the percentage of nickel in the rods. In terms of customer reviews, opinions were mixed. Some customers found the rods to work well for their intended applications, such as knife making and connecting copper to stainless steel. However, others encountered difficulties, such as having a hard time using them with a MAPP torch or not achieving the desired melting point. One customer was disappointed with the quantity, as the package only contained two brazing sticks. Overall, the Bernzomatic NS3 Nickel-Silver Flux Coated Brazing/Welding Rods have the potential to be a valuable tool for joining various metals together, but users should be mindful of the specific requirements and techniques needed for each application.
