03SIB30 - Harris ERCuSi-A Silicon Bronze TIG Rod 1/16" x 36" (10lb Tube)

Harris Silicon Bronze TIG Rod 1/16" - 10lb Tube

The Harris Silicon Bronze TIG Rod is a premium copper-based filler metal designed for a wide range of welding and brazing applications. Packaged in a convenient 10lb tube, these 36-inch cut lengths are an essential consumable for professional fabricators and maintenance shops alike. With a diameter of 1/16" (1.6mm), this rod offers precision control for detailed work while providing enough deposition for structural repairs on compatible materials.

Known for its versatility, this ERCuSi-A classified rod is primarily used to weld similar base metals such as copper, brass, and bronze. However, its utility extends far beyond simple copper alloy welding. It is an excellent choice for joining dissimilar metals, specifically steel or cast iron to copper alloys. This capability makes it indispensable for repair work where matching the exact base metal chemistry is difficult or where a ductile transition joint is required.

One of the standout features of the Harris Silicon Bronze rod is its effectiveness in "braze welding" coated sheet steels. When working with galvanized steel, standard steel welding rods can burn off the protective zinc coating and cause excessive fuming and porosity. Silicon Bronze melts at a lower temperature (Liquidus 1880° F), allowing the operator to join galvanized sheets with minimal disturbance to the zinc coating, resulting in a cleaner, more corrosion-resistant joint. It is also widely used for surfacing areas subjected to corrosion, adding a protective layer to steel components.

This rod is designed for use with DC- straight polarity and requires 100% Argon shielding gas to produce clean, high-quality welds. With a minimum tensile strength of 50,000 psi, it ensures that repairs and fabrications are robust and reliable. Whether you are working on metal art, automotive repairs, or industrial maintenance, the Harris Silicon Bronze TIG Rod delivers consistent performance and high-quality results.
