36SILBRO45 - Silicon Bronze TIG Welding Rod 0.045 ERCuSi-A

Premium Silicon Bronze TIG Rods for Versatile Fabrication

Unlock the versatility of copper-alloy welding with our 0.045" Silicon Bronze TIG Rods. Packaged in a convenient 10 lb tube, these 36-inch cut lengths are an essential consumable for fabricators, artists, and automotive restoration experts. Silicon Bronze (ERCuSi-A) is a copper-based filler metal containing roughly 3% silicon and small amounts of manganese, tin, and zinc. This unique composition provides excellent corrosion resistance and high strength, making it a top choice for projects requiring durability and aesthetic appeal.

One of the standout features of this filler metal is its ability to join a wide variety of base metals. It is the go-to rod for welding copper, brass, and bronze to themselves or to steel. Additionally, it is widely used in the automotive industry for "TIG brazing" sheet metal and galvanized steel. Because it melts at a lower temperature than steel, it minimizes heat distortion and burns away less of the protective zinc coating on galvanized parts compared to standard steel welding. Whether you are creating metal sculptures, repairing marine components, or performing delicate bodywork, these rods deliver smooth, clean beads with minimal spatter.

At Josef Gas, we ensure our consumables meet strict quality standards. These rods are clean, consistent, and ready for precision work. The 0.045" diameter is perfect for fine detail work and thinner gauge materials where heat control is paramount. Stored in a durable tube, your rods remain straight and protected from moisture and contaminants until you are ready to weld.
