36SILBR035 - ERCuSi-A Silicon Bronze TIG Rod .035 x 36"

Premium Silicon Bronze TIG Rods for Versatile Fabrication

Unlock the potential of versatile metal joining with our Silicon Bronze TIG Welding Rods. Sized at a precise 0.035-inch diameter and cut to industry-standard 36-inch lengths, these rods are engineered for welders who demand control and quality. Silicon Bronze (AWS ERCuSi-A) is a copper-based filler metal containing approximately 3% silicon and small amounts of manganese, tin, and zinc. This unique composition makes it a favorite among fabricators for its ease of use and exceptional fluidity.

One of the standout applications for this filler metal is TIG Brazing. Unlike traditional welding which melts the base metal, TIG brazing uses the silicon bronze to join metals at lower temperatures. This is particularly advantageous when working with galvanized steel, as the lower heat input minimizes the burning off of the protective zinc coating, maintaining the corrosion resistance of the base material. It also significantly reduces warping and distortion, making it the go-to choice for automotive bodywork and thin sheet metal fabrication.

Beyond automotive applications, these rods are essential for artists and sculptors. The deposit has a rich, gold-like bronze color that is aesthetically pleasing and polishes well. It is also the primary choice for welding copper-silicon alloys and can be used to join copper to steel. Whether you are repairing a cast iron part, fabricating a custom exhaust, or creating a metal sculpture, these Silicon Bronze rods provide a smooth, clean bead with excellent crack resistance.

Key Benefits for Your Workshop

• Versatile Joining: Capable of joining copper, brass, bronze, and steel.


• Corrosion Resistant: Excellent resistance to corrosion, making it suitable for marine environments and overlay applications.


• Low Heat Input: Ideal for thin materials where distortion control is critical.


• Clean Welds: The silicon content acts as a deoxidizer, helping to remove impurities and ensure sound, porosity-free welds.
