Premium Silicon Bronze TIG Welding Wire | 1.6mm (1/16") | Copper Alloy Filler Rod
Product Description
This 1.6mm Silicon Bronze TIG filler wire is precision-manufactured for professional and hobbyist welders working with copper alloys, mild steel, galvanized steel, and dissimilar metal joints. Silicon bronze (also known as SiBr or ERCuSi-A) is a go-to choice for applications demanding excellent corrosion resistance, strong wetting characteristics, and a low melting point that reduces heat distortion on thin-gauge materials.
Composed primarily of copper with silicon and manganese additions, this filler wire delivers smooth, consistent arc characteristics and minimal spatter — making it a favorite among fabricators, automotive restorers, sculptors, and custom bike builders who need clean, braze-like welds with excellent tensile strength.
Key Features
- Diameter: 1.6mm (0.063" / 1/16") — ideal for thin to medium-gauge sheet metal
- Alloy Type: Silicon Bronze (ERCuSi-A)
- Process Compatibility: GTAW (TIG) welding
- Smooth Feed & Arc Stability: Consistent puddle control with minimal spatter
- Excellent Corrosion Resistance: Ideal for marine, automotive, and outdoor applications
- Low Melting Point: Reduces warping and heat-affected zone (HAZ) on thin materials
- Versatile Applications: Braze welding on galvanized steel, joining copper alloys, and dissimilar metal fabrication
Common Applications
- Automotive body panel repair and restoration (classic car fabrication)
- Custom motorcycle and bicycle frame building
- Galvanized steel and sheet metal fabrication
- Copper, brass, and bronze joining
- Artistic metal sculpture and fine metalwork
- Marine hardware and fittings
- HVAC and plumbing copper alloy repairs
Why Choose Silicon Bronze TIG Wire?
Silicon bronze filler wire is prized for producing ductile, crack-resistant welds with a distinctive gold-bronze finish that blends well aesthetically with brass and bronze base metals. Its lower melting temperature compared to steel fillers makes it especially effective for braze welding galvanized steel without burning off the zinc coating, and it's widely used where a strong yet flexible joint is required.
