Description
Compatible Base Materials
SifBronze No. 1 is a versatile brazing rod designed for joining a wide range of metals, making it ideal for applications such as:
- Ferrous Metals: Mild steel, carbon steel, cast iron, and galvanized steel
- Copper Alloys: Brass, bronze, and copper
- Dissimilar Metal Joining: Steel to copper, steel to brass, cast iron to steel
- Automotive Repair: Body panels, exhaust systems, and chassis components
- HVAC Applications: Pipe joints, tubing connections, and heat exchangers
- General Fabrication: Ornamental ironwork, furniture, and metal artwork
Standards & Specifications
- EN ISO 24373: S Cu 6560 (CuZn40Sn)
- AWS A5.8: RBCuZn-C
Typical Mechanical Properties
- Tensile Strength: 350-450 MPa
- Elongation: >25%
- Working Temperature: 830-890°C
- Shear Strength: 250-350 MPa
Key Features & Benefits
✅ Excellent Fluidity: Flows smoothly into joints, providing superior capillary action
✅ Tin Content: Enhances strength and corrosion resistance compared to standard brass
✅ Lower Working Temperature: Reduces base metal distortion and annealing
✅ Colour Match: Produces attractive golden-coloured joints, ideal for visible applications
✅ High Ductility: Joints resist cracking under stress or vibration
Recommended Flux and Techniques
- Flux Requirement: Must be used with appropriate bronze welding flux
- Flux Coverage: Apply flux to both rod and joint area for optimal results
- Heating Technique:
- Heat base metal evenly until flux becomes clear and active
- Touch rod to heated joint, allowing capillary action to draw material into joint
- Avoid overheating which can vaporize zinc and weaken the joint
Please note the rod length in the description above.
Arc Electrode rods (rough finish coating) are 300mm in length.
Tig filler rods (non arc) are sold in two formats;
- Packs of (x10, x20, x30, x40, x50, x100) are cut down from trade 1m lengths to 333mm. This is to reduce postage costs.
- 1kg, 2.5kg, 5kg are 1m, 1000mm original length.
Our prices include free shipping to the standard Royal Mail boundary postcodes (includes IOM, highlands, remote islands)!
Sorry we can’t afford the same to those outside this region.
