OVERVIEW

High-Performance 45% Silver Brazing Alloy

The Soudotec 6045K.16 is a premium-grade silver brazing filler metal designed for high-strength joining of ferrous and non-ferrous metals. Featuring a 45% silver content, this alloy is formulated to provide exceptional fluidity and capillary action, allowing it to penetrate tight clearances effectively. The 1.6mm (1/16 inch) diameter is versatile enough for delicate instrumentation work as well as general industrial piping. This specific variant comes flux-coated, integrating the necessary deoxidizers directly onto the rod, which streamlines the brazing process and ensures consistent wetting of the base metal surfaces.

Metallurgically, the high silver content lowers the melting range compared to lower-silver alloys, reducing the heat affected zone (HAZ) and minimizing distortion or grain growth in the base materials. This makes it particularly suitable for joining stainless steel, copper, brass, and bronze in various combinations. The resulting joints exhibit high tensile strength, excellent ductility, and superior corrosion resistance, often exceeding the mechanical properties of the base metals themselves. It is an excellent choice for applications involving vibration or thermal shock due to its inherent toughness.

This product is supplied in a convenient maintenance pack containing 6 sticks, each 12 inches in length. This packaging is optimized for MRO (Maintenance, Repair, and Operations) professionals who require high-quality consumables for sporadic repairs without the bulk of industrial kilogram-boxes. The flux coating is flexible and adheres well to the rod, preventing flaking during handling and ensuring that flux is delivered precisely where the alloy melts.

FAQ

Generally, no. These rods are flux-coated, which is sufficient for most clean joints. However, for dirty or heavily oxidized metals, applying a little extra silver brazing flux paste to the joint area before heating can help ensure perfect wetting.

You can join most ferrous and non-ferrous metals, including steel, stainless steel, copper, brass, and bronze. It is not suitable for aluminum or magnesium.

Yes, modern 45% silver alloys like this Soudotec product are typically cadmium-free, making them safer for the operator and suitable for food-grade applications.

Oxy-acetylene is the most common and effective method for silver brazing due to its high heat output. However, for small, thin parts, you can also use Oxy-Propane or MAPP gas torches.

While exact figures depend on the specific batch chemistry, 45% silver alloys typically have a melting range between 1125°F (607°C) and 1145°F (618°C).

45% silver flows much better, melts at a lower temperature, and is significantly more ductile. 15% is cheaper and good for copper-to-copper, but 45% is required for dissimilar metals and high-strength steel joints.

Yes, but you must remove the zinc galvanizing from the weld area first to ensure a good bond and avoid toxic fumes. The low melting point of the silver rod helps prevent burning the surrounding galvanization.

Store them in their original packaging in a dry, cool place. Moisture can damage the flux coating, causing it to flake off or absorb water, which leads to porosity in the braze.
