Selectarc BRAZARGENT 3050

BRAZARGENT 3050 is a low-melting silver-based brazing alloy enriched with Nickel (Ni) which significantly improves its wettability, particularly for challenging materials such as Tungsten Carbide and difficult-to-wet metals like Molybdenum, Tantalum, and Chromium. It enhances joining strength and notably improves corrosion resistance on stainless steel compared to many standard silver brazing alloys. The alloy’s low flow point minimizes stainless steel oxidation during brazing. This versatile alloy is available in bare rods, coated rods (with HP Flux), and TBW (Tubular Brazing Wire) formats, offering flexibility in application. The inclusion of Silicon (around 0.1%) during melting contributes to the alloy’s stability and brazability, preventing unwanted sparking. A controlled quench (above 300°C) is essential to strengthen the brazed joint and avoid weakening. BRAZARGENT 3050 is ideally suited for brazing 300 Series Stainless Steel and is frequently utilized for joining Tungsten Carbide inserts to Steel and Tool Steel for cutting tools. It’s a capable brazing alloy for Copper, Brass, Steel, and Nickel alloys, finding applications in diverse industries including Cutting Tools, Medical, Dental and Hospital equipment, Electric and Automotive applications, and Plumbing. The brazed joints typically operate within a temperature range of -200°C to +300°C, maintaining their strength. Proper cooling (a controlled quench exceeding 300°C) is crucial for optimal joint strength.
