| Low-Silver Component Brazing Alloy | BAg5CuZnCd | 4.0-6.0 | 50-55 | rem. | 6.0-8.0 | 770-820 | 820-920 | Must be used with silver brazing flux and it has no self-fluxing property.It has a moderate melting range, and its flowability and gap-filling ability are superior to cadmium-free silver brazing alloy of the same silver content.Low silver class is more cost-effective, and the brazed joint possesses good ductility and toughness.However, it has an average corrosion resistance and it is not suitable for high-vibration, impact, or corrosive environment.It is not for the use in food production and medical components. | Primarily used in applications where RoHS compliant environmental requirements are not required. Mainly used for brazing carbon steel, copper, brass, and copper-steel dissimilar metal joints.Widely used in general pipe fittings, plumbing hardware, general tools, low-voltage electrical connectors, and general refrigeration components.Suitable for flame brazing and induction brazing. Not suitable for vacuum brazing | ||

| High-Silver Component Brazing Alloy | BAg12CuZnCd | 11-13 | 40-42 | rem. | 10.0-14.0 | 750-800 | 800-900 | Must be used with appropriate flux. Does not have self-fluxing properties. Lower overall melting range, excellent spreading, wetting, and gap-filling performance. With increasing silver content, brazed plasticity, tensile strength, and impact resistance all improve. Better mechanical properties. Can withstand vibration and impact. | Designed for mid-to-high-end applications, this brazing alloy is suitable for carbon steel, copper alloys, stainless steel, nickel alloys, and carbide cutting tools. Applications include refrigeration compressor parts, hydraulic and pneumatic components, hardware tools, and electrical switch connectors. It can be brazed with dissimilar metals such as steel- copper, steel-stainless steel, and carbide-steel.Brazing can be performed by flame, induction, or furnace brazing, but not vacuum brazing. | ||
