• Performance characteristics: They have a low melting point, excellent processability, good wetting properties, and the ability to fill gaps. The brazed joints exhibit high strength, good ductility, and excellent electrical conductivity and corrosion resistance.

    • Common Types and Composition: Common types include HAG-2B silver brazing rings with 2% silver content; HAG-25B silver brazing rings with 25% silver content, which are silver-copper-zinc-tin alloys; and HAG-45B silver brazing rings with 45% silver content, which are silver-copper-zinc-tin alloys. Different types vary in melting point and performance due to differing compositions.

    •    Specifications and dimensions: The wire diameter typically ranges from Φ0.4 to Φ3.0 mm, with an inner diameter of Φ3.5 mm or larger. Customised specifications can be provided upon request.

•    Welding process: Suitable for high-frequency welding, gas welding, and oxygen welding. Commonly used for welding stainless steel, brass, bronze, iron, and other metallic materials. During welding, a suitable flux is typically required to enhance weld quality.

    • Application Areas: Widely used in industrial manufacturing sectors such as refrigeration, lighting fixtures, hardware and electrical appliances, instruments and meters, chemicals, and aerospace, including maintenance of refrigeration equipment like air conditioners and refrigerators, welding of electronic components, and jewellery processing.

• Recycling Value: Due to its silver content, silver solder rings have high recycling value. Recycling prices vary depending on silver content, with higher silver content resulting in higher recycling prices.
