General Composition

Key Features and Benefits of Superon High Ag Cadmium Bearing Grades

High Ag Cadmium Bearing Grades are designed to deliver consistent brazing performance, high joint strength, and ease of application.

Low Melting Temperature

These alloys have some of the lowest melting points among silver-based alloys, helping reduce thermal stress on components.

Excellent Flow Characteristics

Free-flowing behaviour allows the alloy to spread evenly, resulting in complete joint penetration and smooth fillets.

High Joint Strength

Provides strong and durable brazed joints suitable for service temperatures up to 200 degrees Celsius.

Wide Material Compatibility

Suitable for brazing most ferrous and non-ferrous metals under controlled conditions.

Multiple Product Forms

Available in multiple forms, including silver brazing rods, wires, rings, and preforms, these alloys ensure precise joint filling.

Proven Industrial Usage

These alloys have a long history of use in general engineering and fabrication applications.

The combination of easy handling and strong joints makes each silver brazing rod reliable for precision brazing work.
