Features and Characteristics of Bearing Silver Brazing Alloys
- Lower brazing temperatures than cadmium-free alloys.
- Great flow and mechanical characteristics.
- Lower silver content when comparing to equivalent cadmium-free alloys.
Parent Metals that can be joined with Cadmium Bearing Silver Brazing Alloys
- Copper and copper alloys including: brasses, bronzes, copper nickel, silver nickel and aluminum bronze.
- Nickel and nickel alloys.
- Stainless Steels.
- Steel – including mild, carbon and low alloy steel.
- Tungsten Carbide and PCD segments.
Precautions
Technical Considerations and Health and Safety Precautions
When brazing with cadmium bearing alloys, considerations have to be taken into account regarding personnel´s health and safety. Cadmium fumes are hazardous and equipment is necessary to efficiently extract these during the brazing operation. Cadmium bearing alloys should not be used in the manufacture of food/drinks handling equipment as well as medical/dental instruments. In such cases, cadmium free alloys should be used – please refer to Cennabras cadmium-free silver alloys.
* Tensile/shear strength data refers to the application on Steel SAE 1020.
** Recommended gap is at brazing temperature and for air brazing processes. For furnace brazing or further details, please contact Cennabras.
*** Other forms can be manufactured upon request. Please contact Cennabras for further information.
