SilverAlloy A-45
Nominal Chemical
Composition
INTRODUCTION
Aufhauser SilverAlloy A-45 is a good general purpose brazing alloy used for most metals except aluminum and magnesium.
APPLICATIONS
Often used when cadmium must be avoided such as in the dairy and food industries. Typical applications are the joining of ferrous, nonferrous and dissimilar metals. It is used for brazing in the electrical industry and for brazing brass parts such as ships, piping, band instruments and lamps. Excellent replacement to cadmium containing alloys. Broad application in furnace brazing.
GENERAL INFORMATION
Chemical Composition| Silver | Copper | Zinc | Total other |
|---|---|---|---|
| 44.0-46.0 | 29.0-31.0 | 23.0-27.0 | 0.15 max |
ADDITIONAL INFORMATION
Generally, the joint strength using SilverAlloy A-45 will surpass the strengths of the base metals. Strength is a function of the base metals being joined, type of joint, design of joint, joint clearances and brazing procedures.
