Aufhauser SilverAlloy A-30 is a good general purpose brazing alloy.
SilverAlloy A-30 does not contain cadmium and is often used as an alternate to cadmium-containing alloys when the brazed assembly comes in contact with food or dairy products. Its slightly higher melt temperature provides improved mechanical strengths when exposed to elevated temperatures. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances. It is used extensively in joining of copper, brass, nickel, silver, and ferrous alloys. Good for refrigeration assemblies where higher temperatures can be employed.
GENERAL INFORMATIONCHEMICAL COMPOSITION
Generally, the joint strength using SilverAlloy A-30 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. The recommended maximum operating temperature for SilverAlloy A-30 is up to 400°F in continuous service and up to 600°F in intermittent service. Where improved corrosion resistance is needed SilverAlloy A-50N and SilverAlloy A-40N2 are recommended over silver base filler metals not containing nickel.
