#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. It is used extensively in joining of copper, brass, nickel-silvers, and ferrous alloys.

Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances.

Good for refrigeration assemblies where higher temperatures can be employed. Copper, nickel-silvers, and other non ferrous.

Available Forms

Standard forms of #A-30 are wire, strip, and preforms.

Safety Information

It is essential that adequate ventilation be provided so that personnel will not inhale gases and fumes while brazing. The operation and maintenance of brazing equipment or facility should conform to the provisions of America National Standard ANSI/ASC Z49.1, "Safety in Welding, Cutting and Allied Processing". For more complete information, refer to

the Material Safety Data Sheet for #A-30.
