DESCRIPTION:
Silvaloy A-45 is a good general purpose alloy often used when
cadmium must be avoided such as in the dairy and food industries.
It is also used for brazing in the electrical industry and for
brazing brass parts such as ships’ piping, band instruments, lamps,
etc.
PROPERTIES
OF BRAZED JOINTS:
Generally, the joint strength using Silvaloy 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. The recommended maximum operating
temperature for Silvaloy A-45 is up to 400°F in continuos service
and up to 600°F in intermittent services. Where improved corrosion
resistance is needed, Silvaloy A-50N and Silvaloy A-40N2 are recommended
over silver base filler metals not containing nickel.
APPLICATIONS:
Typical applications are the joining of ferrous, nonferrous and
dissimilar metals and alloys with close joint clearances.

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 American National Standard (ANSI) Z49.1,
“Safety in Welding and Cutting.” For more complete information,
refer to the Material Safety Data Sheet for Silvaloy A-45.
AVAILABLE
FORMS:
Standard forms of Silvaloy A-45 are wire, strip, and preforms.
