DESCRIPTION:
Silvaloy A-45T is free flowing, low melting and an excellent substitute
to the cadmium-bearing filler metals with similar silver contents.
Silvaloy A-45T narrow melt range (75F) makes it suitable for manual
or machine feeding into the braze joint. The alloy is best suited
for narrow gap filling in the range of .001-.005 inches. Silvaloy
A-45T is particularly useful in joining steel, copper, copper
alloys; and should be used in conjunction with Ultra Flux. The
ability to join similar as well as dissimilar metals has allowed
for numerous applications in the refrigeration and air conditioning
fields.
PROPERTIES
OF BRAZED JOINTS:
Generally, the joint strength using Silvaloy A-45T 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-45T is up to 400°F in continuous service
and up to 600°F in intermittent service.
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) Z.49.1,
“Safety in Welding and Cutting.” For more complete information,
refer to the Material Safety Data Sheet for Silvaloy A-45T.
AVAILABLE
FORMS:
Standard forms of Silvaloy A-45T are wire and preforms.
