All-State®
No. 53 Alloy for
Zinc Base Castings Torch
Application General
Characteristics All
intermediate range solder for repairing zinc base die castings. This alloy will
produce smooth, dense, porosity free
deposits that have perfect color match on zinc die castings. The base metal is
never melted. Typical
Applications Recommended
for repairing broken parts or building up worn or missing sections of zinc base
die castings. Commonly
used on automotive carburetors, grills, door handles, ornaments, fuel pumps, and
other hardware. Also used
for repairing and salvaging kirksite dies as well as joining zinc die castings
to dissimilar metals including aluminum.

on zinc base castings Procedures
Remove all dirt, grease, and other
material from areas to be joined. Nickel and chromium plating should be
removed by grinding. All sections over
1/8" (3.2mm) thick, bevel 60 to 90 degrees. Joint area should be supported
with carbon or copper backup strips.
Preheat to 400°F (204°C). Use a soft carburizing flame. Heat end of
rod, dip in All-State®
No. 53 Powdered Flux and transfer to joint area. Continue heating until flux turns
clear, melt off small amount
of filler metal and play flame on the alloy until it flows out and bonds. Joint
may be built up without the use of
flux. Cool slowly, then wash in hot water to remove flux residue.
