Q:
|
What types
of filler metal forms are there?
|
A:
|
Filler metals
come in wire, strip, powder, or paste form. Availability
in these forms depends on the alloy that is chosen.
Preforms can be made from strip and wire.
|
Q:
|
What is
oxidization?
|
A:
|
When metals
are exposed to oxygen, oxides form from oxygen atoms
that attach to the metal. The oxides that form prevent
the molten alloy from metallurgically joining to the
metal.
|
Q:
|
What is
Flux?
|
A:
|
Flux is a
chemical compound that is applied and shields the joint
surface from air and prevents oxide formation. Although
flux will dissolve and absorb oxides, the metals that
are being joined should be properly cleaned prior to
brazing.
|
Q:
|
What are
the available flux forms?
|
A:
|
Flux is available
from Lucas-Milhaupt in paste, slurry, liquid and powder
form depending on the type of flux. Paste, slurry, and
liquid fluxes are all water based while dispensable
fluxes are petroleum based. Flux can also be delivered
to the joint through the torch that is being used.

Pre-packaged brazing
filler metals, fluxes, and solders, including Sil-Fos®,
developed and patented by Handy & Harman in 1931, the original
copper/phosphorous brazing alloy used by thousands of manufacturers
and contractors.
Available either in bulk or pre-packaged lots are filler metals
for brazing copper-based alloys (Sil-Fos®), steels, stainless,
etc. (Braze™ and Easy-Flo® Alloys), as well as low
temperature, lead-bearing (Solderite™) and no-lead solders
(Clean ‘n Brite™).
