Description
of RWMA
Class
20
Al2O3
Dispersion
Strengthened
Copper
Alloy:
Cuberyllium
C15760(RWMA
Class
20) is
a
high
alumina
content
grade
of
dispersion
strengthened
copper.
It
consists
of
a
pure
copper
matrix
containing
finely
dispersed
sub-microscopic
particles
of
Al₂O₃
is
thermally
stable
so
that
it
acts
retard
recrystallization
of
the
copper.
Consequently,
significant
softening
does
not
occur
as
the
result
of
high
temperature
exposure.
Along
with
superior
strength
retention,
thermal
and
electrical
conductivities
are
higher
than
conventional
copper
alloys.
Cuberyllium
C15760,
tihs
grade
is
available
as
rod
and
bar
stock,
strip
and
strip
reroll,
and
large
rounds.
Most
forms
are
available
with
or
without
an
oxygen
free
copper
cladding.
Unless
specified
as
"declad",
Cuberyllium
is
supplied
with
cladding.

Applications of
RWMA
Class
20
Al2O3
Dispersion
Strengthened
Copper Alloy:
Cuberyllium
C15760 is
primarily
designed
for
applications
requiring
the
highest
elevated
temperature
strength
coupled
with
relatively
high
electrical
and
thermal
conductivities.
It
exhibits
a
high
degree
of
resistance
to
softening
after
exposure
to
elevated
temperatures.
Cuberyllium
C15760
has
sufficient
cold
working
charateristics
for
heading,
extrusion
and
some
drawing
and
rolling
operations.
|
Recommended for: |
Resistance welding electrodes |
| Welding electrodes | |
| Solder gun tips and MIG contact tips |
For
applications
requiring
brazed
joints
and
/or
extended
high
temperature
exposure
in
hydrogen-containing
atmospheres
or
vacuum,
low
Oxygen
is
availbale
and
recommended.
