COPPER ALLOY
DATA SHEET
ACB C15000
Zirconium Copper C15000 is
an important and unique copper alloy with high electrical conductivity,
hardness, and ductility, moderate strength, and excellent resistance to
softening at elevated temperatures. The
addition of 0.15% zirconium (Zr) to copper results in a heat treatable copper
alloy which may be solution treated and subsequently aged to produce these
desirable properties. Rod is supplied
from the mill in the fully aged and drawn condition so no further heat
treatment is required by the fabricator.
The softening temperature of properly heat treated C15000 rod exceeds
500°C as compared to unalloyed, pure copper which
softens at 200°C and silver bearing coppers
which soften at 350°C.
Hot and Cold Working: Alloy C15000 has both excellent hot and cold
workability, and work hardens exceptionally well. For hot working, the properties of the alloy
will be dependent upon the hot working temperature, cooling rate, and
subsequent heat treatment. Cold working
operations such as bending, cold heading, and swaging are suitable for
C15000. Rod can be reduced over 50%
without an intermediate anneal.
Joining: Alloy C15000 may be readily joined by
soldering or brazing. Joining via oxyacetylene, arc
welding or resistance welding are not recommended.
Applications: Since
C15000 is able to retain most of its strength up to 450°C (840°F), it is typically used for
resistance welding electrodes and circuit breaker switches. It also provides the ductility and high
thermal conductivity needed to meet manufacturing and operating conditions for
thin sections such as flat bottom stud bases for power transmitters, rectifiers
and diodes. These type of parts are
destined as heat carriers, and are subject to torque stresses. Using C15000 gives them the high resistance
to torque while allowing them to be tightly mounted for maximum heat transfer.
Applicable Specifications: When so specified, C15000 used for resistance
electrode material will be manufactured to RWMA Bulletin 16 – Group A, Class 1.
Standard Forms Available: Rod,
bar, and wire. For other forms, please
