C15000
99.85Cu-0.15Zr
Commercial Names
Trade name. Amzirc Brand copper; N-4 alloy
Common name. Zirconium-copper
Chemical Composition
Composition limits. 99.95 Cu + Ag + Zr min, 0.13 to 0.20
Zr
Applications
Typical uses. Stud bases for power transmitters and
rectifiers, switches and circuit breakers for hightemperature
service, commutators, resistance welding
tips and wheels, solderless wrapped connectors.
Zirconium-copper is heat treatable and retains much of
its room-temperature strength up to 450 °C (840 °F).
Precautions in use. During hot working, forging should be
discontinued if the temperature falls below 800 °C (1470
°F). The part must be reheated to at least 900 °C (1650
°F) before forging can be resumed.
Mechanical Properties
Tensile properties. See Tables 18 and 19, and Fig. 18.
