View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.AMZIRC is an oxygen-free copper containing zirconium. AMZIRC copper was developed for applications demanding high electrical conductivity and the retention of strength at elevated temperatures. Applications include stud bases for power transmitters and rectifiers, switches and circuit breakers for high-temperature service, commutators and resistance welding tips and wheels.
