  • Copper base alloys for automotive radiator fins, electrical connectors and commutators
    Patent number: 4492602
    Abstract: The present invention relates to novel tin bearing copper alloy compositions that possess a combination of high anneal resistance and high electrical cconductivity properties. These compositions contain about 0.025 to 0.15 weight percent free tin with a weight percent of combined tin that is 3.7 times the oxygen content. Selenium and/or tellurium additions of from 0.005 to 0.05 weight percent also contribute to or maintain the improved properties of the present invention.Other aspects of the invention relate to a process for preparing these anneal resistant, high electrical conductivity copper alloy compositions and an apparatus suitable for use as radiator fin, electrical connector, or commutator segment stock which is formed by such process.
