1. A method for producing a contact element formed at least sectionally from a brass alloy, having the steps of:
providing a blank for the contact element formed at least sectionally from a brass alloy having a lead content ≤0.5%,
changing the microstructure of the blank by a first heat treatment to increase the ß-phase content,
forming the contact element from the blank with a higher ß-phase content, and
changing the microstructure of the formed contact element by a second heat treatment to increase the α-phase content.
