Abstract
Inventia se refera la un procedeu de obtinere a contactelor electrice sub forma de nit, din aliaje si pseudoaliaje de metale pretioase, care consta din formarea la rece pe masini automate, din sârme rotunde, tratate termic si calibrate prin trefilare, a aniturilor - contact, urmata de un tratament termic de restabilire a proprietatilor electrice si de un tratament chimic de lustruire si pasivare a suprafetei de contact. Procedeul conform inventiei prezinta, fata de alte procedee cunoscute, avantajele unei cresteri substantiale a productivitatii muncii, obtinerii unei game tipodimensionale largi de contacte cu calitati electrice si rezistenta la actiunea mediului ambiant, superioare.
