Title (EN) MACHINABLE COPPER-BASED ALLOY AND METHOD FOR PRODUCING THE SAME
(FR) ALLIAGE USINABLE À BASE DE CUIVRE ET PROCÉDÉ DE FABRICATION DE CE DERNIER
Abstract:
(EN) Alloy containing between 1 % and 20% by weight of Ni, between 1 % and 20% by weight of Sn, between 0.5%, 3% by weight of Pb in Cu which represents at least 50% by weight of the alloy; characterized in that the alloy further contains between 0.01 % and 5% by weight of P or B alone or in combination. The invention also pertains to a metallic product having enhanced mechanical resistance at intermediate temperatures (300°C to 700°C) and excellent machinability. The metallic product of the invention can be advantageously used for the fabrication of connectors, electromechanical, or micromechanical pieces.
(FR) La présente invention porte sur un alliage contenant entre 1 % et 20 % en poids de nickel (Ni), entre 1 % et 20 % en poids d'étain (Sn), entre 0,5 % et 3 % en poids de plomb (Pb), le cuivre (Cu) représentant au moins 50 % en poids de l'alliage. Ledit alliage est caractérisé en ce qu'il contient en outre entre 0,01 % et 5 % en poids de phosphore (P) ou de bore (B) seul ou en combinaison. L'invention se rapporte également à un produit métallique ayant une meilleure résistance mécanique à des températures intermédiaires (allant de 300 °C à 700 °C) et une excellente aptitude à l'usinage. Le produit métallique de l'invention peut être utilisé avantageusement pour la fabrication de connecteurs ou de pièces électromécaniques ou micromécaniques.
