Title (EN) LEADLESS FREE-CUTTING COPPER ALLOY AND METHOD FOR PRODUCING THE SAME
(FR) ALLIAGE DE DÉCOLLETAGE EN CUIVRE SANS PLOMB ET SON PROCÉDÉ DE PRODUCTION
Abstract: front page image
(EN)Disclosed is a leadless free-cutting copper alloy that exhibits superior machinability, cold workability and dezincification resistance and a method for producing the same. The leadless free-cutting copper alloy comprises 56 to 77% by weight of copper (Cu), 0.1 to 3.0% by weight of manganese (Mn), 1.5 to 3.5% by weight of silicon (Si), and the balance of zinc (Zn) and other inevitable impurities, thus exhibiting superior eco-friendliness, machinability, cold workability and dezincification resistance.
(FR)La présente invention se rapporte à un alliage de décolletage en cuivre sans plomb qui présente de meilleures usinabilité, maniabilité à froid et résistance à la dézincification ainsi qu'à son procédé de production. L'alliage de décolletage en cuivre sans plomb comprend de 56 à 77 % en poids de cuivre (Cu), de 0,1 à 3,0 % en poids de manganèse (Mn), de 1.5 à 3,5 % en poids de silicium (Si), et le reste de zinc (Zn) et d'autres impuretés inévitables, offrant ainsi de meilleurs caractère écologique, usinabilité, maniabilité à froid et résistance à la dézincification.
