(FR) ALLIAGE DE DÉCOLLETAGE AU CUIVRE
Abstract: front page image
(EN)The present invention relates to a free-cutting copper alloy containing calcium. The free-cutting copper alloy of the present invention consists of copper Cu, zinc Zn, and calcium Ca, with Cu at 59 ~ 79wt%, Ca at 0.1 ~ 1.5wt%, and zinc in remainder. The free-cutting copper alloy has inter-metallic compound of calcium and copper in a matrix, thereby improving industrial machinability.
(FR)La présente invention concerne un alliage de décolletage au cuivre contenant du calcium. Cet alliage est constitué de cuivre (Cu) pour 59 à 79 % du poids, de calcium (Ca) pour 0,1 à 1,5 % du poids, et de zinc (Zn) pour le restant.
