Method of manufacturing centrifugal cast alloy and improvement of physical properties

摘要

The present invention relates to a manufacturing method of centrifugal casting alloy using waste copper scrap and a method of improving mechanical properties. In adjusting copper alloy for centrifugal casting using the waste copper scrap, according to the present invention, the composition comprises 512 to 14 wt% of Sn, 14 to 16 wt% of Ni, 13 to 14 wt% of Pb, 046 to 048 wt% of Sb, 006 to 008 wt% of P, and the balance of Cu.
