Abstract

ESTA INVENCION SE REFIERE A COMPOSICIONES METALURGICAS EN POLVO Y EN PARTICULAR A COMPOSICIONES METALURGICAS EN POLVO QUE INCORPORAN PLOMO PARA MEJORAR EL MAQUINADO DE LA COMPOSICION RESULTANTE. LOS DEMANDANTES DE LA PATENTE HAN DESCUBIERTO QUE EL CONTENIDO DE PLOMO DE LA COMPOSICION SE PUEDE SUSTITUIR POR UNA CANTIDAD EFECTIVA DE BISMUTO. UNA PROPORCION DE BISMUTO PUEDE SER DE UN 35 A UN 65% EN PESO DE LA PROPORCION DE PLOMO QUE SUSTITUYE, LO QUE PERMITE LA PRODUCCION DE UNA COMPOSICION METALURGICA EN POLVO, DE BRONCE EN PARTICULAR SIN TENER QUE UTILIZAR GRANDES CANTIDADES DE PLOMO.
