Abstract

Una tubería corta de carga moldeada que incluye una composición de polvos de metal. Cada polvo de metal puede incluir uno o más tamaños de grano, que pueden ser diferentes de otros tamaños de grano en polvo. Los polvos de metal pueden incluir polvos de metal de transición, polvos de metal que no es de transición y un polvo de metal de bronce. Los polvos de metal pueden incluir un polvo de metal de unión maleable, tal como bronce, y un polvo de metal de unión no maleable. También se describe una carga moldeada que incluye dichas tuberías cortas, así como un método para fabricar la tubería corta de carga moldeada, y una carga moldeada que incluye dicha tubería corta de carga moldeada.
