Aleaciones para fundici\u00f3n a presi\u00f3n<\/h1>\n

Aleaciones de fundici\u00f3n a presi\u00f3n<\/strong><\/em><\/a> normalmente no son ferrosos, y existe un gran n\u00famero de ellos con una amplia gama de propiedades f\u00edsicas y mec\u00e1nicas que cubren casi todas las aplicaciones imaginables que pueda necesitar un dise\u00f1ador.<\/span><\/small><\/p>\n

Las aleaciones de aluminio y zinc son las m\u00e1s utilizadas, seguidas de las de magnesio, zinc-aluminio (AZ), cobre, esta\u00f1o y plomo.<\/span><\/small><\/p>\n

Las aleaciones a base de zinc, plomo y esta\u00f1o se clasifican como metales de bajo punto de fusi\u00f3n, ya que todos se funden a menos de 725o<\/sup>F (385o<\/sup>C). Las aleaciones de zinc-aluminio (ZA) tienen un intervalo de fusi\u00f3n ligeramente superior, de 800o<\/sup>F a 900o<\/sup>F (426o<\/sup>C a 482o<\/sup>C). Las aleaciones de aluminio y magnesio se consideran aleaciones de punto de fusi\u00f3n moderado, fundi\u00e9ndose en el intervalo de 1150o<\/sup>F a 1300o<\/sup>F (621o<\/sup>C a 704o<\/sup>C). Las aleaciones de cobre se consideran de alto punto de fusi\u00f3n, m\u00e1s de 1650o<\/sup>F (899o<\/sup>C). Las aleaciones de bajo punto de fusi\u00f3n se funden en m\u00e1quinas de c\u00e1mara caliente. Las aleaciones de punto de fusi\u00f3n intermedio y alto se funden en m\u00e1quinas de c\u00e1mara fr\u00eda. En los \u00faltimos a\u00f1os se han empezado a utilizar m\u00e1quinas de c\u00e1mara caliente especialmente dise\u00f1adas para la fundici\u00f3n a presi\u00f3n de aleaciones de magnesio.<\/span><\/small><\/p>\n

Die Casting Alloys Die casting alloys are normally non-ferrous, and there is a large number available with a wide range of physical and mechanical properties covering almost every conceivable application a designer might require. Aluminum and zinc alloys are the most widely used, and are followed by magnesium, zinc-aluminum (AZ) alloys, copper, tin and lead.
