Su alto contenido de esta\u00f1o lo hace mucho m\u00e1s duro que los bronces comunes y le da un tono brillante, sostenido y resonante, raz\u00f3n por la cual los bronces de alto esta\u00f1o de este tipo son las aleaciones tradicionales para campanas, gongs y carillones. Su rango de fusi\u00f3n es de aproximadamente 1,450\u20131,630\u00b0F (788\u2013888\u00b0C).<\/p>\n<p>Adem\u00e1s de campanas y otras piezas musicales, el cobre-esta\u00f1o 80\/20 se usa para piezas fundidas especiales resistentes al desgaste, como aleaci\u00f3n aglutinante para herramientas de diamante y abrasivos, y como fuente concentrada de esta\u00f1o para aleaci\u00f3n, ya que aporta el doble de esta\u00f1o por libra que el cobre-esta\u00f1o 90\/10. El bronce de alto esta\u00f1o es fr\u00e1gil en estado de colada, por lo que se manipula y se termina de manera distinta a los bronces comunes.<\/p>\n<p>Se suministra en piezas pulidas de 3\/8&#8243; x 1\/2&#8243; x 1\/2&#8243; para una fusi\u00f3n limpia y precisa.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Metal de campana de alto esta\u00f1o (80% Cu, 20% Sn) para fundir campanas, gongs y otras piezas resonantes.
