1. Introducci\u00f3n\u00a0<\/span><\/strong>7A09\u00a0<\/span><\/strong>Materiales<\/span><\/strong><\/p>\n

7A09 pertenece al aluminio superduro Al-Zn-Mg-Cu. Esta aleaci\u00f3n es una aleaci\u00f3n de aluminio de deformaci\u00f3n ultrarresistente que se ha utilizado en la industria de fabricaci\u00f3n de aviones a finales de la d\u00e9cada de 1940 y todav\u00eda se utiliza ampliamente en la industria aeron\u00e1utica. Sus caracter\u00edsticas son que tiene buena plasticidad despu\u00e9s del tratamiento de soluci\u00f3n s\u00f3lida, especialmente buen efecto de refuerzo del tratamiento t\u00e9rmico, alta resistencia por debajo de 150\u2103, y particularmente buena resistencia a baja temperatura; pobre rendimiento de soldadura; tiende al agrietamiento por corrosi\u00f3n bajo tensi\u00f3n; necesita ser utilizado por recubrimiento de aluminio u otro tratamiento de protecci\u00f3n. El envejecimiento en dos etapas puede mejorar la capacidad de la aleaci\u00f3n para resistir el agrietamiento por corrosi\u00f3n bajo tensi\u00f3n. La plasticidad en los estados recocido y templado r\u00edgido es ligeramente inferior a la del mismo estado 2A12. Es ligeramente mejor que la 7A04. La fatiga est\u00e1tica, la sensibilidad a la entalla de la chapa y el comportamiento a la corrosi\u00f3n bajo tensi\u00f3n son mejores que los de 7A04.<\/span><\/p>\n

El 7A09 se utiliza principalmente para fabricar estructuras aeron\u00e1uticas y otras piezas estructurales sometidas a grandes esfuerzos que requieren una gran resistencia y resistencia a la corrosi\u00f3n, como los paneles de las paredes superior e inferior de las alas de los aviones, larguerillos, etc. Tiene buena plasticidad tras el tratamiento de soluci\u00f3n s\u00f3lida, buen efecto de refuerzo del tratamiento t\u00e9rmico y buena resistencia por debajo de 150 grados. Tambi\u00e9n se utiliza ampliamente en el procesamiento de moldes, equipos mec\u00e1nicos, herramientas y accesorios, industria aeroespacial, moldes de soldadura de pl\u00e1stico por ultrasonidos, cabezas de pelotas de golf, moldes de zapatos, moldes de papel, moldes de espuma, moldes de eliminaci\u00f3n de cera, equipos mec\u00e1nicos, paneles de pared de aeronaves, vigas delanteras, juntas, pilares y trenes de aterrizaje y otras piezas estructurales, moldes, instrumentos de belleza, carcasas de port\u00e1tiles, componentes de alta resistencia, piezas forjadas pesadas, etc.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
