Aluminium EN AW7075, or Ergal, available in round bars and plates

Ergal 7075 lega alluminio-zinco resistente e leggera

ergal alluminio7075 musolaAlloy 7075 is mainly made of aluminium and zinc, and it stands out for its good mechanical resistance (the best among all aluminium alloys). Generally, binary alloys Al-Zn are not used because Al-Zn-Mg alloys are preferred. Zinc increases resistance and hardness and eases the auto-quenching of the alloy itself.

Al-Mg-Zn alloys, which are thermically treated, have the highest traction resistance. In welded structures, these alloys may compete with some types of steel.

Ergal, or Ergal 55, is available in a wide range of round bars and plates. It is used in many fields, such as aeronautic field, motorcycle and transport industry, and in any highly stressed part.



Technical characteristics of EN AW7075

  • High mechanical resistance
