Ergal 7075 lega alluminio-zinco resistente e leggera
Alloy 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.
