Presentation
Among aluminium alloys for high speed automatic lathes, 2007 and 2030 have the highest mechanical characteristics.
This alloy is the most often selected when it is required to have a good combination of machinability and high mechanical properties. It has low corrosion resistance; therefore it is recommended to have a protective anodizing of finished products.
Main applications
screws, bolts, nuts, threaded bars
