3. Main application / Special features of EN AW – 2017A:

A resilient material with increased strength values, which is mainly used in hydraulics. Use at elevated operating temperatures above 120 ° to 180 ° C. Since normally only cold cured (T451) is used, problems can arise with larger thicknesses due to residual stress. Particularly with asymmetrical machining
