3. Main application / Special features of EN AW-6023:
This alloy has been specially developed for applications in the electronics and automotive industries and is known for its good machining and anodising properties. It is also used as an alternative alloy to EN AW-6012, where lead is replaced by tin and bismuth and all technological properties are retained.
