This is a short chipped aluminium alloy containing between 3.3 – 4.6% copper. It is very suitable for high machining speeds and ideal for threading. In addition to copper, it also contains magnesium and lead. This material is commonly used for the production of machine parts, bolts, and nuts. However, its copper content gives it low weldability and low resistance to corrosion.
Excellent machinability • Heat treatable • Low weldability • Low corrosion resistance
