2033 aluminium bars
This alloy has been developed by EURAL and it is one of the best for high speed automatic lathes. It gives the following advantages: Easy machining with any tool Excellent chip forming performance (thin chip) Longer tool life High mechanical properties Better anodizing and weldability attitude compared to alloys 2011, 2007, 2030. This alloy does not contain neither lead nor tin and therefore it is a good solution for the production of parts under the latest restriction on this topic (2018/740/EU RoHS: Pb ≤ 0,1 starting from 18/05/2021).
