2033
According to EU directives: 2000/53/EU (ELV) - 2018/740/EU (RoHS II)
Presentation
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).
Main applications
automotive industry, electric and electronic industry, precision machining, defense, forging, screws, bolts, nuts, threaded parts of thin thickness.
