6262A aluminium bars
This is an ecologic alloy, it does not have lead, it has good machinability, and high mechanical characeristics. Moreover it has a good resistance to corrosion and suitability to hard, protective and decorative anodizing.
According to EU directives: 2000/53/CE (ELV) - 2002/95/CE (RoHS)
Main applications
macining on high speed automatic lashes, particulars for automotive applications, automatic transmission shafts, valves and clutches, hydraulic parts. Note: it is particularly suitable for the realization of parts not subject to extreme heat solicitations (no more than 140 ° C) and therefore it is appropriate for automotive parts as automatic transmission shafts. For higher temperatures, we suggest to use other Eural alloys, as 6026 or 6064A.
