6262A
According to EU directives: 2000/53/CE (ELV) - 2002/95/CE (RoHS)
Presentation
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.
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.
