Car critical sectors to meet European ELV vehicoles directive

Car critical sectors to meet European ELV vehicoles directive

Car critical sectors to meet European ELV vehicoles directive

(OP)
Hi!
The new European ELV vehicoles directive (2000/53/EU) introduces restricions about the content of Lead, Cadmium, Mercury and Cr+6 and about recycling % of new vehicles: to meet its requirements, what are the most critical aspects about automotive materials choice and design?    

RE: Car critical sectors to meet European ELV vehicoles directive

The hexavalent chromium issue has been fairly significant.  New coatings have been developed to meet this requirement.  For example, anything electroplated with zinc is different - new conversion coating or new alloy plating.  Fasteners have been the most affected components, although chromate treatment of aluminium road wheels means they have the largest Cr6+ content of any component.

RE: Car critical sectors to meet European ELV vehicoles directive

This EU directive also bans Lead in machinable steels if over 0.35%, Copper alloys if over 4% and it is banning in machinable Aluminium alloys first if over 0.2% (7/1/2005) and later if over 0.1% (7/1/2008); No more than 0.5% of Lead is beeing tolerated in copper-based brake shoes: are all these requirements technologically feasible?Do exist any kind of used alloys nowdays that don't respect these limits?

RE: Car critical sectors to meet European ELV vehicoles directive

I'm sorry and ashamed too : the limits regarding the percentage of Lead in aluminium alloys are up to 2% and 1%, not 0,2% and 0,1%.....this thread has no more sense.
